Candle-lighting times for 200+ world cities

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.

 

hebcal for Unix source code moved to Github

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.

Yom HaShoah errata: begins on Sun, 7 April 2013 at sundown

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.
