Announcing the first release of Daf, my Daf Yomi calendar calculator for Palm OS. Its been tested on the Tungsten T2, the Palm TX, and the Palm m515; it should work on any PalmOS 3.5 or later unit.
From the README:
Daf is a perpetual Daf Yomi calendar. Daf Yomi is a learning program whereby you learn a "daf" or folio of the Babylonian Talmud each day. The cycle completes in about seven and a half years. Daf Yomi was started in 1923 by Rabbi Mair Shapiro. You can read more about it at the Wikipedia entry.
Daf is a _perpetual_ calendar, which means that it will tell you the daf for just about any day you want. Unliked other calendars that only tell you the schedule for the current cycle, Daf lets you truly plan ahead.
Daf is free under the terms of the GPLv2.
There are links on the sidebar to the .zip and .tar.gz files. Each contain the prc file, source code, a README, and a handy copy of the GPL.
