Shorter the Hebrew Dates

Gilad 7 months ago updated 7 months ago 2

Firstly, thank you very much for the wonderful Hebrew Calendar. Ofter many searchs i found yours and its the best!! Thanks!

Now, if i can suggest, if its possible to shorten the Hebrew date. Instead of - כז חשוון התשפב, to write just - כז חשוון for example...

Maybe it can be in the setting of the calendar and anyone who want to tick that option will can.

This is the only negative i can find in your wonderful work. Thank you again and hope my suggestion is doable 🙂

Hi, thanks for using Hebcal and thanks for posting this suggestion!

We've changed our calendars so we only include the year in the Hebrew date for the 1st of Tishrei (e.g. Rosh Hashana).


Please go back to how it was: start date of holidays

Adam Kahn 9 months ago updated 9 months ago 4

First of all, you created a wonderful and useful website.

Seems recently that you start holiday dates with night before. Very confusing. People (including myself) are used to seeing the start date as the full secular day; we already know it starts the night before. I understand that it may be confusing for the non-regularly-observant. 


Example for 21-22: Rosh Hashanah Sep 6‑8 M‑W. At first sight seems that it is 3 days long! Please revert to how it was before. Thank you.

Hi Adam, thanks for using Hebcal and thanks for the feedback.

Our mission at is to increase awareness of Jewish holidays and to help Jews to be observant of the mitzvot.

Some of the users of are observant Jews and some users of Hebcal are gentiles who want to be aware of when Jewish holidays are so they can be respectful of their Jewish friends, colleagues and classmates.

Many of the users who visit our Jewish Holidays summary page need to know exactly when a holiday begins. That it why each holiday summary page includes the following text at the top of the page:

Except for minor fasts, holidays begin at sundown on the date specified in the tables below. For example, if the dates for Rosh Hashana are listed as Sep 6-Sep 8, then the holiday begins at sundown on Sep 6 and ends at nightfall on Sep 8.

We have learned over many years that for observant Jews, adding the "Erev" before the holiday is the best way to clarify when a holiday begins in an evening, and indeed our calendar includes Erev for all major holidays and even for some minor ones like Purim. Observant Jews also will know that Rosh Hashana is only 2 days long and not three.

Oftentimes visualizing the dates on a calendar grid can help to clarify further, especially in combination with the Erev. See below for an example:








Erev Rosh Hashana


Rosh Hashana 5782


Rosh Hashana II


Tzom Gedaliah



Shabbat Shuva





Erev Yom Kippur


Yom Kippur





Erev Sukkot


Sukkot I


Sukkot II


Sukkot III (CH''M)


Sukkot IV (CH''M)


Sukkot V (CH''M)


Sukkot VI (CH''M)


Sukkot VII (Hoshana Raba)


Shmini Atzeret


Simchat Torah



How to calculate the number of days between two dates on the Jewish calendar.

tomajo jmt 11 months ago updated by Michael J. Radwin 10 months ago 1

Hi, I would like to make a suggestion. It would be interesting to have a way to calculate the number of days between two dates on the Jewish calendar. I study biblical prophecies and we often need to know this information.

I would be immensely grateful.


Shavuot wrong dates

ronmar 1 year ago updated by Michael J. Radwin 11 months ago 3


First of all, thank you for this great API/data!

Second, I saw that there is Shavuot I (17.05.2021) and Shavuot II (18.05.2021) in the API as I'm a jew and living in Israel I don't know anything about these two, Shavuot is a two days holiday, there is only Shavuot Eve (Erev Shavuot 16.05.2021) and Shavuot (17.05.2021).

here is a picture from google to confirm it:

Michael J. Radwin 11 months ago

Hi, thanks for using Hebcal.

For Israel this is the URL we publish which shows only one day for Shavuot

Which says: Shavuot (Festival of Weeks) for Hebrew Year 5782 begins in 🇮🇱 at sundown on Saturday, 4 June 2022 and ends at nightfall on Sunday, 5 June 2022.

And for Diaspora (chutz l'aretz) we publish this page

Which says: Shavuot (Festival of Weeks) for Hebrew Year 5782 begins in the Diaspora at sundown on Saturday, 4 June 2022 and ends at nightfall on Monday, 6 June 2022.

I hope this extra location information helps.


Hebrew Date Converter REST API not showing Omer

Mike Feingold 1 year ago updated by Michael J. Radwin 10 months ago 3

I'm using the Converter REST API.

