Hi, thanks for contacting us.

There is a C command-line interface (not a library). It is not designed to be used in a library context (global variables, places where the code calls die() or exit()) but you are welcome to take a look. 

To find the older C code, go back in the GitHub repository to the latest 4.x release

Thanks for using Hebcal, and thanks for the feedback! We disabled the ArrowLeft/ArrowRight navigation on the Hebrew Date Converter as we agree it doesn't work well on a web page that has interactive forms.

Thanks for using the Hebcal Leyning API!

We don't have a centralized list of all of the parsha and holiday names, it's scattered in a few different places.

The English & Hebrew names of the regular parshiyot are included here in this JSON file:

https://github.com/hebcal/hebcal-leyning/blob/main/src/aliyot.json

Note that for regular parashat haShavua, we return a numerical field called parshaNum which can be used as a mapping key which may be more convenient than using the name field. Bereshit = 1, Noach = 2, etc.

The names used for holiday readings in English transliteration (such as Sukkot I) are included here:

https://github.com/hebcal/hebcal-leyning/blob/main/src/holiday-readings.json

And if you want Hebrew equivalents of the holiday names (such as סוּכּוֹת א׳), you will find them here:

https://github.com/hebcal/hebcal-es6/blob/main/po/he.po

Please let us know if this helps, and good luck with the API!

Thanks for your reply. We can see from the screen shot that you're using the App Store on an iPhone, not the App Store on the Watch itself.

Because our app is Apple Watch Only and doesn't have an iPhone companion app, trying to install a 2nd time via the iPhone app store won't work. (Bad user experience on Apple's part to show you a greyed-out Purchased button, but it's a bit understandable because Watch-only apps are relatively new. I'm hoping Apple will probably eventually fix this.)

The recommended workaround is to install the Hebcal app from the App Store on the watch itself.

Press the Digital Crown to see the Home screen, then tap the App Store.

Then tap the Search box at the top, type Hebcal, and tap the Search button on the top right.

Then follow the instructions we posted earlier.

Thanks for the feedback. Moved them above the advertisement.

Hi, thanks for using Hebcal. We're sorry to hear that you're having difficulty editing a Yahrzeit date.

Based on the information you provided, it sounds like you created your Yahrzeit calendar subscription sometime before August 2020.

If you subscribed before August 2020, you will need to delete or unsubscribe the calendar containing your yahrzeit and anniversary reminders. Hebcal personal event calendars created before this date do not support editing event dates or names. Directions for how to delete/remove a subscribed calendar vary by calendar application.

For more information, you can read this article on Hebcal.com

Hi, thanks for using Hebcal and thanks for your question about mincha leyning.

We added holiday Mincha to our Leyning spreadsheet downloads in September 2022. If you have an old CSV file, perhaps you can go back to the Hebcal website and download a current file?

Here's an excerpt from the current CSV files:
