Why can’t I have two birthdays listed on the same date?

Hi hudis100,


Thanks for the report, but this actually works as expected — you can have multiple people’s birthdays listed on the same date. I just tested it myself and confirmed it:


https://www.hebcal.com/yahrzeit/edit/01m0r2aps88teecmme9vx1jj1a


Both Person1 and Person2 show up correctly as separate entries on 10 Feb 2026 (23rd of Sh’vat), and again in every subsequent year (5787, 5788, etc.). So there’s no bug here — the calendar handles overlapping dates fine.


If you’re still running into an issue, could you share the exact steps you took and what you saw (a screenshot would help), so we can pin down what’s different in your case?


Best, Michael

I put in 7/23/2026 and expected Tishah B'av (9 Av), but converted it to 10 Av instead.

      Problem with this page https://www.hebcal.com/holidays/?i=on

      Kim 4 weeks ago updated by Michael J. Radwin 4 weeks ago 1

      This page did not switch over to the Israel calendar. You can see that there are two days for holidays...please let me know when you fix it. Thanks for your awesome site!https://www.hebcal.com/holidays/?i=on

      Hi Kim,

      Thanks so much for the kind words and for flagging this! I checked, and the page is actually working correctly — it did switch to the Israel calendar.

      The reason it looks similar to the Diaspora list is that Passover in Israel is 7 days (one day of Yom Tov at the start, one at the end), while outside Israel it’s 8 days (two days of Yom Tov at the start and end). So for 2027:

      Israel: Apr 22 (1st day), Apr 23–27 (Chol HaMoed), Apr 28 (last day)

      Diaspora: Apr 22–23 (1st two days), Apr 24–27 (Chol HaMoed), Apr 28–29 (last two days)

      The “Apr 21” date you see is Erev Pesach (the eve), not an extra festival day.

      Let me know if anything still looks off — happy to dig further!

      @hebcal/core JS library license

      Justin S 1 month ago updated by Michael J. Radwin 1 month ago 1

      I am using the @hebcal/core library in a project that I would like to open source, but I would also like to use Drizzle ORM (licensed under Apache-2.0, not compatible with GPL-2). I am curious if there is an "or later" clause that would allow me to open source this project under AGPLv3, which allows me to use Apache-2.0 licensed products? Thank you!

      The Alexa Hebcal skill hasn't worked for months.

      izzy 1 month ago updated by Michael J. Radwin 1 week ago 4

      When I try to use Hebcal on Alexa, it says "I'm having trouble accessing your Hebcal skill right now"

      This has been going on for months.

      I have 

      Rebooted
      Disabled and re-enabled
      REbooted 
      davened

      Nothing changes.

      Did you try it out? It looks like Alexa Plus has made some changes and it might work for you. We just tested on both a standard Alexa and Alexa Plus device and we’re able to get the Hebcal skill to work again. 

      Shabbat shalom and Shana Tova!

      Thanks for writing in. Sunday 27 September 2026 is 16 Tishrei 5787 — the second day of Sukkot. (Sukkot begins at sundown on the 25th, with the first day falling on Saturday the 26th.)


      The reason it's marked is that Hebcal defaults to the Diaspora calendar, where the second day of a festival is observed as Yom Tov Sheni shel Galuyot. This is a rabbinic practice rather than a Torah one, and it originated in the era when the new month was declared by witnesses in Jerusalem and communities far from the Land couldn't be certain which day had been fixed — so they kept two. It was retained by rabbinic decree even after the calendar became mathematically fixed.


      In the Land of Israel, 16 Tishrei is not a festival day at all — it's Chol HaMoed, an intermediate day of Sukkot. If you'd prefer a calendar that reflects that, you can switch to the Israel schedule on our custom calendar page, and 27 September will show as Chol HaMoed rather than a festival day.


      To be clear about what Hebcal is: we're a calendar that reflects how the Jewish calendar is observed in practice, and we don't take a position on questions of scriptural interpretation. The Israel/Diaspora setting is there precisely because observance differs, and we'd rather give you the option than decide for you.

      Outlook for mac calendar does not show hebrew dates

      Eyal Bitansky 2 months ago updated by Michael J. Radwin 2 months ago 3

      The Hebcal Calendar version on the web shows Hebrew dates in Hebrew letters, but when converting to ICS, only events and holidays are shown with Hebrew dates, and the dates for the other days are missing. See images:

      One image is the Web Version with Hebrew Dates, and the second image is a screenshot from MacBook Outlook Calendar showing only holidays but no Hebrew dates.

      Thanks for the screenshots — that makes the difference clear.


      What you're seeing on hebcal.com is our fully Hebrew calendar view, which we added in December 2025. It uses Hebrew months as the primary structure and shows Gregorian dates as secondary annotations. That layout only exists in our web view and in the printable PDF output, because it requires a calendar grid built around Hebrew months.


      ICS (iCalendar) feeds can't reproduce that. The iCalendar standard is Gregorian-only — every event has a Gregorian start date, and there's no way to express "this month is Tammuz" to a calendar app. Outlook (and Google Calendar, Apple Calendar, etc.) only render a Gregorian grid, so a subscribed feed can never invert into Hebrew months. That's a limitation of the format and the calendar apps, not of the feed itself.


      The closest equivalent in Outlook is to have every day carry its Hebrew date as an event. On the custom calendar page, switch back to the Gregorian layout and check "Hebrew date every day of the year" (rather than "for dates with some event", which is what your current feed appears to use — that's why only holidays show a Hebrew date). Regenerate the feed and re-subscribe, and you'll get a Hebrew date entry on all 365 days alongside the holidays.


      If your goal is a fully Hebrew month layout you can actually look at, the printable PDF from the web view is the way to get that today.


      Hope that helps — let us know if the regenerated feed doesn't come through correctly.

      How can erase the word ‘Parsha’ before the parsha?

      hillelmandel 2 months ago updated by Michael J. Radwin 2 months ago 1

      Michael J. Radwin 2 months ago

      Hi Hillel,


      Thanks for reaching out, and sorry for the frustration! Unfortunately, we don't currently offer a built-in way to customize or edit event titles (such as removing the word "Parsha") in the calendars we generate.

      That said, there is a manual workaround if you're comfortable editing files on a computer:

      1. Download your calendar as an .ics file by following steps 1–7 of our Google Calendar alternative instructions. This will save an .ics file to your computer instead of subscribing to a live feed.
      2. Edit the .ics file in a plain text editor. Each event has a SUMMARY: line — you can edit that line to change how the title appears (for example, changing "Parsha Bereshit" to just "Bereshit").
      3. Import the edited file into your calendar program by following steps 8–19 of the same instructions (creating a separate calendar in Google Calendar and importing the file).

      One important thing to note: if you download, edit, and import the file this way, you'll be working with a static copy of the calendar rather than a live, perpetual feed. That means:

      • You won't automatically get future years' events added
      • Any updates or corrections we make on our end won't reach your calendar
      • You'd need to repeat this process periodically if you want future dates

      If you'd rather keep the live, auto-updating subscription, you'll need to keep the default event titles as they are.

      Let us know if you have any questions along the way!

      Shabbat shalom,

      Michael