According to the documentation (here, near the bottom of the page) this should return the day of the Omer.

However when I try it ( then no Omer event is returned in the Events section.

Am I missing something?


Yahrzeit dates from Jewish calendar REST API

tZkSs 1 year ago updated by Michael J. Radwin 1 year ago 2

Is there a way to get Yahrzeit dates from Jewish calendar REST API

I need to get next anniversary dates by looking at date of death a person. 

I tried to find the solution on Hebcal site, they are provided a REST API for calendar, and UI to calculate that dates also, but I could not to find REST api method for it

this is the UI,

I need that data as JSON from REST API.

If anyone have experience on that please let know me


Michael J. Radwin 1 year ago

We've released some experimental support for an API here.

Documentation is forthcoming, but the basic idea is that you'll need to POST x-www-form-urlencoded data to with the special parameter cfg=json

For example:

curl '' \
-H 'content-type: application/x-www-form-urlencoded' \
--data-raw 'cfg=json&n1=Example1&t1=Birthday&d1=15&m1=4&y1=1983&s1=on&n2=Example2&t2=Yahrzeit&d2=13&m2=11&y2=2008&s2=off&hebdate=on&years=20&v=yahrzeit' \


Shabbat Hanukkah maftir - only one prince

Josh Greenfield 1 year ago 0

The Hanukkah Torah reading for weekdays (per Ashkenazic custom outside of Israel) is two days of the princes bringing offerings from the section of Numbers 7 (e.g., on day 3 of Hanukkah we read of the prince who brought offerings on day 3), plus the prince who brought offerings on day 4).  On Shabbat of Hanukkah (when not also Rosh Hodesh) we read the regular Torah reading for 7 aliyot, and the maftir reading is just one prince, corresponding to that day of Hanukkah (e.g., if Shabbat is day 3 we read of the prince from day 3 only). right now is showing that the Shabbat of Hanukkah this year we read from Numbers 7:18-29, which is two princes:

I'm guessing the algorithm is just using the weekday Hanukkah custom to figure out what the Shabbat maftir reading should be, but that seems to be incorrect.  For the source of the Hanukkah reading, you can check Shulkhan Aruch OH 684:2 (note 6 in the Mishnah Berurah specifies only one prince in the maftir).


Yom Kippur Katan

nsuffin 2 years ago updated by Michael J. Radwin 10 months ago 2

With all of the different dates currently included in Hebcal, would it be possible to please also add Yom Kippur Katan?

Michael J. Radwin 10 months ago

Update: we've added a Yom Kippur Katan calendar feed to the Hebcal website. You can find it towards the bottom of the Jewish holiday downloads page.

Yom Kippur Katan

יוֹם כִּפּוּר קָטָן is a minor day of atonement occurring monthly on the day preceeding each Rosh Chodesh.
9 calendar events per year. 10-year perpetual feed.

Yom Kippur Katan is omitted in Elul (on the day before Rosh Hashanah), Tishrei (Yom Kippur has just passed), Kislev (due to Chanukah) or Nisan (fasting not permitted during Nisan). When Rosh Chodesh occurs on Shabbat or Sunday, Yom Kippur Katan is observed on the preceding Thursday. [1]

Complete set of candle lighting times for a chag

Rachel 2 years ago updated by Michael J. Radwin 9 months ago 1

I would greatly appreciate your sending a complete set of candle lighting and Havdalah times for a chag BEFORE the chag begins. 

I looked up the times for the last 2 days of Pesach at another site during chol hamoed, so I could post them on my kitchen cabinet IN ADVANCE. 

I was sent the times via HebCal AFTER the 7th day had already started (east coast USA) which was not helpful. 

This type of issue has happened before, and is very frustrating and disappointing. I appreciate the HebCal email service, but it’s disturbing that the info is incomplete. It also leads me to wonder if the info is reliable, since this type of problem is easily preventable by better planning. 

Michael J. Radwin 9 months ago

Hi, thanks for using Hebcal. We're sorry to hear that our weekly email updates didn't arrive in a timely fashion last year. We've made some changes recently to ensure that doesn't happen again.

We'd also like to encourage you to take a look at our Candle-lighting Times Year at a Glance tool. You can fill out a form to get Shabbat and holiday candle lighting times and Parashat haShavuah (weekly Torah Portion) for the entire year on a single page. You can print it out and post it on your refrigerator.

Shana Tova!
