There is another way of keeping time that you did not mention, likely because it was obly recently rediscovered... The True Clock and Calendar of YaHUaH. יהוה Spica=Abib... Fully restored or full moon for beginning of months. Days starting with dawn and ending in the esrly morning before dawn... With a star or cluster heralding in the appointed times of יהוה. The mark of the beast keeps y'all away from the Truth, because it is a tool of control... Like language.
Bet you also didn't know how on the last evening of the moon cycle the sun will set then the moon 🌕 rises from the East, next, the "moon rules the night with the stars" and sets as the sun dawns greeting each other in the morning sky marking a "new month day". This system also uses a 13th moon cycle like the Macedonians, as stated throughout Scripture and historically with historians like Josephus. I'm surprised that this "expert" doesn't know this, not did she tell us how some Nations used the full moon cycle, only the wicked nations like the Babylonians/Assyrians/Greeks/Romans used a crescent 🌙 to start the months.

I have studied Astro Navigation and learned about lunar , sidereal solar time before, but I wish this lecture was available back in Navigation classes.

Good presentation. One item she did not discuss was the adoption of an international date line, and why we have one in the first place. Would be interesting to hear her take on it.
The international date line will always have to go somewhere, as these are just lectures, until we bang heads together & devise the best calendar. Ideally it would start around March 21st & have 13 months of 28 days with a new month of Vern/Vernuary slotted in after February. Vern/Vernuary can then be used for leading up to the Vernal Equinox. Leap days can still be added when needed and hopefully we keep February 29th every four years or so, as it's already established!
One natural cycle which I've never seen mentioned in histories of time keeping is the tidal cycle. Yet tides too need to be logged and kept track of in order to make decisions, particularly of course when to enter or leave port, with reference not only to water depth but also flow speed. To this day there's a rule of thumb called the "rule of twelths" used by mariners for this purpose, but I suggest that the convention of dividing clock faces into twelve segments originates with the convenient properties of this number in logging and therefore predicting rise and fall in water height and speed. 1 o'clock tells you that 1/12 of the tidal range (whether spring or neap) has been reached, 2 o'clock that another 2/12's has been added, then 3/12's more at 3 and again at 4. By 5 only another 2/12's, so speed is diminishing, and by 6 only another 1, at which time we have high water and slack water, and the process then goes into reverse over the next 6 hours. The changes in flow speed are represented by the sequence 1 2 3 3 2 1, which sums to 12, and at 6 the water is twice as deep as it was at 3. I don't think other numbers fit as well here as 12 does, except possibly 6, and of course integer multiples of 12. One difficulty that's often associated with using sundials is the inconvenient daylight time length changes over the year, but the tide goes in and out over the same period at a given spot on the coast or tidal river bank throughout the year, maintaining the time length of the hour unit, even though the range changes from spring to neap with the lunar cycle. Moreover, the period between spring and neap tides is roughly 7 days, which might have been the origin of another conventional time unit, the week. If ancient maritime and trading civilisations developed astronomy for navigation, they might have invented this means of time logging too.
@@Ilham-mw7lc Yes, I guess the flooding of the Nile can be seen as a kind of annual high tide instead of a diurnal or semi-diurnal one. Is/was there a corresponding annual low tide? Dividing this cycle into 12ths could have the same advantages as for seashore tides.
I don't see that calendar as much different from the solar only Gregorian calendar. Genesis 1:14 explains the Torah principle of two or three witnesses to confirm a matter? And ELOHIYM said, Let there be lights in the expanse of the heavens to divide the day from the night; and let them be for signs, and for appointed feasts, and for days, and years: And let them be for lights in the expanse of the heavens to give light upon the earth: and it was so. And ELOHIYM made את eth-two great lights; את eth-the greater light to rule the day, and את eth-the lesser light to rule the night: he made the stars also. And ELOHIYM set them in the expanse of the heavens to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and ELOHIYM saw that it was good. And the evening and the morning were the fourth day. BERE'SHIYTH (GENESIS) 1:14-19 את CEPHER
Incredible presentation! Now I feel like I'm accidentally dropped in a random location in a space rock that wobbles at irregular intervals around a fire rock, and that every order ever percieved by my senses is but a mere illusion.
Almost every single experience you and I have today is an illusion (an idea) created by other humans hundreds or thousands of years ago. Every single human concept or idea that we experience today is based on past failed attempts to give order to completely chaotic systems in nature. So technically you and I currently live in a simulation of reality because "reality" as we now know it is almost entirely based on human concepts and ideas. Time is an illusion, but so is everything else. (tl;dr) We live in the matrix bro.
Currently studying gematria and heard it mentioned that the gregorian calendar was created to also fit the language of numerology. Your excellent lecture gave me deeper clarity into the way the Romans would also count backwards, which is a used cipher within gematria. So interesting, especially as its still being used today by the Society of Jesus and freemasonry.
I have a physics question for you. If a quarts watch runs on frequencies, and people can have different frequencies depending on the individual wearing the watch. Can the time on quarts watch be effected by the frequency of the person wearing the watch? Does a person's magnetic field or frequency mess with the way they perceive the concept of time. is dragging or time is flying by in a 24 hour period. Always been super curious about it.
You're right. Time is subjective. If you're curious, look into flat earth and see how the heliocentric model is just a solar calendar. I've just done a video about it.
I have two questions. 1) Why are there 13 days marked as "XVIII Kal." in her Roman Calendar example? 2) According to her, the offset is: - 11 minutes (appx.) every 4 years; - A day has 1440 minutes; - It'd take 130,90 leaps (523 years) for the delay to reach 1 day. How could the Gregorian Calendar be 10 days out of synch (and 11 on England 200 years later)? Even if that 11 is an approximation, 10 or 12 minutes wouldn't make such a difference. Am I missing something?
If we didnt need time n motion for modern society it wouldnt matter to ordinary folks. They live, they love, they work n they die. Just like you dont need to know about building a car they wouldnt need to know what year it was. Just agricultural seasons would be important to everyone.
There is nothing scientific about calendar. It is just matter of convenience. George Eastman's 13 month Calendar would be most convenient of them all provided it most people use it. George Eastman did use it intra Kodak company when he was alive. But convenience is lost if most people don't use it.

