This is a page devoted to Hebcal, a Perpetual jewish calendar program

What is it? Hebcal is a C program that I wrote in College. The key routines are translations of Dershowitz & Reingold's lisp code in GNU-Emacs 18. Hebcal offers several convenience routines that make it a good fit for generating calendars for PDAs and personal calendars.

Hebcal has been successfully ported to Perl, C, and Javascript, but I'm currently only maintaining the C implementation. Java is likely to be the next supported platform.

Sourceforge now hosts new development.
