How do I credit Hebcal in my code?
I'm writing a custom Salesforce integration and would like to callout to the API for date conversions, birthdates, yarzheits, etc. Is there a paid version of the API? Either way, is there a line I can include to properly credit you?
Hebcal Salesforce integration sounds great!
There is no paid API. You are welcome to use Hebcal freely.
Here is some guidance in how to give credit to Hebcal

Thanks for using Hebcal!
To create a calendar with Israeli schedule, visit our custom calendar page at https://www.hebcal.com/hebcal and choose the "Israel holiday schedule" option instead of Diaspora, and make sure Rosh Chodesh is checked.
To enable alerts for Rosh Chodesh and other holidays, download/subscribe to the Hebcal calendar in your favorite calendar app. Go to the app settings and enable the option to alert on all-day/untimed events (see below for an example from the Apple calendar; there are similar settings in Outlook, Google Calendar, and other calendar apps).
Zmanim calculation with elevation
Hi
I'm using this API https://www.npmjs.com/package/@hebcal/core
I want to know if there is a way to add elevation in addition to lat, long coordinates for zmanim calculation
Thanks
Hi, thanks for using the Hebcal JavaScript library.
Zmanim, Candle-lighting and Havdalah times are derived from sunset times, which are approximated from a location (latitude, longitude) and day of year. There is no way to include elevation in the Hebcal zmanim calculations because the underlying solar calculation algorithm doesn't use elevation.
The NOAA solar algorithm claims accuracy within 2 minutes except at extreme northern or southern latitudes. Adding elevation often changes the sunset calculation by 1 minute or less, so this is within the expected margin of error.
Triennial reading of Parashat Devarim: I suspect an error
Triennial reading of Parashat Devarim: I suspect that there is an error in the third Aliyah - should it not be Psukim 8-11, rather than Psukim 8-10? There isn't even a "star" after the 10th pasuk. On the other hand, the שני marker in תיקון קוראים starts at Pasuk 12.
Hi, thanks for using Hebcal. We double-checked and the triennial divisions as published are indeed correct. The third triennial aliyah should be 1:8-10.
Our triennial aliyot divisions correspond with both the CJLS triennial divisions and the traditional full kriyah aliyot divions (the first full kriyah aliyah ends at verse 10).
For an explanation for why the aliyah concludes with verse 10, see below excerpt from the 5783 Luah Hashanah by Rabbi Miles Cohen (highlighting mine)
Can we no longer download a csv file for candle lighting times?
I no longer see this as an option in the download lists and I have been doing it for years.
UK Reform triennial
Hebcal currently presents the American Conservative triennial as the only triennial. In fact, you have to go deep into Hebcal to even find the triennial is from the Rabbinical Assembly: https://www.hebcal.com/home/50/what-is-the-triennial-torah-reading-cycle
However, the UK Reform movement has been using its own triennial for some time, and the current cycle is published at https://www.reformjudaism.org.uk/wp-content/uploads/2021/05/Calendar-of-Torah-and-Haftarah-Readings-5782-5784.pdf
It would be great if Hebcal could display alternatives, or at least be clear there are alternatives.
Thanks.
