From Hadley's book. (In case you were wondering, “POSIXct” stands for “Portable Operating System Interface”, calendar time)

Hey Kelly
I have the date column => 19/02/2001, and it is a character class. How can I convert it to Feb 2001?
Thank you

[@SuperKrazy2000]

If you use
dat %>%
mutate(
date = lubridate::dmy(date)
)
Your column will be understood as a datetime object. If you wanted to bring it back to a String, but just say "Feb 2001", I'd do this:
library(lubridate)
dat %>%
mutate(
date = dmy(date),
date_string = paste(month(date), year(date)
)

Many thanks for thi vids ! But I need help, how can I generate semester variable using an other date variable ?

[@SuperKrazy2000]

As in, you'd like to make a variable marking the semester as "Fall", "Spring" or "None"?
I'd do this:
dat %>%
mutate(
semester = case_when(
month(date) < 5 ~ "Spring",
month(date) > 8 ~ "Fall" ,
TRUE ~ "Summer"
)
)
