Can you send us a private message to mradwin@hebcal.com with the download.hebcal.com URL that you subscribed to in Google Calendar? We may be able to assist in the data migration and move this to an editable calendar for you

Also, please note the &yto=on option as specified on the Jewish Calendar API documentation.

Thanks, this is helpful. יום השנה seems much more generic because it could also be used for an anniversary, such as a wedding anniversary?

What about יום פטירתו? This is something a friend in Israel suggested.

We're going to experiment with יאָרצײַט for now, and are really open to other suggestions, especially if there are good sources you can point us to.

We're working on adjusting the title of the event to be in Hebrew if the name specified contains Hebrew characters. Here's an example of what we're experimenting with

יאָרצײַט ה-28 של פלוני (י״ג חשון)

There seem to be differing opinions about whether the event should be called יארצייט, ום השנה, נחלה, or even יום פטירתו

I am not a Hebrew speaker - so I could use a bit of guidance here. Do you have a recommendation? 

We've begun implementing this and would like your recommendation for how to pick good titles for these calendar events. I am not a Hebrew speaker so I'm making some guesses.

Here is a possible rendering of a yahrzeit for an event with the person name סבא רבא

נחלה ה-24 של סבא רבא (י״ג חשון)
And similar rendering for a birthday for a person name of אִמָא
יום הולדת ה-50 של אִמָא (ט״ז שבט)

Should we specify יום הולדת עברי instead of just יום הולדת to make it clear that the birthday is based on the Hebrew calendar and not the Gregorian calendar?

Is של סבא רבא better than לסבא רבא ?

If you wish to use the Israel holiday schedule (and not the Diaspora, which is the default), use &i=on per the documentation. In Israel there is only one day of Yom tov for Shavuot, so there will be no "Shavuot II" event.

Thanks for the suggestion. We can investigate doing some simple analysis of the text and change the English to Hebrew if we detect Hebrew characters in the name.

In the meantime, of you edit the calendar and choose "other" type, the algorithm will use the birthday rules but will not display the year number or "Hebrew Birthday"

Please note that the "other" type is not recommended for Yahrzeit because the rules are a bit more complicated for Yahrzeits occuring in Adar, Cheshvan and Kislev

Thanks for sharing! Very cool!

We have added Mevarchim Chodesh when it occurs to the homepage and Hebrew Date Converter

Thanks for the excellent feedback! We agree that we should list Mevarchim Chodesh more prominently. We'll add this to the to-do list!
