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.
We’re now using the Alef Hebrew Font on Hebcal.com.
Alef is an open source multiscript web-font. Here’s an example from our Hebrew Date Converter:

When you update your Apple device to iOS 7, you may need to adjust your Subscribed Calendar settings in order to see your old Hebcal.com calendars.
For some calendars, iOS7 defaults to SSL on, which did not work with Hebcal.com back in September 2013. Since then, we’ve added SSL support to Hebcal, so you shouldn’t have to take any of the following steps. We’re keeping them here mostly for historical purposes.
Resetting the calendar to SSL off will cause the calendar to show up correctly again.
- Launch the Settings app
- Touch “Mail, Contacts, Calendars“
- Touch “Subscribed Calendars“
- Touch the Hebcal calendar(s)
- Under “Subscribed Calendar Information”, set “Use SSL” to “OFF“
If the screen you see next looks like the following, be sure to set the “Use SSL” setting to “OFF”
Update – March 2014: to avoid storing sensitive customer data on our servers, we recently modified our Yahrzeit + Anniversary calendar export to “download” instead of “subscribe” calendars in iOS. Note that this only applies to our Yahrzeit + Anniversary calendar, which often includes names of individuals.
If you successfully downloaded a Yahrzeit calendar from Hebcal.com to your iPhone, then any Yahrzeit or Anniversary reminders are now part of your regular calendar (often called “Home” or “Calendar”) and there is no need to make any changes to your Settings.
Here is how to disable alarms for a Hebcal calendar from your iPhone or iPad so you won’t get an event reminder.
First go to the Settings app, then touch Mail, Contacts, Calendars. Scroll down until you see the Subscribed Calendars item:
Touch Subscribed Calendars to see the list:
Then, touch the Hebcal calendar and turn Remove Alarms to On:
We’re pleased to share that we’ve made some changes to the hebcal website to better accommodate world cities. If you visit our Shabbat Times page, you’ll see hundreds of new cities available for candle-lighting times.
You may notice that candle-lighting times have changed by 1-3 minutes as well. This is due to a change in the sunset calculation algorithm we’ve introduced as well. Sunset times are estimated from latitude and longitude, and generally have an accuracy of +/- 2 minutes except at extreme north or south latitudes. This new algorithm is more accurate than the previous one.
If you’ve been using Hebcal.com to calculate candle-lighting times via latitude and longitude, you might find your city listed in our database. If it’s not there, feel free to drop us a line. If you’d like to continue to specify your location by latitude and longitude, please note that we are now using standard timezone names (such as “America/Chicago” or “Asia/Jerusalem”) instead of GMT offsets + daylight-saving-time rules.
We’re pleased to announce that hebcal for Unix is now hosted on Github. You can find the new repository at https://github.com/hebcal/hebcal
Hebcal for Unix has been around for 20+ years. Danny Sadinoff wrote 98% of the code, and Michael has been fixing bugs and adding features here and there.
SourceForge had been providing hosting for the GPL code for 14+ years. We even converted from CVS to Mercurial about 3 years ago. However, with the recent changes to SourceForge code hosting, Hebcal got stuck in some sort of limbo-land. Lots of 500 Internal Server Errors.
So… we’ve decided to join the cool kids and make the transition from hg to git. And while making that transition we’ve also moved to GitHub, which is where all of the open source developers are hanging out these days.
Over the coming month we’ll be cleaning up the code and the hebcal.com website, removing references to the old sourceforge.net URL.
And then we’ll get back to fixing bugs and adding new features.
We’ve added the Parashat haShavuah to our Year at a glance printable Shabbat times page.
Here’s a preview:
We’re pleased to share that ORT’s Navigating the Bible website has been upgraded to MP3. For many years, Hebcal.com has linked to ORT’s excellent site for Torah readings with Hebrew, translation, transliteration and chanting.
When released 13+ years ago, ORT’s trope/chanting audio was based on a format called RealAudio. Unfortunately, RealAudio doesn’t work very well on modern devices like tablets.
As of May 2013, ORT has upgraded to MP3 – a more modern audio format. Users can listen to individual verses or download whole readings to listen to on their phones, tablets or other mp3 players.
Our sincere thanks to Vladimir Dribinskiy, ORT’s Chief Program Officer, and to the entire World ORT team!
We’ve fixed an error with the observance of Yom HaShoah occurring adjacent to Shabbat. This year Yom HaShoah begins on Sunday, 7 April 2013 at sundown.
Previously Hebcal always used the date of the 27th of Nisan.
When the actual date of Yom Hashoah falls on a Friday, the state of Israel observes Yom Hashoah on the preceding Thursday. When it falls on a Sunday, Yom Hashoah is observed on the following Monday.
