In general, Jewish Holidays begin the evening before the date specified. This is because the Jewish day actually begins at sundown on the previous night. Sometimes, for clarity, the Erev holiday is also included to indicate that the holiday begins the evening before.

For example, in the April 2015 calendar below, Erev Pesach is listed as April 3rd and the first day of Pesach is listed as April 4th. This means that the holiday of Pesach begins on the evening on April 3rd.

And, Rosh Chodesh Iyyar is listed on April 19. This means that Rosh Chodesh begins on the evening of April 18, even though the Erev is not explicitly mentioned on the calendar.

To display a Jewish calendar on your website, you can use event data from Hebcal.com and the open source JavaScript event calendar from fullcalendar.io.

First, you’ll want to start by including the CSS and JS in your header, per the FullCalendar Basic Usage.

Then, for the events configuration, use a url that references our Jewish calendar REST API, but change cfg=json to cfg=fc. For best performance, be sure to use cache: true.

Here’s the FullCalendar invocation:

We recommend some specific styles to make the page look prettier:

Here’s a complete example that uses the aforementioned JS + CSS, and also includes the necessary stuff to load FullCalendar.io and dependencies via CDN:

Hebcal offers a way to specify candle-lighting times location by latitude and longitude for remote or less-populated areas.

Hebcal supports already over 45,000 world cities. Just search for the name of any world city with population 5,000+. However, if you can’t find what you’re looking for in our location database, here’s how you could find candle-lighting times for a specific location.

Example: Ixiamas, Bolivia.

  1. Go to the Getty Thesaurus of Geographic Names at http://www.getty.edu/research/tools/vocabulary/tgn/
  2. Type “Ixiamas” in the Find box and click “Search” button
  3. Click on the link that says “Ixiamas… inhabited place”
  4. Note the latitude/longitude represented in “degrees minutes direction” (in the example of Ixiamas, La Paz, Bolivia it is Lat: 13 45 S and Long: 068 10 W) and write this information down on a sheet of paper
  5. Visit the Hebcal Custom Calendar latitude/longitude page at http://www.hebcal.com/hebcal/?c=on;geo=pos
  6. Type the latitude and longitude into the form (13 degrees, 45 minutes South Latitude, 68 degrees 10 minutes West Longitude)
  7. Select the Time zone option specific to your location (see Wikipedia’s List of tz database time zones)
  8. Click “Get Calendar” button at the bottom of the form
