API for today's date returns 404 Not Found error
All the scripts for today's Hebrew date as listed at https://www.hebcal.com/home/40/displaying-todays-hebrew-date-on-your-website return 404 Not Found
That's the following URLs:
https://www.hebcal.com/etc/hdate-he.js
https://www.hebcal.com/etc/hdate-he-v2.js

Thanks for the bug report! We are terribly sorry for this inconvenience.
The issue has been fixed and the URLs work correctly once again.
You should celebrate your birthday every year!
Hebcal uses the anniversary algorithm defined in Calendrical Calculations by Edward M. Reingold and Nachum Dershowitz, which accords with Ashkenazic practice. Reingold and Dershowitz write:
Someone born on the thirtieth day of Marcheshvan, Kislev, or Adar I has his birthday postponed until the first of the following month in years where that day does not occur. [Calendrical Calculations p. 111]
In other words, on years where there is no 30th of Kislev, your birthday is celebrated on the 1st of Tevet.
Anniversary API input based on Hebrew Date
The current API for calculating Yahrzeit anniversaries uses Gregorian dates which requires a sundown setting. Please provide a similar API using Hebrew date input since this is well defined. If I have a Hebew Date and do not know the particulars of the Gregorian date, there can be two possible English dates to input to get the list of anniversaries. The alternative is used Heb ro Greg converter and loop through a number of years which is inconvenient and Hebrew input to get a list of years in one calc would be great.
Thanks for the suggestion. Effective December 2025, we now support Hebrew dates in the Yahrzeit API as an alternative to Gregorian dates:
- hyX=5749 – Hebrew year
- hmX=Kislev – Hebrew month
- hdX=25 – Hebrew day of month
Hebrew month names may be specified in Hebrew (UTF-8) or transliterated using the same technique as on the Hebrew Date Converter REST API.
Please give it a try and let us know how it works for you!

next yahrzeit observance date
using the yahrzeit anniversary api to get a list of observance dates whic hdepends on starting year and number of years. I would like to know if thee is a specific call for next observance date which would take into account today's date english or hebrew and find the first observance after today or today for tht matter. I had some comple logic in one in one script but if there is a simple cal lit would be grea. Eilse I hae to compare the date say the observance for 5786 with 1 returned date and if that is before today redo the call with next years Hebrew date to start.
when using the API, to get the next occurrence, omit the start and end parameters, and specify years=2. Then, in the returned results, examine the date in the first item. If the date is before today, then ignore the first item and use the second item. If the date of the first item is today or later, then the first item is the next upcoming observance.

Secular/American Holiday Dates
Might HebCal offer the option TO ADD American/secular Holidays? I use HebCal extensively ... so it would help to see those alongside the Jewish calendar.

I use your RSS to display Shabbat times and the weekly portion. Previously, the information was in Russian, but now it's in English. Could you please change it so it's in Russian again?
