The Gregorian calendar is the usual Time / Date referential for western cultures. It is used since 1582 and specifies correctly the leap years in order to compensate the earth revolution time around the sun (a year is a leap year if it is multiple of 4, but not multiple of 100 except if it is also a multiple of 400).
This implementation is inspired from the free software source code there: http://waysysweb.com/COM/Waysys/util/WayDate.txt
