Hi tech -- Reminded by the recent email to tech@ about calendar.christian, I took a look at syncing calendar.judaic.
This diff does the following: 1. Sync the holiday days that are not connected to Pesach, which on our calendar is Chanukah, Fast of 10 Tevet, and Yom Yerushalayim. 2. Add the holidays that are explicitly mentioned on the Wikipedia page of Jewish holidays, which adds Tu B'Shevat to our calendar. 3. Replace the year marker on Rosh Hashana with the current Jewish year (5741 => 5779). This calendar has to be updated yearly as it is anyway, so it seems odd to me not to put the current year if we're going to list a year in connection with Rosh Hashanah. It looks like mickey@ removed Yom HaAtzmaut some years ago due to the understanding that this be a religious and not secular calendar. Which is a perfectly legitimate stance, as there is no universal yes or no as to whether or not the Israeli rememberance holidays are religious holidays, both in Israel and in the dispora. So we either need to remove Yom Yerushalayim for the same reason, or add back Yom HaAtzmaut, and add Yom HaShoah and Yom Hazikaron. Doesn't matter to me either way. It might be nice to include Yom HaShoah in either event, as it is likely to become a universal Jewish religious holiday within our lifetimes. Whatever is decided having Yom Yerushalayim by itself is the strangest of all worlds. And I'll volunteer to keep this calendar synced since I might be the only one who cares about it.
