Thanks for your message!

The Hebrew Date Converter page for Sat, 30 November 2024 correctly lists the Torah portion as Parashat Toldot

If you look at the Parashat Toldot detail page, you will see that indeed it already lists the special Machar Chodesh Haftarah

Hi, thanks for your message. This is pretty easy to calculate using the Hebcal command-line interface. Here's the general idea:

$ hebcal --chag-only -w | egrep -v "(Erev|CH''M|Hoshana)"

4/23/2024 Tue, Pesach I

4/24/2024 Wed, Pesach II

4/29/2024 Mon, Pesach VII

4/30/2024 Tue, Pesach VIII

6/12/2024 Wed, Shavuot I

6/13/2024 Thu, Shavuot II

10/3/2024 Thu, Rosh Hashana 5785

10/4/2024 Fri, Rosh Hashana II

10/12/2024 Sat, Yom Kippur

10/17/2024 Thu, Sukkot I

10/18/2024 Fri, Sukkot II

10/24/2024 Thu, Shmini Atzeret

10/25/2024 Fri, Simchat Torah

Now we need to just count how many times each holiday occurs on Sat or Sun versus another day

$ hebcal --chag-only -w --years 100 2000 | egrep -v "(Erev|CH''M|Hoshana)" | grep "Yom Kippur" | egrep "(Sat|Sun)," | wc -l

32

Here is a summary:

• Rosh Hashana: 58 / 200 chag days on Saturday or Sunday
• Yom Kippur: 32 / 100 days on Saturday or Sunday
• Sukkot: 58 / 200 chag days on Saturday or Sunday
• Pesach: 117 / 400 chag days on Saturday or Sunday
• Shavuot: 56 / 200 chag days on Saturday or Sunday

Note that we used a 100 year window to approximate. Note that has little to do with the 19-year cycle and more to do with the interaction between the Hebrew and Gregorian calendars. See the Jewish-Gregorian calendar correspondence cycle for more details on that. A calculation can be done with 1000 years, yielding similar results.

A similar calculation could be done for Israel if you add the -i flag, and adjust for the Israeli weekend (Friday + Saturday).

Thanks for using Hebcal, and we are sorry to hear you are having difficulty with timezones in Arizona.

Can you please share a bit more information so we can help? What city or ZIP code are you using for Shabbat and holiday candle lighting times? Could you share the URL of the page you are having difficulty with, and if possible, also a screenshot of the incorrect times?

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.

Sukkot for Hebrew Year 5787 begins at sundown on Friday, 25 September 2026 and ends at nightfall on Friday, 2 October 2026.

As you can see from the above table, Sukkot is exactly 7 days long.

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.

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!

Thanks for the catch about ום נישואין. We've changed the rendering of "יום נישואין 50 לאבא ואמא" to be consistent with your suggestion for birthdays.

Thanks again for the continued suggestion that "יום השנה" is better than "יארצייט" - the Wikipedia article is persuasive. My Hebrew comprehension is very poor, but Google Translate gives me a very general sense of what it's trying to say.

I'm going to consult a bit with the Hebcal co-founder Danny (who moved to Israel 25+ years ago) before replacing יארצייט with יום השנה

Thanks, this is all tremendously helpful. I understand that although יום השנה sounds generic to me, it has an implied meaning of יום השנה שנפטר (please forgive my poor Hebrew).

In English, the term "anniversary" is often used for "wedding anniversary", but it has a more neutral meaning - "anniversary" could easily be used for measuring the number of years that you have been employed in the same job, or another momentous day (like the date you became a citizen). Maybe this is because in American culture (outside of Judaism) the anniversary of a day of death is not typically observed.

If Hebcal used יום נישואין for the "Anniversary" type on our calendar, it would probably be correct for most instances - and based on our experimental implementation it would only be used for names that contained Hebrew letters - so this sounds like a good step.
