Follow these instructions if you no longer wish to subscribe to Hebcal in Apple iCal on your desktop (also called Calendar.app on more recent versions of Mac OS X).

(If you inadvertently merged the Hebcal calendar events with your personal calendar and you didn’t use the Subscription feature, use our delete Hebcal merged events instructions instead.)

Deleting a calendar subscription is easy, and it removes the entire calendar and all the events it contains from your computer.

  1. Select the Hebcal calendar you want to delete in the calendar list on the left side of iCal.
  2. Choose Edit > Delete.

Here’s an example screenshot:

Hebcal.com offers a REST API for fetching Jewish calendar data. The output format is in JSON.

The basic URL format is as follows:

http://www.hebcal.com/hebcal/?v=1&cfg=json&maj=on&min=on&mod=on&nx=on&year=now&month=x&ss=on&mf=on&c=on&geo=geoname&geonameid=3448439&m=50&s=on

Note the following customizable parameters and their meanings:

  • year=now – “now” for current year, or 4-digit YYYY such as 2003
  • month=x – “x” for entire Gregorian year, or use a numeric month (1=January, 6=June, etc.)
  • maj=on – Major holidays
  • min=on – Minor holidays (Tu BiShvat, Lag B’Omer, …)
  • nx=on – Rosh Chodesh
  • mf=on – Minor fasts (Ta’anit Esther, Tzom Gedaliah, …)
  • ss=on – Special Shabbatot (Shabbat Shekalim, Zachor, …)
  • mod=on – Modern holidays (Yom HaShoah, Yom HaAtzma’ut, …)
  • s=on – Parashat ha-Shavuah on Saturday
    • i=off – Diaspora sedra scheme
    • i=on – Israel sedra scheme
  • c=on – Candle lighting times. See also candle-lighting options below.
    • m=50 – Havdalah 50 minutes after sundown. Set to m=0 (zero) to disable Havdalah times
    • b=18 – Candle-lighting time minutes before sunset
  • D=on – Hebrew date for dates with some event
  • d=on – Hebrew date for entire date range
  • o=on – Days of the Omer

Note mutually exclusive location for candle-lighting times:

  • geo=none – no candle-lighting location (default)
  • geo=geoname – location specified by GeoNames.org numeric ID
    • requires additional parameter geonameid=3448439
    • Hebcal.com supports approximately 47,000 different GeoNames IDs. These are cities with a population of 5000+. See cities5000.zip from http://download.geonames.org/export/dump/.
  • geo=zip – location specified by United States ZIP code
    • requires additional parameter zip=90210
  • geo=city – location specified by one of the Hebcal.com legacy city identifiers
    • requires additional parameter city=GB-London
  • geo=pos – location specified by latitude, longitude, and timezone. Requires additional 7 parameters:
    • ladeg=[0-90] – latitude degrees
    • lamin=[0-60] – latitude minutes
    • ladir={n,s} – latitude direction (North or South)
    • lodeg=[0-180] – longitude degrees
    • lomin=[0-60] -longitude minutes
    • lodir={e,w} -longitude direction (East or West)
    • tzid=TimezoneIdentifier (See List of tz database time zones)

Note mutually exclusive language parameter:

  • lg=s – Sephardic transliterations
  • lg=sh – Sephardic translit. + Hebrew
  • lg=a – Ashkenazis transliterations
  • lg=ah – Ashkenazis translit. + Hebrew
  • lg=h – Hebrew only

Note also an optional callback parameter:

  • callback=function – wraps the JSON output text in parentheses and a function name of your choosing. Callback function names may only use upper and lowercase alphabetic characters (A-Z, a-z), numbers (0-9), the period (.), the underscore (_).

And example output looks like this:

If you don’t want candle lighting times, just use c=off and omit the zip and m parameters.

We’re pleased to offer Jewish holiday downloads for BlackBerry devices through a two step process that sends Hebcal data first to Google Calendar, and then to your BlackBerry.

Note that Hebcal is not an app for BlackBerry (in the BlackBerry App World sense of apps that you install). Rather, Hebcal is a website that allows you to download/export calendar data to the calendar application that comes natively with your device.

1. Follow our Google Calendar Jewish holidays download instructions.

2. Then, follow these instructions depending on whether you use the Google Apps for Work (enterprise) + BB10 or regular Google + BB5, BB6 or BB7:

Google Apps for Work users use Google Sync for BlackBerry, which uses ActiveSync to sync with Google Apps. See Set Up Google Sync for BlackBerry 10 for more details.

Non-enterprise Google users with BlackBerry 5, 6, or 7 can use BlackBerry® Internet Service (BIS), which is part of the standard BlackBerry service plan to sync Gmail, Google Calendar, and Contacts with their BlackBerry. BIS is provided by RIM and mobile carriers. BlackBerry offers this guidance on syncing Calendar. Please contact RIM or your carrier for more information and support.

  3. Click the Download… button
    Jewish_Calendar_2014_Providence___Hebcal_Jewish_Calendar

To avoid storing sensitive user data on our servers, Hebcal.com recently modified our Yahrzeit + Anniversary calendar export to “download” instead of “subscribe” calendars. This change affects Yahrzeit + Anniversary calendars created on Hebcal beginning in January 2014, and it applies across iOS, Mac Desktop, Microsoft Outlook, etc.

To make changes like adding a new Yahrzeit or removing one depends on when you downloaded your data from Hebcal.

  • If you “subscribed” to a Yahrzeit + Anniversary calendar (before Jan 2014), delete/unsubscribe from the calendar. Return to Hebcal.com and re-enter in all of the data, then download again.
  • If you “downloaded” (Jan 2014 and later), then any Yahrzeit or Anniversary reminders are now part of your regular calendar (often called “Home” or “Calendar”). To add new events, just go to Hebcal.com and create reminders and download again. To remove events, search for the event(s) in your regular calendar and simply remove them.

Note that this recent change does not apply to regular holiday calendars. Those still offer the “subscribe” functionality.

We’ve made changes to candle-lighting times for Shabbat and holidays that corrects an error we introduced a few months ago. Please accept our sincere apologies for this error.

Candle-lighting times have been adjusted 1-2 minutes earlier and now correctly reflect the correct time to light candles (40 minutes before sundown in Jerusalem, 18 minutes before sundown anywhere else).

Users who subscribe to Hebcal.com calendars via iPhone/iPad, Google Calendar, or Outlook.com should get the corrected candle-lighting times automatically when these applications perform their next refresh. The typical refresh cycle is approximately once a week.

If you downloaded or printed a calendar in the past, you may wish to return to the Hebcal.com website to download and/or print an updated calendar.

The error was caused when Hebcal.com moved to a new sunset calculation engine in the summer of 2013. The new sunset engine allows support for thousands of global cities and fixed long-standing issues with our handling of Daylight Saving Time outside of the USA. Sunset times are estimated from latitude and longitude, and generally have an accuracy of +/- 2 minutes except at extreme north or south latitudes.

Unfortunately, an arithmetic error in determining sunset for a given latitude/longitude was inadvertently introduced, which added an additional 1-2 minutes of error. This error was recently discovered and corrected.

We are pleased to announce that Hebcal.com now supports Daf Yomi. Now you can use Hebcal to help follow your daily regimen of learning the Talmud!

For example, today’s Daf Yomi is Yoma 52.

Just check the new “Daf Yomi” checkbox on the “Include Events” section of our Custom Calendar. We’ve also posted a simple iCalendar feed for those of you who want to subscribe in Google Calendar or Apple Calendar and track the events with a separate color.

Many thanks to Aaron Peromsik for doing the work to add this feature.