What I most wanted to know was the one thing she did not tell me. And that is what year was it before the invention of B.C. and A.D.? In other words, we would say Julius Caesar was assassinated on the Ides of March or March 15th 44 B.C. - but Romans would not say "44 BC" so what would they have said the year was? It was during the Republic so there was no "1st year of the reign of Augustus" yet, and would not be for years until he consolidated power in 27 BC a few years after the defeat and deaths of Mark Antony and Queen Cleopatra in 30 BC, so how were years identified then, before the first emperor was an Emporer?
This is a great lecture! But can someone help me out, did I miss something? On her “Romanized calendar” for February 2016, all the days after VIII Kal. March are VIII Kal. Until the Ides. Shouldn’t they be IX Kal., X Kal., XI Kal., etc.? Did I miss something or is her slide messed up? It happens when she asks the person when their birthday is this month.
I saw this too and wondered, but I believe she explained it without saying that's what it was. I know this isn't a great answer to your question, but she speaks to it not aligning.
Actually, the calendar we use is the _Roman Catholic_ calendar - or the Gregorian Calendar. The names of some months *are* Roman and 3 weekdays. The rest is a bit of a hodge-podge. en.wikipedia.org/wiki/Gregorian_calendar
I have watched this more than I can I can remember. I knew about the calendar back untill Gregory times but now it's refreshing to go far back as to it's origin. The first king of Rome kingdom in 731BC.
The fact that we still use September/October/etc., but for the months 9-12, just goes to show how much humans have a habit for hacking systems together on top of older, flawed systems. We do this everywhere if you look hard enough.
Nature has and always will disrupt man made models. This is the power point I took away from this observational discussion, because anyone who has lived any length of so called time knows that change is a constant, and why models are reformulated at a feeble attempt to compensate for the unknown variables nature puzzles science with.

