WinDate Calculator is a flexible utility program that allows you to quickly perform date calculations without having to manually thumb thru a calendar. It can work with any dates between September 14, 1752 (the official beginning of the English Gregorian calendar) and December 31, 3999.

If you need help determining how many days/weeks/months/years are between two dates, what date is plus or minus any number of days/weeks/months/years from another date, what day of the week a certain date falls on, or just need a handy calendar reference, WinDate Calculator is your tool of choice.

Features include the ability to define count criteria, mark recurring holidays, perform calculations by days/weeks/months/years, print calculation results, copy/paste dates in a variety of formats, and optionally sit in the Windows system tray.

Site/volume licensing is available. This version is fully functional & can be used for a 30-day trial period.
