How to increment a datetime by one day?

date = datetime.datetime(2003,8,1,12,4,5)
for i in range(5): 
    date += datetime.timedelta(days=1)
    print(date) 

Incrementing dates can be accomplished using timedelta objects:

import datetime

datetime.datetime.now() + datetime.timedelta(days=1)

Look up timedelta objects in the Python docs: http://docs.python.org/library/datetime.html
