Working with dates

Our cat is supposed to receive medicine every day for 60 days and then every other day, starting April 7. Working in Python:
>>> import datetime
>>> start = datetime.date(2008, 4, 7)
>>> d = start + datetime.timedelta(days=60)
>>> d
datetime.date(2008, 6, 6)
>>> d.ctime()
'Fri Jun 6 00:00:00 2008'