If Science was understood to become important around 450 AD, it was too late to realise it. On the contrary, the Eastern calendars that originated in India for almost 1000s of years earlier were very scientific with absolutely no selfish names to months or weeks. The world needs to know that every name was associated with nature and every year in a cycle of 60 years also have unique names.
It is an interesting narrative but as a trained historian I have some difficulty accepting Romulus as an existing historical figure. On Roman religion you can read my grandfather's La Religione Romana (G.B. Pighi) supplemented by more modern research.
I'm glad to see that I'm not the only one that researches for fun. Thank you for mentioning the 8th day that got lost when the Pope assigned Sunday as the day of worship. Nobody mentions that so not many people know the 8th day ever existed. People celebrated twice because people were sticking to ancient traditions. I still believe we are out of alignment. Winner is always later every year in Florida. Winter was November when I was a child. Now it's February March.
Also in FL, and yes, the seasons are changing and shifting a little each year. I have not been able to come up with a calculation for it, but I do believe it has something to do with the calendar changes. We're not tracking years and the seasons of each year properly in the present day and I haven't been able to pinpoint a single cause. It's a mess to unravel!!!

Lecture had some factual errors. Romulus and Numa are legendary figures who may or may not have existed. So it's far from certain they had anything to do with the Roman calendar. Also, the notion that August had an extra day added to match July is generally believed to be a myth. The seven day cycle named after the first hour's planet was around well before Constantine. Dennis the Small (actually Dionysius Exiguus) did NOT invent the concept of 'BC' and 'AD'. He merely computed a table of Easter dates in which he numbered the years from the nativity of Jesus. It was a later scholar, the Venerable Bede who introduced the 'BC' concept in his historical writings. While it was known that spring equinox was falling several days before March 21 centuries before the Gregorian reform, the statement that it led to Christians being mocked seems a bit much.
What is the address to your video, audio, written explanation of the facts about calendation? I am researching the original YAH given calendar of sun, moon and stars from day four of creation and question what parts of YAH's calendar does Judaism, Catholicism, Islam, or Protestant Christianity have correct?

Wait, if the gregorian calendar subtracted 10 days from the Julian calendar, which was about 365.25 days in a year, then whats the explanation for why the gregorian calendar has 365.2425 days in a year?
365.24667days is the length of the year. The .24667 days is slightly short of a quarter day. The Julian calendar address that extra fraction of a day by adding a leap day every four years to compensate for that extra quarter day per year. However it is a slight over correction. To address this problem Pope Gregory brought the calendar back in sync with the seasons by subtracting the ten day drift. Then to prevent the extra three day drift per four hundred year period he dictated that years divisible by 100 but not 400 will not be leap years. For example, the year 2000 was a leap year but 2100,2200,and 2300 will not be leap years. Even though 1896 and 1904 were leap years, 1900 was not. This happens to also be an overcorrection but the drift is so small that it will be thousands of years before it will be further modified.Perhaps the .2425 is the result of the four hundred year rule I described above.

