Hebrew birthdays & yahrzeits

Hebrew Dates

Enter a Hebrew birthday or yahrzeit once and it appears on the correct Gregorian date every year, from sunset to sunset where you are. Free, and a gift to Klal Yisrael.

Add my dates to Google Calendar

Hebrew Dates creates its own calendar in your Google account and writes only there. It cannot see or change your other calendars.

Try the calculations first

No account needed. Nothing is written anywhere.

1. Calculation location

Is this the right place?

This location is a suggestion. Confirm it, or pick a different one above, before these dates go to a calendar.

2. The date

Record type
How do you know the date?

Adar, Adar I and Adar II are offered separately because the choice itself tells Hebrew Dates whether the original year was a leap year. A yahrzeit on 30 Cheshvan or 30 Kislev needs the year.

3. Display mode

How should Hebrew dates appear?

Sunset times are calculated server-side with the NOAA solar algorithm for the selected coordinates, and rendered in that location’s IANA time zone. Hebrew anniversary rules follow the standard calendrical convention (Reingold & Dershowitz). Hebrew Dates provides calendar calculations, not halachic rulings; where customs differ the affected years are flagged rather than decided silently.
