Havdallah times on Google calendar are wrong - one week behind

Scott S. 4 years ago updated by Michael J. Radwin 4 years ago 5

I live in Simi Valley, CA, 93065, and I use the hebcal calendar through Google calendar. The havdallah times listed on Saturdays have been off by about 10 or 11 minutes each week when compared with Chabad.org 's zmanim times. Please advise.

Answer

If you'd like to customize Havdalah calculations in Google Calendar, our recommendation is to remove/unsubscribe the entire calendar, and then to download/subscribe from Hebcal again with the new settings.


Here are instructions to remove Hebcal events from Google calendar:

Candle lighting times in Maale Adumim

Moshe Raab 4 years ago updated by Michael J. Radwin 4 years ago 1

I love this site and application, Thank you very much for creating and maintaining it.

I would like to point out that in Maale Adumim we start Shabbat like in Yerushalayim (and Petach Tikva), i.e. 40 minutes before shkia.

Is there a way to adjust for that?

Hebcal.com app for androids?

grampygreg 4 years ago updated by Michael J. Radwin 4 years ago 1

Is there an app for hebcal.com for androids? I searched Google Play Store and didn't see it. There were many others but nowhere as good and inclusive as the web version.

Thanks so much for the suggestion. No official Android app currently but we hope to make one in the coming year.

In the meantime, you can export Hebcal calendar events to Googld Calendar and then your Android device will see the events.

Candle Lighting Times

I have used hebcal for decades on GNU/Linux and also on thunderbird. It
has been accurate and rock solid.  I decided I needed to update the
thunderbird calander and the new calander, both as generated on the
website and the download is off on candlighting time by about 3 minutes,
and Havdalah, I have really no idea what is happening.  The commandline
seems correct to 72 minutes

Another update: after a bunch of research, we've come to the conclusion that the sunset algorithm we were using in the JavaScript version of Hebcal wasn't accurate enough. As of today, we have swapped it out for a version that although less-commonly used in the JS world, seems to match both the previous C version and most other sources.

Some of the Hebcal event feeds are cached up to 1 week, so subscriptions on Google Calendar, iPhone, etc might not refresh until next Sunday.

To make a change to a Yahrzeit + Anniversary calendar calendar, delete or unsubscribe from the calendar. Return to Hebcal.com and re-enter in all of the event details, then download again. Hebcal does not yet support editing event dates.
