Welcome to, the web site of the GBC Vaisnava Calendar Committee of the International Society for Krishna Consciousness (ISKCON).

We are still under construction here, and not all features are working, but now you are invited to:
  • Register and download the "GCal" program, a full-featured executable for making vaisnava calendar calculations. To register, click "Create an account" in the sidebar. (GCal is now available in both Windows- and Mac-based versions.)
  • Visit our forum and read about calendar calculation-related issues, or if you have something to say, register and participate in the discussions.
Coming soon:
  • Online calculation of customized calendars for any location showing all the days that are important to you, such as your guru's vyasa puja day, family birthdays, anniversaries, etc.
  • Set up email reminders for just the days you want.

More about GCal:

Developed by Gopalapriya Das of ISKCON Bratislava, Slovakia, GCal (for "Gaurabda Calendar") is a full-featured calendar calculation program for Gaudiya Vaisnavas. Choose from the database of thousands of locations, or add your own remote spot! Calculate tithis and naksatras, add custom events that you are interested in observing. Find out sunrise and sunset timings, and lots more.

We would like to express our thanks to all those who have participated in the beta testing of GCal, too numerous to mention.
