Hi, thanks for contacting us!

The Hebcal website and APIs support 13 different languages for event titles. By default, Hebcal uses Sephardic transliterations. To transliterate event titles in a different language, specify lg=LANG parameter using one of the following values listed on this page.

https://www.hebcal.com/home/4534/jewish-calendar-event-language-support

If you're seeing Ashkenazic transliterations, this means that your site is using lg=a or possibly a very old  a=on  API parameter.

Change to  lg=s   and remove any occurrences of  a=on  and you'll be all set!

If you used Hebcal to create your personal calendar after August 2020 and you subscribed using the recommended feed option, you can click on the hebcal.com URL at the bottom of any calendar event in the feed to make changes or add additional names.

Visiting that link will take you back to the Yahrzeit and Anniversary calendar where you can make edits to each person's name or dates. You can also use that link to add additional names and dates to the same calendar.

After making changes on the Hebcal.com website, you do not need to resubscribe to the calendar feed in Google Calendar. Any changes you make on the Hebcal.com website will automatically be updated in the calendar feed and show up in your 3rd party calendar app, typically about 24 hours after the change is made on the Hebcal.com site.

If it's been more than 48 hours and you still don't see changes reflected in the Google Calendar, please send your private Hebcal calendar URL to mradwin@hebcal.com and we can investigate further. You'll find your personal URL in your email confirmation message, or at the bottom of any yahrzeit event that is already showing up in Google Calendar.

For further instructions please read

Thanks for your message. What you're seeing in iOS 26 is a feature of Apple's operating system and not something that Hebcal.com controls.

If you don't wish to see the Hebrew date in Hebrew, you can disable the Hebrew calendar on iOS 26 following Apple's instructions:

Change how your calendar is displayed

You can customize the way your calendar is displayed to help highlight the information that’s most important to you. For example, you can choose which day you want to start the week with, display the Chinese, Hebrew, or Hijri calendar (alongside the Gregorian calendar), and more.

1. Go to the Settings app on your iPhone.
2. Tap Apps, then tap Calendar.
3. Do any of the following:
   • Display the Chinese, Hebrew, or Hijri calendar: Tap Alternate Calendars, then choose a calendar.
   • Display the week number next to every week of the year: Turn on Week Numbers.
   • Show the current day as the first day in Week view: Turn on Week View Starts On Today.
   • Choose a different day to start the week: Tap Start Week On, then tap a day.

Thanks for the bug report. Fixed!

After some testing the past week, we have confirmed this is an issue on Outlook.com. There is no way to force Outlook to refresh a calendar subscription, and for some reason it has stopped refreshing many of the Hebcal calendar feeds.

We have confirmed that if you unsubscribe from a Hebcal calendar in Outlook Web and then re-subscribe, the problem resolves itself immediately and you will see the events in Outlook.com in a matter of seconds. I hope this approach will work for you too!

G'mar Chatima Tova!

Thanks for pasting the URL - this helps us understand the calendar settings you're using.

Your calendar subscription is a 2-year perpetual calendar feed with events for the current year (5785) plus 1 future year.  We've confirmed that the feed contains events starting October 2024 (Rosh Hashana 5785) and ends in September 2026 (Erev Rosh Hashana 5787).

However, we subscribed to this exact calendar feed on Outlook Web and we see exactly the issue you are describing. For some reason Outlook is not fetching all of the events in the feed.

We're going to keep investigating, but in the interim we have a recommended workaround: unsubscribe from this calendar feed and use multiple Hebcal.com calendar subscriptions.

For example, if you’d like to include the Hebrew date for every day of the year, you can subscribe to that calendar via a separate calendar feed at our Jewish Holiday downloads page. Look for Hebrew calendar dates (English) or Hebrew calendar dates (Hebrew).

We have an article that explains why calendar apps like Outlook.com impose size limits on individual calendar feeds, and how multiple calendar feeds avoids this problem

https://www.hebcal.com/home/1398/number-of-years-in-calendar-feed-subscriptions

An added advantage of the multi-subscription approach is that you can choose separate colors in Google Calendar or iOS/iCloud calendar for each calendar event feed.

Sorry to hear you are having difficulty with this! Sounds frustrating and we hope we can help. 

Can you share the exact download.hebcal.com URL with us so we can inspect the server side?

Are you following these Outlook.com Jewish holidays download instructions? or are you using the more generic iCalendar/ICS Jewish holidays download instructions?

Thanks for your message.

We have confirmed that our Jewish Holidays (only major holidays) feed contains only major holidays such as Rosh Hashana, Yom Kippur, Passover, Hanukkah. That feed does NOT include minor & modern holidays, fast days or Rosh Chodesh.

We offer a separate Jewish Holidays (all holidays)  feed which contains major, minor, modern Israeli holidays, fast days and more.

You can subscribe any of these specialized feeds at https://www.hebcal.com/ical/

We note that you mention "Gedaliah Fast" and not "Tzom Gedaliah". Some non-Hebcal holiday feed providers (for example Google Calendar itself) use the event title "Gedaliah Fast". If you're seeing that event title and not "Tzom Gedaliah" then it suggests that you didn't subscribe via Hebcal.com. For the fast of Gedaliah, only use the title "Tzom Gedaliah"

Thanks for the suggestion. We appreciate this input and will consult some other sources to see if this proposal aligns with other calendars.

Shana Tova!

Thank you for the bug report. We have fixed the issue with Hebrew not rendering correctly on the Hebcal website.

We're terribly sorry for the inconvenience
