By popular demand, we’ve added Pesach Sheni, a minor holiday that comes every year on the 14th of Iyyar, one month after Passover.
We have also added Erev Purim and Erev Tish’a B’Av dates to the Hebcal calendar on the days prior to Purim and Tish’a B’Av. Previously the “Erev” dates were only displayed for major yom tov holidays, but both of these holidays have significant evening-time congregational events associated with them.
Jewish holiday download support for Outlook 2011 for Mac OS X has been added to the hebcal.com website. See our download and import instructions for more details.
Beginning with Hebcal for Unix 3.9, Asara B’Tevet is allowed to fall on a Friday. This is a significant bugfix.
According to http://www.ou.org/chagim/roshchodesh/tevet/fast.htm
If a public fast occurs on Erev Shabbat, we fast the entire day till the conclusion of the fast, even though it means entering Shabbat while fasting. Neither “Avinu Malkeinu” nor “Tachanun” are recited at Mincha.Â The fast continues until after the completion of Maariv for Shabbat (after the appearance of the stars).Â One should not eat or drink anything until after Kiddush.
Nowadays our calendar calculation is such that the only public fast which can fall on Erev Shabbat is the tenth of Tevet.
Older versions of hebcal incorrectly moved a Friday Asara b’Tevet fast to Thursday. We apologize for the inconvenience.
After 8 years, we’ve finally redesigned the Hebcal.com website to be a little more modern-looking and easier to navigate with a menu on every page. We’re also using the WordPress content management system to manage our help pages and other content.
We hope you like the new look. If you see anything broken, let us know.
Developers: the hebcal for Unix source code is now stored in a Mercurial repository, hosted by sourceforget.net. You can browse the hebcal hg repository.
(Previously the source code had been stored in a CVS repository, also on sf.net.)
