How to calculate the difference between two dates in C?

The following is a C program to calculate the difference of two dates in years, months and days. Make sure that the start date is earlier than the end date. Enter start date (MM/DD/YYYY): 08/05/2001 Enter end date (MM/DD/YYYY): 08/20/2001 Difference: 0 years 00 months and 15 days.

How to calculate the number of days between two dates?

Firstly, when entering two dates in different years, the output is always off by about one month (31 in most cases, but 32 in one case...go figure). Second, two dates exactly one month apart will return the number of days in the second month (i.e. 1/1/1 to 2/1/1 yields 28).

How do you find the difference between start date and end date?

All we need to do is subtract day, month and year of the start date from the day, month and year of the end date, respectively. Note that here we are assuming that the start date is smaller than the end date and the difference of days, months and years will be positive. However, there is one problem.

Is the first date smaller than the second date?

In this case, the first date is smaller than the second, but the difference in days and months is not positive. If day2 < day1, we borrow a month that is before mon2 and add days in that month to day2.
