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.
