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, or years are between two dates, what date is plus or minus any number of days 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, 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.
