Hi, thanks for using Hebcal.

If you're a JavaScript developer, the most flexible way to generate Jewish holiday and Hebrew date events is to use the @hebcal/core npm package. https://www.npmjs.com/package/@hebcal/core

We also offer many different web developer APIs that you can use via JavaScript or any programming language

Best of luck!

Hi, thanks for using the Hebcal Hebrew/Gregorian date converter.

https://www.hebcal.com/converter?gd=17&gm=3&gy=1968&g2h=1

Sun, 17 March 1968 (before sunset) = 17th of Adar, 5728

Hebrew year 5728 was not a leap year (note month: Adar).

Since Hebrew Year 5728 was not a leap year, our converter page displays "Adar" as there is no ambiguity about the month of Adar in a non-leap year.

Hi, thanks for using Hebcal's triennial Torah Reading feature.

In December 2021 we updated our Triennial readings to reflect the November 2020 responsa from the CJLS which modified the 3rd year readings for a half-dozen parshiyot. We published a short note about this change on the Hebcal.com website here:

https://www.hebcal.com/home/3824/triennial-torah-reading-revision

Since you reference Yad LaTorah from 2002, this obviously was published before the November 2020 CJLS responsa. So Yad LaTorah was correct at the time it was published, but it has become out-of-date.

Hi, thanks for using Hebcal and our yahrzeit email reminder service.

You'll find an "edit Yahrzeit" link next to the "Unsubscribe link" at the bottom of every Yahrzeit email reminder message like the following:

Yahrzeit reminder email messages come from Hebcal and have a subject like "Yahrzeit Observance for October 20-21"

If for some reason you can't find the Yahrzeit message, please send an email to mradwin@hebcal.com and we'll look your email address up in our database and get you the right link.

Hi, thanks for writing to the Hebcal Jewish Calendar support page.

We don't conduct Shabbat services - we're just an online calendar resource.

Hebcal (pronounced HEEB-kal, as in Hebrew calendar) is a free Jewish calendar and holiday web site.

Our mission is to increase awareness of Jewish holidays and to help Jews to be observant of the mitzvot.

We offer a powerful custom Jewish calendar tool that lets you generate a list of Jewish holidays for any year (past, present or future). Also available are a Hebrew date converter, Shabbat candle lighting times and Torah readings (both full kriyah and triennial system), and a page to look up yahrzeits, birthdays and anniversaries.