And command you the children of Yashar'el that they observe the years according to this reckoning 👉three hundred and sixty four days, and these will constitute a complete year 👈, and they will not disturb its time from its days and from its feasts; for everything will fall out in them according to their testimony, and they will not leave out any day nor disturb any feasts. But if they do neglect and do not observe them according to his commandment, then they will disturb all their seasons and the years will be dislodged from this order, and they will disturb the seasons and the years will be dislodged and they will neglect their ordinances. And all the children of Yashar'el will forget and will not find the path of the years, and will forget the New Moons, and seasons, and Shabbaths and they will go wrong as to all the order of the years. For I know and from henceforth will I declare it unto you, and it is not of my own devising; for the cepher lies written before me, and on the heavenly tablets the division of days is ordained, lest they forget the feasts of the covenant and walk according to the feasts of the other nations after their error and after their ignorance. 👉For there will be those who will assuredly make observations of the moon how it disturbs the seasons and comes in from year to year ten days too soon. For this reason the years will come upon them when they will disturb the order, and make an abominable day the day of testimony, and an unclean day a feast day, and they will confound all the days, the holy with the unclean, and the unclean day with the holy; for they will go wrong as to the months and Shabbaths and feasts and jubilees. 👉For this reason I command and testify to you that you may testify to them; for after your death your children will disturb them, so that they will not make the year three hundred and sixty four days ONLY, and for this reason they will go wrong as to the New Moons and seasons and Shabbaths and feasts, and they will eat all kinds of blood with all kinds of flesh. YOVHELIYM (JUBILEES) 6:32-38
Babylonian calendar is base on moon whether Egyptian calendar is based on sun booth predates roman, julian, gregorian calendar. Lunar calendar is far more sophisticated they dont have problem like the solar calendar use to have. Its simple you see the new moon that marks the beginning of new month. But determining a month by position of sun is relatively insane. They excuse season but seasons are adversre in northen & southern hemisphere relative to sun that just make no sense. Whether lunar calendar doesnt affected by these phenomenon. Season is not importan in lunar calendar. Come to cultivation people till to date does not plant on any particular day rather they have their own sense & signs to do so. Modern standerd time is still very young (1884).
not really correct to say they didn't have fractions. No they didn't have decimal-fractions (0.75) , but they did have whole number fractions such a 3/4 means 3 divided by 4, is three-quarter, 3 of 4. They prove this when they do things like roll a one-cubit stone radius to get length that we then think was a ruler of pi.

1 o'clock tells you that 1/12 of the tidal range (whether spring or neap) has been reached, 2 o'clock that another 2/12's has been added, then 3/12's more at 3 and again at 4. By 5 only another 2/12's, so speed is diminishing, and by 6 only another 1, at which time we have high water and slack water, and the process then goes into reverse over the next 6 hours. The changes in flow speed are represented by the sequence 1 2 3 3 2 1, which sums to 12, and at 6 the water is twice as deep as it was at 3. I don't think other numbers fit as well here as 12 does, except possibly 6, and of course integer multiples of 12.
One difficulty that's often associated with using sundials is the inconvenient daylight time length changes over the year, but the tide goes in and out over the same period at a given spot on the coast or tidal river bank throughout the year, maintaining the time length of the hour unit, even though the range changes from spring to neap with the lunar cycle. Moreover, the period between spring and neap tides is roughly 7 days, which might have been the origin of another conventional time unit, the week. If ancient maritime and trading civilisations developed astronomy for navigation, they might have invented this means of time logging too.
It is mentioned briefly at around 4:23
@@Ilham-mw7lc Yes, I guess the flooding of the Nile can be seen as a kind of annual high tide instead of a diurnal or semi-diurnal one. Is/was there a corresponding annual low tide? Dividing this cycle into 12ths could have the same advantages as for seashore tides.
This was awesome, thank you. I've taken notes
FINALLY a video which explains this stuff well.
Wow - Thank you
From South Africa
just great!
32:10 what i really wanted to know
how did people talk about years before AD BC
very interesting lecture
Great example How a consept evolv over time and gets better and better
I wish you'd have added the qumran-enoch/zadok priestly calendar (derived from Scripture) to your list. Great survey thank you
I don't see that calendar as much different from the solar only Gregorian calendar. Genesis 1:14 explains the Torah principle of two or three witnesses to confirm a matter?
And ELOHIYM said, Let there be lights in the expanse of the heavens to divide the day from the night; and let them be for signs, and for appointed feasts, and for days, and years: And let them be for lights in the expanse of the heavens to give light upon the earth: and it was so. And ELOHIYM made את eth-two great lights; את eth-the greater light to rule the day, and את eth-the lesser light to rule the night: he made the stars also. And ELOHIYM set them in the expanse of the heavens to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and ELOHIYM saw that it was good. And the evening and the morning were the fourth day. BERE'SHIYTH (GENESIS) 1:14-19 את CEPHER
Incredible presentation! Now I feel like I'm accidentally dropped in a random location in a space rock that wobbles at irregular intervals around a fire rock, and that every order ever percieved by my senses is but a mere illusion.
Almost every single experience you and I have today is an illusion (an idea) created by other humans hundreds or thousands of years ago. Every single human concept or idea that we experience today is based on past failed attempts to give order to completely chaotic systems in nature. So technically you and I currently live in a simulation of reality because "reality" as we now know it is almost entirely based on human concepts and ideas. Time is an illusion, but so is everything else.
(tl;dr) We live in the matrix bro.
Currently studying gematria and heard it mentioned that the gregorian calendar was created to also fit the language of numerology. Your excellent lecture gave me deeper clarity into the way the Romans would also count backwards, which is a used cipher within gematria. So interesting, especially as its still being used today by the Society of Jesus and freemasonry.
The last line being all important.
This video was in 2016, Who is still watching in 2022?
It’s 2024 it my realm

