Calendar not syncing to Outlook Web
I've generated the calendar I want in Hebcal, but when I enter the link in Outlook Web it only shows the events for this week and the beginning of next week (through the beginning of Rosh Hashanah). I've been beating my head against this for a week now, and need some help.
After some testing the past week, we have confirmed this is an issue on Outlook.com. There is no way to force Outlook to refresh a calendar subscription, and for some reason it has stopped refreshing many of the Hebcal calendar feeds.
We have confirmed that if you unsubscribe from a Hebcal calendar in Outlook Web and then re-subscribe, the problem resolves itself immediately and you will see the events in Outlook.com in a matter of seconds. I hope this approach will work for you too!
G'mar Chatima Tova!
Thanks for your message.
We have confirmed that our Jewish Holidays (only major holidays) feed contains only major holidays such as Rosh Hashana, Yom Kippur, Passover, Hanukkah. That feed does NOT include minor & modern holidays, fast days or Rosh Chodesh.
We offer a separate Jewish Holidays (all holidays) feed which contains major, minor, modern Israeli holidays, fast days and more.
You can subscribe any of these specialized feeds at https://www.hebcal.com/ical/
We note that you mention "Gedaliah Fast" and not "Tzom Gedaliah". Some non-Hebcal holiday feed providers (for example Google Calendar itself) use the event title "Gedaliah Fast". If you're seeing that event title and not "Tzom Gedaliah" then it suggests that you didn't subscribe via Hebcal.com. For the fast of Gedaliah, only use the title "Tzom Gedaliah"
Downloading 2025-2026 iCalendar produces 2024-2025 calendar
I created a calendar for 2025-2026 and it shows up just fine on the website, but when I download the iCalendar file (.ics) it seems to be last year's calendar 2024-2025. So I tried downloading the CSV file and viewed it. It looks good, but I can't import it into my Calendar program... only .ics files.
Hi, thanks for using Hebcal.
Candle-lighting and Havdalah times are derived from sunset times, which are approximated from a location (latitude, longitude) and day of year. As of August 2020, Hebcal.com calculates zmanim (halachic times) using an algorithm published by the US National Oceanic and Atmospheric Administration. The NOAA solar calculator is based on equations from Astronomical Algorithms by Jean Meeus.
Since 2013, Hebcal.com has been using lat/long definitions from GeoNames.org, which is available under a Creative Commons license. For the USA, we purchase a commercial ZIP code database from zip-codes.com that provides latitude and longitude for the “center” of each zipcode.

Adding CandleLighting minutes used to RSS reply
Alternatively, perhaps making the default used when 'm=on' an attribute of the location block. So that it can be reported as an explanation of the time.
I am allowing the user to provide an int value (1..59) in which case I send `b=${candleMin}` and if empty - `b=on`. But it would be useful when I display the reply to include for the user what time was used. In Beit Shemesh, for example, there are sub-communities using 40 (because it is in Jerusalem district), 30 (I don't know why) and 20 min (a common Israeli alternative to 18) before sunset. So someone may guess the wrong default.
Adding Hebrew name to an exising entry not coming up on our calenadr
Trying to add the Hebrew name when orignally we entered only the english name on the yarzeit list. We add it on the Yarzeit list but it's nt adding to the calenedar on our phone
After making a modification to an existing Hebcal Yahrzeit + anniversary calendar, it takes 24-48 hours for these changes to show up on your mobile phone. This delay is caused by the calendar app which only checks for updates to the Hebcal personal calendar feed at most once per day.
paid link
I see there's a "paid link" to the JPS B'nai Mitzvah Commentary pamphlets.
Can I talk to someone about setting up a link to my TropeColor website? What's the cost?
I am the Torah and Megillah Tropes Specialist at Rabbi Jack Pressman Academy at Temple Beth Am in Los Angeles, CA, going into my 8th year there, and I've been teaching B'nai Mitzvah for 53 years, using my color-coding system.

Sorry, we aren’t accepting new paid links at this time. We try to keep advertising on Hebcal.com to a minimum to cover our web hosting costs
