We recommend looking at the FullCalendar.io examples and documents as they have excellent documentation and a large community. I personally prefer the fetch function (referenced above) instead of ajax libraries like suoeragent or axios. Again, consult the FullCalendar docs and just follow their examples.

Yes it's very easy to add additional events in addition to the Hebcal feed. Follow the FullCalendar documentation and use the eventSources feature to add additional source with your organization's events

An internet search turns up HebCalVb6, a VB6/VBA module to demonstrate how to convert a Hebrew date into the Gregorian date. It can be used within Visual Basic or within a Excel Macro.

      Hi, it has been a couple of weeks and the Google Calendar cache appears to have cleared by now. We have checked and can confirm that Google Calendar is displaying this feed through December 31, 2024.

      Excellent. Glad this helped. Good luck!

      Glad you got it working!

      Our API tries to be very open when it comes to CORS. We always include Access-Control-Allow-Origin: * in the response when the cfg parameter is set to json.


      No authentication or authorization is required to use our API. It is accessible to a wide range of users without restrictions.

        We've added a new script without nikkud

        <script src="https://www.hebcal.com/etc/hdate-he-v2.js"></script>

        Confirmed that 365 days will fit in the Google Calendar feed limit. We pushed out a change, and depending on Google's caching it may take between 1-7 days before you see the refreshed year-long feed updated on Google Calendar.
