Chag HaBanot / Eid al-Banat
I did a search on HebCal and was surprised at the omission of this North African Jewish holiday, which is increasingly observed among Jews globally. Can you please provide a listing and calendar dates for it? So far, what I find online is that it falls on the sixth day of Hanukkah/Rosh Chodesh Tevet. As a holiday that celebrates girls and women, Chag HaBanot is becoming very popular, and also incorporates more Jewish diversity into our calendar. Thank you.
We've added the holiday to our calendar.

Shabbos/Yom Tov times not on Outlook download
In the past downloading the Holidays included Shabbos/Yom Tov start times but they're no longer there. How do I download times?
Hi, thanks for using Hebcal!
To get Shabbos/Yom Tov times for your city, visit our custom calendar creator at https://www.hebcal.com/hebcal
Check the various holiday/event options you want, and then type the name of your city in the "Candle-lighting & Fast times" box, and then pick from the drop-down list. See screen-shot below.
Then, click Create Calendar.
Then, you'll be able to click the Download button and select your calendar app (Outlook, Google Calendar, Apple, etc)
Year of Creation
According to my calculations the first year of creation was -3761.
Year 2022 corresponds to 5782/3.
Year 1 corresponds to 3761/2.
There was no year 0 on the Gregorian Calendar.
Year -1 corresponds to 3760/1.
Since there was no year 0 on the Hebrew Calendar either, I subtract 3759 and find that the Hebrew year 1 corresponded to Gregorian year -3760 but it actually started in -3761.
Why does HebCal return -3759?
Understood. And yes, you're correct that this is a bug. Any date conversion between Gregorian and Hebrew calendars involving dates prior to the year 1752 C.E. (Hebrew year 5512) or earlier is guaranteed to be inaccurate.
Hebcal does not take into account a correction of eleven days that was introduced by Pope Gregory XIII known as the Gregorian Reformation. Wednesday, 2 September 1752, was followed by Thursday, 14 September 1752.
This has been a known issue with Hebcal for 30 years, and we haven't yet found the time to fix the bug.
If you're a programmer, we'd welcome a pull request.
You could either start with Go implementation of Hebcal (look at the FromRD/ToRD functions)
https://github.com/hebcal/hdate/blob/main/hdate.go
Or with the ECMAScript/JavaScript implementation (look at functions abs2hebrew and hebrew2abs)

Using Hebcal for a physical yahrzeit Board
Hello,
In our Synagogue in Amsterdam RAS sjoel - RAS Sjoel we just installed a wooden Yharzeit board. In the small indivual name boards there is a lamp. The idea is that the lamp is switched on 2-3 days before the date and 2-3 after the date switched off. At present we are doing this manually, but we would like to do this automatically.
In the back of the board we can install a kind of relay wich guides the lamps to switch on the gregorian date using the type of tables that are used by Hebcal/
Questions:
- Anybody having experience with this kind of solution ?
- Does anybody know and /or heard of a similar solution
- Is it possible to use the API.
Any advise and help is very welcome.
Thanks
calendar running on Arduino ?
hi.. i'm trying to re-create this item which appears to be have been discontinued jewish desk clock
i was thinking about using an arduino nano with LCD that has hebrew fonts, and an RTC component
i was wondering if i could use your c library, but i'm not sure that's possible.
Hi, thanks for contacting us.
There is a C command-line interface (not a library). It is not designed to be used in a library context (global variables, places where the code calls die() or exit()) but you are welcome to take a look.
To find the older C code, go back in the GitHub repository to the latest 4.x release
In Hebcal, when cursor focus is in an input field, like the year, arrow key should only change position with field, not change the date.
In Hebcal, if the cursor focus is in an input field, like the year, and I hit the arrow key to move the cursor within the field, it change the whole date instead. I.e. forward or back a date. This is not normal web interface behavior. Can you fix this? Thanks!
Thanks for using Hebcal, and thanks for the feedback! We disabled the ArrowLeft/ArrowRight navigation on the Hebrew Date Converter as we agree it doesn't work well on a web page that has interactive forms.
Get a list of all potential returned values of Leyning reading names
Hi,
I am using the Leyning API, then comparing the returned hebrer parasha name to a list I have in Excel.
Is there a way to get all potential returned name?
For example: לך-לך, סוכות א׳
Thanks
Thanks for using the Hebcal Leyning API!
We don't have a centralized list of all of the parsha and holiday names, it's scattered in a few different places.
The English & Hebrew names of the regular parshiyot are included here in this JSON file:
https://github.com/hebcal/hebcal-leyning/blob/main/src/aliyot.json
Note that for regular parashat haShavua, we return a numerical field called parshaNum which can be used as a mapping key which may be more convenient than using the name field. Bereshit = 1, Noach = 2, etc.
The names used for holiday readings in English transliteration (such as Sukkot I) are included here:
https://github.com/hebcal/hebcal-leyning/blob/main/src/holiday-readings.json
And if you want Hebrew equivalents of the holiday names (such as סוּכּוֹת א׳), you will find them here:
https://github.com/hebcal/hebcal-es6/blob/main/po/he.po
Please let us know if this helps, and good luck with the API!