I have a physics question for you. If a quarts watch runs on frequencies, and people can have different frequencies depending on the individual wearing the watch. Can
the time on quarts watch be effected by the frequency of the person wearing the watch? Does a person's magnetic field or frequency mess with the way they perceive the concept of time. is dragging or time is flying by in a 24 hour period. Always been super curious about it.
You're right. Time is subjective. If you're curious, look into flat earth and see how the heliocentric model is just a solar calendar. I've just done a video about it.
Great talk thanks
I have two questions.
1) Why are there 13 days marked as "XVIII Kal." in her Roman Calendar example?
2) According to her, the offset is:
- 11 minutes (appx.) every 4 years;
- A day has 1440 minutes;
- It'd take 130,90 leaps (523 years) for the delay to reach 1 day.
How could the Gregorian Calendar be 10 days out of synch (and 11 on England 200 years later)? Even if that 11 is an approximation, 10 or 12 minutes wouldn't make such a difference. Am I missing something?
If we hadnt been adding any extra days for the last 2000 yrs it would now be Nov 2018 in summertime. Glory to God.
Very educative
Thank you.
Me who used this video just to listen and clean my room at the same time for one hour 😐😐
excellent choice
The Roman calendar appears so unscientific. The high priests practically dictated the terms to the ignorant masses.
If we didnt need time n motion for modern society it wouldnt matter to ordinary folks. They live, they love, they work n they die. Just like you dont need to know about building a car they wouldnt need to know what year it was. Just agricultural seasons would be important to everyone.
yeah....no perfect system or practice started off perfect. Also, seems a little silly to be criticizing the ancients with the benefit of modernity.
There is nothing scientific about calendar. It is just matter of convenience. George Eastman's 13 month Calendar would be most convenient of them all provided it most people use it. George Eastman did use it intra Kodak company when he was alive. But convenience is lost if most people don't use it.

