The Date Calculator is a MacOS X application for many date and time calculations useful to genealogists. It is free if you are a registered user of GEDitCOM II. For others you can get it at the Mac App store (coming soon) or you can click Buy Now below to order here.

The Date Calculator has the following capabilities and more:

Acknolwedgement: Date Calculator uses the date conversion utilities written by Scott E. Lee. He has written a Date Convertor Web Site that converts precise dates between Gregorian, Julian, and Hebrew calendars. He has also posted an excellent Calendar Overview about those calendars. Most of his overview is included (with permission) in the Date Calculator help.

 

Downloads

If you are a registered user of GEDitCOM II the lastest version of Date Calculator is included in your download of GEDitCOM II. The first time you run it, enter your GEDitCOM II unlocking code and you are all set up.

For those not registered for GEDitCOM II, Date Calculator is available as a standalone app. To download Date Calculator, click a link in the following table. Most users should pick the lastest version (or the first line in the table). The others are Legacy downloads that are only needed if the first one does not work in your MacOS. The downloads are a 100% functional version, but will ask for an unlocking code every time it starts. Hopefully you will want to eliminate that message by purchasing a license and entering the code you will get.
