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

Days until Christmas:

>>> import datetime
>>> today = datetime.date.today()
>>> someday = datetime.date(2008, 12, 25)
>>> diff = someday - today
>>> diff.days
86
