Solved Win7 Calculator, week calculation error

[kf10]

when i try to calculate weeks between two dates using win 7 calculator
ie 2nd Feb 2004 to 20 Sep 2013

it says 9 years, 7 months, 2 weeks, 4 days ie 9*52 weeks + 7*4 weeks + 2 weeks = 468 + 28 + 2 = 498 weeks

however it shows that 3518 days have passed during these two dates, which is 3518 / 7 = 502 weeks

what am i missing here

But 7 months is not 28 weeks. It would only be 28 weeks if all months had 28 days equaling 4 weeks exactly but they haven't. What about those with 30 and 31 days. If you physically count on a calendar you will find that 3518 days is correct.
