We typically light candles 18 minutes before sunset in most of the world, but 40 minutes before sunset in Jerusalem.


When you specify Jerusalem using the typical URL in Hebcal, you get the special 40-minutes-before-sundown feature automatically.


If you are going to specify candle-lighting times with our API by latitude, longitude and time zone and you want to specify 40 minutes before sundown for Jerusalem, be sure to specify b=40 in the URL (overriding the default b=18).


Yes, you can use the Jewish calendar REST API to get only parashat haShavuah for an entire year like this:


http://www.hebcal.com/hebcal/?v=1&cfg=json&s=on&maj=off&min=off&mod=off&nx=off&year=now&month=x&ss=off&mf=off


The s=on means Parashat haShavuah. The other features (major holidays, minor holidays, etc) are all set to "off"

We hope to release a feature in the future to allow uploading a CSV file to the Yahrzeit calculator. In the meantime you can use this link to enter up to 20 names

Pesach 5776 begins on Fri, 22 April 2016 at sundown (15th of Nisan, 5776)

Thanks for the inquiry. The current API does indicate the special reading for Shabbat Rosh Chodesh for Haftarah, but it does not offer the ability to customize.

Hi, thanks for your message.

Hebcal.com does provide a yahrzeit calculator, but we do not provide any Facebook integration. Is it possible that the Yahrzeit candle app you use is provided by someone else?

Sorry we can't be more helpful.
Hi, thanks for your message.

Unfortunately, we are having trouble reproducing the problem you reported.

We see the header correctly appearing in the output:
