This article describes how to make changes to a Yahrzeit + Anniversary calendar that you downloaded, exported or subscribed to in a calendar app like Outlook, Google Calendar / Android, or Apple (iOS, iPhone, iPad or Mac). These instructions apply to personal events such as yahrzeits, Hebrew Birthdays, and Hebrew Anniversaries.
1. I have a Hebcal calendar feed subscription
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 a calendar event. That link will take you back to the Yahrzeit and Anniversary calendar where you can make edits to each person’s name or dates.

If you have previously subscribed to the calendar in a 3rd party calendar such as Apple, Google, or Microsoft Outlook, you do not need to resubscribe. The changes will automatically be updated in the calendar feed, typically about 24 hours after the change is made on the Hebcal.com site.
2. I have a Hebcal annual email reminder subscription
If you subscribed to annual email reminders and did not synchronize your Apple/Google/Outlook calendar, you will find an “Edit Yahrzeit” link at the bottom of the reminder email message.

For a birthday, the link will be titled “Edit Hebrew Birthday.” For an anniversary, the link will be titled “Edit Hebrew Anniversary.”
3. I don’t have a separate calendar feed; I merged Hebcal anniversary events into my regular personal calendar
You may have downloaded yahrzeit/anniversary events and merged them into your regular personal calendar (often called “Home” or “Calendar”). To remove those events, search for the event(s) in your regular calendar and remove/delete them one at a time. These events will always have one of the following titles: “Yahrzeit”, “Hebrew Birthday” or “Hebrew Anniversary”.

Once you have removed the yahrzeit/anniversary calendar events, return to Hebcal.com and re-enter in all of the event details, then download again.
4. I subscribed to a calendar feed before August 2020
If you subscribed before August 2020, you will need to delete or unsubscribe the calendar containing your yahrzeit and anniversary reminders. Hebcal personal event calendars created before this date do not support editing event dates or names. Directions for how to delete/remove a subscribed calendar vary by calendar application.
