Suppose you were born in New York, then the time of birth is recorded to the nearest minute. Since you can now be in a different time zone, you should explicitly specify the time zone:

>>> import pendulum # $ pip install pendulum >>> birthtime = pendulum.create(1999, 9, 11, 23, 10, tz='America/New_York') >>> age = pendulum.now() - birthtime >>> age.in_seconds() 569173149
  • And if born in Vasyuki, then the time of birth is not recorded to the minute? ;-) - Kromster
  • @Kromster: on the birth certificates I only see the day. - jfs
  • Why put a minus answer? Answer the mean cowardly;) - jfs
  • So in the question only the date appears. In general, the curtsy towards watches / belts / minutes is not very clear. not minus - Kromster
  • @Kromster: the answer to the question "how to calculate the difference in seconds" must take into account time zones. If it is not clear, then you can read more on the link, I quoted above - jfs

Import datetime, it has such a function as timedelta, which calculates the difference.

    naive subtraction without taking into account the time zone, can make a avoidable error in the calculations (for the birthday it may not matter, but in the general case it is advisable not to introduce hourly errors when subtracting time). - jfs