What I most wanted to know was the one thing she did not tell me. And that is what year was it before the invention of B.C. and A.D.? In other words, we would say Julius Caesar was assassinated on the Ides of March or March 15th 44 B.C. - but Romans would not say "44 BC" so what would they have said the year was? It was during the Republic so there was no "1st year of the reign of Augustus" yet, and would not be for years until he consolidated power in 27 BC a few years after the defeat and deaths of Mark Antony and Queen Cleopatra in 30 BC, so how were years identified then, before the first emperor was an Emporer?
The year was identified by the two annual consuls.
The real second, or what one might call a natural second, is still 1/86400th of a day, and is a tiny bit longer than an Atomic Time second.
This is a great lecture! But can someone help me out, did I miss something? On her “Romanized calendar” for February 2016, all the days after VIII Kal. March are VIII Kal. Until the Ides. Shouldn’t they be IX Kal., X Kal., XI Kal., etc.? Did I miss something or is her slide messed up? It happens when she asks the person when their birthday is this month.
I saw this too and wondered, but I believe she explained it without saying that's what it was. I know this isn't a great answer to your question, but she speaks to it not aligning.
Actually, the calendar we use is the _Roman Catholic_ calendar - or the Gregorian Calendar. The names of some months *are* Roman and 3 weekdays. The rest is a bit of a hodge-podge. en.wikipedia.org/wiki/Gregorian_calendar
Very nice, thanks.
Mind blown! WOW!
fabulous!
I have watched this more than I can I can remember. I knew about the calendar back untill Gregory times but now it's refreshing to go far back as to it's origin. The first king of Rome kingdom in 731BC.
Thank U so much 💓👍⏳⌚⏲️⏱️🕗🌒🌞
The fact that we still use September/October/etc., but for the months 9-12, just goes to show how much humans have a habit for hacking systems together on top of older, flawed systems. We do this everywhere if you look hard enough.
A 'brief' history?
Triple like smash.
What about the jubilee calendar ?
Nature has and always will disrupt man made models. This is the power point I took away from this observational discussion, because anyone who has lived any length of so called time knows that change is a constant, and why models are reformulated at a feeble attempt to compensate for the unknown variables nature puzzles science with.
I agree with you David.

Well stated!! Yeah!
Man merely attempts to rebel against nature and what 'God' has ordained.
If Science was understood to become important around 450 AD, it was too late to realise it. On the contrary, the Eastern calendars that originated in India for almost 1000s of years earlier were very scientific with absolutely no selfish names to months or weeks. The world needs to know that every name was associated with nature and every year in a cycle of 60 years also have unique names.
Many were copy of roman calenders.
It is an interesting narrative but as a trained historian I have some difficulty accepting Romulus as an existing historical figure. On Roman religion you can read my grandfather's La Religione Romana (G.B. Pighi) supplemented by more modern research.
I'm glad to see that I'm not the only one that researches for fun. Thank you for mentioning the 8th day that got lost when the Pope assigned Sunday as the day of worship. Nobody mentions that so not many people know the 8th day ever existed. People celebrated twice because people were sticking to ancient traditions. I still believe we are out of alignment. Winner is always later every year in Florida. Winter was November when I was a child. Now it's February March.
Also in FL, and yes, the seasons are changing and shifting a little each year. I have not been able to come up with a calculation for it, but I do believe it has something to do with the calendar changes. We're not tracking years and the seasons of each year properly in the present day and I haven't been able to pinpoint a single cause. It's a mess to unravel!!!
Wow I'm glad I'm not the only one who spotted this as well.
Thought I was crazy!
Not global warming? the season is off by calender inaccuracy
Thanks for the truth of lunar calendar . HalleluYah.

baseless
Lecture had some factual errors. Romulus and Numa are legendary figures who may or may not have existed. So it's far from certain they had anything to do with the Roman calendar. Also, the notion that August had an extra day added to match July is generally believed to be a myth. The seven day cycle named after the first hour's planet was around well before Constantine. Dennis the Small (actually Dionysius Exiguus) did NOT invent the concept of 'BC' and 'AD'. He merely computed a table of Easter dates in which he numbered the years from the nativity of Jesus. It was a later scholar, the Venerable Bede who introduced the 'BC' concept in his historical writings. While it was known that spring equinox was falling several days before March 21 centuries before the Gregorian reform, the statement that it led to Christians being mocked seems a bit much.
C M Good points. Where can we watch *your* video?
nepentewhatever bad point, where can we watch your bad louzy video ?
What is the address to your video, audio, written explanation of the facts about calendation? I am researching the original YAH given calendar of sun, moon and stars from day four of creation and question what parts of YAH's calendar does Judaism, Catholicism, Islam, or Protestant Christianity have correct?

