Yahrzeits of famous rabbis
How can I add the yahrzeits of famous rabbis to my Google calendar? Is there an existing list of them? Thanks

Something I built using your API
I thought you might like to see a project that I built using your API.
I had a user request to notify him of when the New Moon would fall, but on the Hebrew calendar. I already had an app for working out the Moon phase. I used your API to convert that information and display for this month, and next month.

Works very well.
Thank you for making the API available. I would never have been able to do this without that.

regarding creating Yahrzeit Birthday cal
would it be possible to have the Gregorian date as well on the calendar as there are some family members that want to celebrat the Gregorian date and some there hebrew.

Succot 2026
Hi, Succot 2026 seems to be 9 days long - Simchat Torah should finish on 3 October, and Shemini Atzeret should be shifted a day earlier too! https://www.hebcal.com/holidays/2026

Sukkot for Hebrew Year 5787 begins at sundown on Friday, 25 September 2026 and ends at nightfall on Friday, 2 October 2026.
Date | Detail |
---|---|
Friday, Sep 25, 2026 | Erev Sukkot |
Saturday, Sep 26 | Sukkot I |
Sunday, Sep 27 | Sukkot II |
Monday, Sep 28 | Sukkot III (CH’’M) |
Tuesday, Sep 29 | Sukkot IV (CH’’M) |
Wednesday, Sep 30 | Sukkot V (CH’’M) |
Thursday, Oct 1 | Sukkot VI (CH’’M) |
Friday, Oct 2 | Sukkot VII (Hoshana Raba) |
As you can see from the above table, Sukkot is exactly 7 days long.

Shortcut to toggle Dates
Just found a SHortcut to go a day forward or go back in time:
I was at url https://www.hebcal.com/converter?hd=14&hm=Sivan&hy=5784&h2g=1
When I pressed the Key Combination Alt+Arrow-Right, the date of tomorrow was displayed and when I pressed the Key Combination Alt+Arrow-Left, the date of yesterday was displayed.

Fix for HebCal on Android phone not always showing (Google Calendar)
Once installed/added to Google Calendar (via Desktop), HebCal doesn't already appear to display on android mobile phones. It is (sort of) there, however it's not entirely intuitive.
On the Android Google Calendar app you need to go into Menu (the hamburger bar in the top left hand corner), Settings, if you have lots of calendars you need to click on "Show More", click on HebCal and then tick/slide the Sync button.
My top tip/request would be that the above instructions are also added to the "Download" screen on the HebCal website, as per the screenshot below.

I appreciate very much receiving this Yahrzeit reminder. Will this be done every year?
Today I received a Yahrzeit reminder for my son who past away on July 23rd 2021. Will you continue to send reminders.
I am 80 years of age and if you do continue to send reminders, can I add my wife's and my daughter's email address.
Thank you, A Cohen

Yes, if you subscribe to annual email reminders, you will continue to receive reminders each year unless you opt-out or unsubscribe.
To add an additional email address to receive annual anniversary reminders, follow these instructions:

Bar/bat mitzvah calculator
Dear Hebcal team, I would love to have a function, either on your site or code I could put on our synagogue website, where you simply put in the Gregorian date of birth and it gives you the shabbat after 13 (or 12) years and a day later. Does that already exist? If not, would it be easy to create? (If you do it, please have language functions so that it would display in French!) Thank you so much.

Thanks for the suggestion! We don't currently offer such a feature and it would be a great addition.
Chabad does offer this feature on their website

HEBEVENTS returns diaspora event only
When calling the GoogleSheets HEBEVENTS function with the date of May 27th (2023) the result is "Shavuot II", though in Israel this is a regular "Parashat Naso".
I think we better have another parameter saying whether the client needs Israel or diaspora events.
Thank you so much for this service!!
It is unbelievable how useful and helpful it is, for so many Jews around the world.

Hi, shavua tov. The Hebrew Date Converter Google sheets Add-on was built by an independent organization called YML Solutions.
https://workspace.google.com/marketplace/app/hebrew_date_converter/70892373699
This plugin uses the Hebcal APIs but otherwise we aren't affiliated with their product. You will need to contact them directly to ask them to make the change to add an optional Israel boolean parameter to their function.
We are truly sorry we can't help further with this issue.
