How to calculate number of days between two given dates?

Question

If I have two dates (ex. \'8/18/2008\' and \'9/26/2008\'), what is the best way to get the number of days between these two dates?

Answer 1

There is also a datetime.toordinal() method that was not mentioned yet:

import datetime
print(datetime.date(2008,9,26).toordinal() - datetime.date(2008,8,18).toordinal())  # 39

https://docs.python.org/3/library/datetime.html#datetime.date.toordinal

date.toordinal()

Return the proleptic Gregorian ordinal of the date, where January 1 of year 1 has ordinal 1. For any date object d, date.fromordinal(d.toordinal()) == d.

Seems well suited for calculating days difference, though not as readable as timedelta.days.
