Tishrei 5783 updates

We’ve released a few minor improvements to the Hebcal website during the past month.


Birkat HaChama is a rare Jewish blessing recited once every 28 years thanking G-d for creating the sun. The holiday will occur next on Wednesday, 8 April 2037.

Purim Meshulash, or three-fold Purim, is a rare calendric occurrence that affects how Purim is observed in Jerusalem. When Shushan Purim (Adar 15) falls on the Sabbath, the holiday is celebrated over a period of three days.

Shushan Purim Katan is a minor Purim celebration during Adar I on leap years observed in Jerusalem and walled cities.

Daf Yomi in Hebrew is now displayed with the page number in gematriya (e.g. כתובות דף פ״ג) instead of Arabic numerals (e.g. כתובות 83)

Legacy CSV export of non-English calendar files now open more reliably in Microsoft Excel on Windows 10 and Windows 11 due to addition of a UTF-8 Byte Order Mark at the beginning of the file.
