Hi, thanks for using Hebcal!

To get Shabbos/Yom Tov times for your city, visit our custom calendar creator at https://www.hebcal.com/hebcal

Check the various holiday/event options you want, and then type the name of your city in the "Candle-lighting & Fast times" box, and then pick from the drop-down list. See screen-shot below.

Then, click Create Calendar.

Then, you'll be able to click the Download button and select your calendar app (Outlook, Google Calendar, Apple, etc)

Understood. And yes, you're correct that this is a bug. Any date conversion between Gregorian and Hebrew calendars involving dates prior to the year 1752 C.E. (Hebrew year 5512) or earlier is guaranteed to be inaccurate.

Hebcal does not take into account a correction of eleven days that was introduced by Pope Gregory XIII known as the Gregorian Reformation. Wednesday, 2 September 1752, was followed by Thursday, 14 September 1752.

This has been a known issue with Hebcal for 30 years, and we haven't yet found the time to fix the bug.

If you're a programmer, we'd welcome a pull request. 

You could either start with Go implementation of Hebcal (look at the FromRD/ToRD functions)

https://github.com/hebcal/hdate/blob/main/hdate.go

Or with the ECMAScript/JavaScript implementation (look at functions abs2hebrew and hebrew2abs) 

https://github.com/hebcal/hebcal-es6/blob/main/src/hdate0.js

We've added a calendar feed for the Vilna Edition. Can you take a look and let us know what you think?

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.
