Seen some complex answers here.  Let's keep it dead simple.  Use the
datetime module to do the heavy lifting.  Go to IDLE, write this.

import datetime.

Then start to write this:

difference = datetime.date(

and at that point IDLE will tell you to put in year,month,day.  That's
convenient.  Do as IDLE asks, obey IDLE!  Wind up with this (put date
later in history first, here are two I've used):

difference = datetime.date(2007,9,25) - datetime.date(1970,12,25)
print difference

13419 days, 0:00:00

Hey now!  Date math!  Yeah!
