Thanks for the info. However at some point i didnt get it. Why did you not add the corresponding value of the longitude which is +4 but you did add the minutes of it only? Thanks for the reply
Hi Jimmy, good question. Some people make the correction directly from Greenwhich, using the hours and minutes. By just using the minutes (east or west of the time zone you are observing), it shortens the process and eliminates any confusion about daylight savings time. Thanks!
Hello chris thanks for the reply! I was so eager to to know immediately the answer so i tried to find on others video here on youtube having thoughts that no one might answer my question since the video was years back and luckily i found one. And its the same as what you've said. Thanks a lot i appreciate it!
Im sorry but i got another question. On the computation for sunset how come that its longitude is west but the zone description is +4? Was that a mistake or it was done in purpose to compensate for subtraction of minutes since in 54 west the sun sets earlier than 60 west.
Hi Jimmy, the notation for east/west of Greenwich is sometimes unclear. For instance if you are 4 hours west of Greenwich, some say that is -4, since you have to add 4 hours to get to Greenwich. A lot of the maritime schools use +4 instead. I don't have a good reference for you, sorry. I just know that in all the American maritime exams, it would say something like "your longitude is 63W (+4ZD)..." so you would know how to solve the problem. Hope that helps! -Chris
Thank you for the question, +4Q is the time zone we are observing (4 hours later then Greenwich Mean Time). Everytime we do a problem we need to convert our local time back into Universal (Greenwhich) time.
Clearly understand ! I have something to ask,Is the final answer is in local time or GMT?If that so how can i convert that gmt sunrise to my local time?Pls. Answer me pleaaaasssseee...
Hi Roger, the final time is in local time. If you need to convert from GMT to local, add or subtract the number of hours that corresponds to your zone descriptor. For example, in California, we are ZD +8. Therefore I would need to add 8 hours from my local time to get GMT, or I would need to subtract 8 hours from GMT to get my local time. Thanks!
I must be losing my memories. I don't recall it being pitch black by 5:00 PM as it is now here in Toronto at Nov 18, 2021.
Can you calculate the assmiths of sunrise and sunsets through the years.
So I have a question ❓ what if the phase was at 5° n @ 23' how do you know you divided or multiply ✖️ to get that results

thank you
but what is +4Q ?

you only choose easy lat and long. please use also other coordinates please
Hello, there are other videos on the channel which use intermediate and advanced techniques too!
I have the same compass
am what if your lat. is 13 degrees and 38 min N and long is 12. 3 degrees and 10 min. E
What day and year?
difficult method to understand
Boring
