The Python module datetime allows you to calculate the days between two given dates with relative ease. I am using the US date format month/day/year, but you can change that by giving attention to the order of the extracted tuple.
Days between 2 Dates
# find the days between 2 given dates
# tested with Python25 HAB
import datetime as dt
# US format month/day/year
dateStr1 = '7/14/2006'
dateStr2 = '5/1/2007'
m1, d1, y1 = (int(x) for x in dateStr1.split('/'))
m2, d2, y2 = (int(x) for x in dateStr2.split('/'))
date1 = dt.date(y1, m1, d1)
date2 = dt.date(y2, m2, d2)
dateDiff = date2 - date1
print 'Difference in days = %d' % dateDiff.days # 291 Be a part of the DaniWeb community
