Answer 1

Since you are looking for mathematical formula , it will help you to find a solution to your problem. Let Y be the year,M be the month and D be the day. Do this calculation for both the dates.

Total = Y* 365 + M*30 + D ,then find the difference between 2 totals of the corresponding dates.

While multiplying 30 with M value ,you have to give the number of days in that month. You can do it with #define value or if loop. Similarly you can do for leap year too by multiplying 366 with Y .

Hope this will help u....
