You want to display the Hebrew date at the top of each cell? We have not tried that but you can probably do that with a FullCalendar dayCellContent render hook. This would be a custom JavaScript function you write to convert from Gregorian date to Hebrew date using the HDate class from @hebcal/core.

Hi, thanks for using the Hebcal APIs.

We are sorry we don't understand your question about combining Hebrew dates.

Could you paste a code sample and a screenshot or a URL of your demo explaining better what you see and more detail about what you wish to see?

There is extensive documentation about FullCalendar at their website

Thanks for the suggestion. We don't have the knowledge to be able to compile a list of tzadikim.

You might find a list on another website, for example https://dailyzohar.com/tzadikim/

If you have a list as a CSV file, you can import it into Hebcal using these instructions

We have also finished adding the Hebrew month names to the calendar results page for all languages (not just English)

Fixed the XX problem by removing the Hebrew from PDF (which also shortens the text and makes it fit better on the printed page). It's still in the calendar feed in the description field.

Thanks for the screenshot and the URL. It appears the problem is with Hebrew in the PDF when printing. We'll look into a fix for this.

We're having trouble finding the xx's bug on the Chofetz Chaim calendar. Can you send a screenshot or a URL where you observe the problem?

We've begun the work to add the Hebrew months next to the Gregorian months. It's currently implemented only in English (e.g. Sephardic and Ashkenazic transliterations). We need to do some further work to enable this for Hebrew and other languages (Spanish, German, French, Russian, Polish, etc)

Thanks for the bug report on the Chofetz Chaim calendar. We will investigate.

Regarding displaying Hebrew months at the top, sorry, we don't have that option. Because the website provides Jewish holiday calendars in the context of the Gregorian calendar, the primary way of displaying months is via the Gregorian calendar. We might be able to modify the website so a month display like "February 2023" also displays "Tevet / Sh'vat 5784" next to or under the Gregorian month. Would that help?

Thanks for using Hebcal. Can you send us a photo or a screenshot of what you mean by "the actual month name gets cut off"?

Thank you for the suggestion! We will add this excellent idea to our "to do" list
