In addition to providing details about the weekly Torah readings, Hebcal makes it convenient to listen to the audio of a professional cantor chanting Torah trope.

If you visit the Hebcal parsha pages from a larger display (desktop/laptop computer or a tablet), you can click the speaker icon to visit Sefaria‘s embedded PocketTorah audio.


The Sefaria native mobile app does not currently support the PocketTorah audio, so the Hebcal speaker icons are not displayed on mobile phones. The audio is displayed only on Sefaria website and depends on a larger screen, such as a desktop/laptop computer or a tablet.

Please add credit to the two Jewish authors behind the Hebcal algorithms

Tomer 2 years ago updated by Michael J. Radwin 2 years ago 1

The Hebcal UNIX program was a C reimplementation of the calendar code found in the Emacs text editor. That was written by Prof. Edward Reingold, who wrote a book on calendar algorithms with Nahum Dershowitz. I think it would be showing kavod to include both their names under the "About" page on Hebcal.org, as they are the ones who contributed the core technology. Here is a page with more information:

Thanks for the suggestion. We updated our "about Hebcal" page as follows

Hebcal was created in 1992 by Danny Sadinoff as a Unix/Linux program, derived in large part from the Emacs 19 calendar routines by Edward M. Reingold and Nachum Dershowitz.

Parshat Chukat : Triennial Cycle

david scaduto 2 years ago updated by Michael J. Radwin 2 years ago 1

Are the readings for Parshat Chukat correct the triennial cycle, Year 2? I see that there was a mistake in the original planning document that was later correct on Hebcal, but I wonder if perhaps this was overlooked. The kriyah for Year 2 is shown as beginning at the beginning of the full parasha, which I don’t believe is correct.

Thanks for your careful attention to Hebcal's Torah readings. We can confirm that yes, the readings are 100% correct.


The pattern for Chukat-Balak for the current 3-year cycle is Together-Separate-Separate. This maps to Variation C in A Complete Triennial System for Reading the Torah published by the Committee on Jewish Law and Standards of the Rabbinical Assembly, 1988. Here is the relevant excerpt from the 1988 paper:

Yes, there is a document called Modification of the Triennial Cycle Readings for Combined Parashot in Certain Years written by Rabbi Miles B. Cohen, 2020. However, this responsa applies to Variation A, not Variation C.

Lastly, the Miles Cohen luach agrees with both Hebcal and the conservative responsa:


Shabbat shalom!

Viewing or amending pre-2020 Hebcal dates

Debra 2 years ago updated by Michael J. Radwin 2 years ago 2

Hi,

I uploaded my yahrzeits in 2019 but now I need to amend/add to my list. I spent considerable tie collating them and would need to start again from scratch if I deleted the current Hebcal in my Google calendar. Is there any way of seeing the hebrew dates so that I don't have to start again?

Hebrew title for a recurring birthday event

amitai glauber 2 years ago updated 2 years ago 10

Currently, you allow creating a recurring Hebrew birthday event. But you force the user to accept the title you give with the text "'s 19th Hebrew Birthday". I don't like it because it is displayed on my device from left to right, and also because it is an English title when all the events in my Google calendar are in Hebrew. Can you give the option to choose the text, or at least choose whether the text will be in Hebrew or English?

If you subscribed to annual email reminders, you can search for an existing Yahrzeit + Anniversary Calendar by email address here:

https://www.hebcal.com/yahrzeit/search


If you did not subscribe by email, but you created a Yahrzeit list and then subscribed in your calendar app (e.g. Apple, Google, Microsoft Outlook, etc), then you can follow instructions on this page:

Day information slightly lacking.

pjacobson 2 years ago updated by Michael J. Radwin 2 years ago 2

Hi, this is a brilliant website. One suggestion: more information about current day. When I go to Hebcal, I want to know the parsha and whether there's anything addition like shabbat mvarchin. Today is shabbat mvarchin but it is not mentioned. I have to look at Rosh Chodesh list, manually to find out when it is.

We have added Mevarchim Chodesh when it occurs to the homepage and Hebrew Date Converter

January 2026 is missing

tova 2 years ago updated by Michael J. Radwin 2 years ago 1

Trying to create the calendar for 2026 but it starts from Feb.  January is missing

Answer
Michael J. Radwin 2 years ago

Hi, thanks for using Hebcal.

If there are no events in a month at the beginning or end of a year, the month will appear blank. This can happen in January, for example, when you adjust th calendar settings to disable Rosh Chodesh.

If you wish to see January 2026, be sure to have the Rosh Chodesh and/or Special Shabbatot box checked as follows:

You have an excellent "custom calendar" generator that has a square for every day of the year. It would be great if the entries from my "yartzeit list", also on this website, can be included in my custom calendar. Thanks for a great product!

Thanks for the suggestion. To merge a Jewish holiday calendar and a personal Yahrzeit/Anniversary calendar into the same view, we recommend importing your Hebcal events into a separate calendar app.

We provide step-by-step instructions for importing into Apple, Google, Outlook and other calendar apps.
