Hi, thanks for your message, and thanks for using Hebcal!

If you'd like to show US holidays on a calendar alongside Hebcal events, we'd recommend downloading from Hebcal into a calendar application such as Google Calendar, Outlook, or Apple Calendar (on macOS or iOS). 

You'll find instructions on how to download here: https://www.hebcal.com/home/category/import

Hi, thanks for your message. The fact that you only see current year plus future is by design.

If you would like to convert historical dates, please use our date converter tool

not yet. Our current API only supports query by full year or year + month

Thank you for this suggestion. We will consider this feature request for a future version of Hebcal.

Thanks Rabbi Schlesinger!

This is an excellent suggestion. We will consider this feature for a future version of our Yahrzeit calculator.

You can unsubscribe/remove the original calendar and then re-download from Hebcal with the updated options.

No, sorry.