Nice going. Very well presented. I wonder would a glass of wine have lasted as long as that water though.
Thanks a lot.
We are moving around the sun??
The sun moves. It rises and follows the analema till it sets out of perspective..
Wait, if the gregorian calendar subtracted 10 days from the Julian calendar, which was about 365.25 days in a year, then whats the explanation for why the gregorian calendar has 365.2425 days in a year?
365.24667days is the length of the year. The .24667 days is slightly short of a quarter day. The Julian calendar address that extra fraction of a day by adding a leap day every four years to compensate for that extra quarter day per year. However it is a slight over correction. To address this problem Pope Gregory brought the calendar back in sync with the seasons by subtracting the ten day drift. Then to prevent the extra three day drift per four hundred year period he dictated that years divisible by 100 but not 400 will not be leap years. For example, the year 2000 was a leap year but 2100,2200,and 2300 will not be leap years. Even though 1896 and 1904 were leap years, 1900 was not. This happens to also be an overcorrection but the drift is so small that it will be thousands of years before it will be further modified.Perhaps the .2425 is the result of the four hundred year rule I described above.
10 days were not subtracted from a standard year every year. 10 days were skipped only once to re-synchronize.

And command you the children of Yashar'el that they observe the years according to this reckoning 👉three hundred and sixty four days, and these will constitute a complete year 👈, and they will not disturb its time from its days and from its feasts; for everything will fall out in them according to their testimony, and they will not leave out any day nor disturb any feasts. But if they do neglect and do not observe them according to his commandment, then they will disturb all their seasons and the years will be dislodged from this order, and they will disturb the seasons and the years will be dislodged and they will neglect their ordinances. And all the children of Yashar'el will forget and will not find the path of the years, and will forget the New Moons, and seasons, and Shabbaths and they will go wrong as to all the order of the years. For I know and from henceforth will I declare it unto you, and it is not of my own devising; for the cepher lies written before me, and on the heavenly tablets the division of days is ordained, lest they forget the feasts of the covenant and walk according to the feasts of the other nations after their error and after their ignorance. 👉For there will be those who will assuredly make observations of the moon how it disturbs the seasons and comes in from year to year ten days too soon. For this reason the years will come upon them when they will disturb the order, and make an abominable day the day of testimony, and an unclean day a feast day, and they will confound all the days, the holy with the unclean, and the unclean day with the holy; for they will go wrong as to the months and Shabbaths and feasts and jubilees.
👉For this reason I command and testify to you that you may testify to them; for after your death your children will disturb them, so that they will not make the year three hundred and sixty four days ONLY, and for this reason they will go wrong as to the New Moons and seasons and Shabbaths and feasts, and they will eat all kinds of blood with all kinds of flesh.

Guess I'm not the only one who noticed that she picks up the cup every now and then and keeps it back again without drinking from it. Lol
Babylonian calendar is base on moon whether Egyptian calendar is based on sun booth predates roman, julian, gregorian calendar. Lunar calendar is far more sophisticated they dont have problem like the solar calendar use to have. Its simple you see the new moon that marks the beginning of new month. But determining a month by position of sun is relatively insane. They excuse season but seasons are adversre in northen & southern hemisphere relative to sun that just make no sense. Whether lunar calendar doesnt affected by these phenomenon. Season is not importan in lunar calendar. Come to cultivation people till to date does not plant on any particular day rather they have their own sense & signs to do so. Modern standerd time is still very young (1884).

So we are older than we are?
not really correct to say they didn't have fractions. No they didn't have decimal-fractions (0.75) , but they did have whole number fractions such a 3/4 means 3 divided by 4, is three-quarter, 3 of 4. They prove this when they do things like roll a one-cubit stone radius to get length that we then think was a ruler of pi.
I have a question since you are a physics field. Why does my satellite clock and my manual car clock have to adjusted to match the time on my cell phone. This has be a reoccurring problem for years
