difference between dates

hi,i want to create 2 dates and find the number of days between them

how do i create 2 dates of the dd/mm/yy format?
then how to find the number of days between them?

appreciate if some-one can give me a example on how to go about doing this.

Thanking you,
Rahul SK

Convert both dates to a time_t, using mktime()
Then work out the difference (in seconds) using difftime().
Seconds to days should be easy from there.
