Hi, thanks for using Hebcal

Calendars exported from Hebcal to Google Calendar or other services that support iCalendar subscription feeds are typically “perpetual”. That is, they contain events for the current year (Gregorian or Hebrew) plus some number of years into the future. Our calendars typically have 5 years of events (current year plus 4 years into the future).

Size limitations imposed by Google and other calendar clients require that we limit the number of events per feed. The total number of years is now reduced to 4 years if you check some options that include many events (“Candle lighting times”, “Days of the Omer” or “Show Hebrew date for dates with some event”) or 2 years if you check options that include one event every day of the year (“Daf Yomi” or “Show Hebrew date every day of the year”).

Note that if you’d like to include the Hebrew date for every day of the year, you can subscribe to that calendar via a separate calendar feed at our Jewish Holiday downloads page. Look for Hebrew calendar dates (English) or Hebrew calendar dates (Hebrew).

An added advantage of this approach is that you can choose separate colors in Google Calendar or iOS/iCloud calendar for the daily calendar event feed.

Here's an article that explains the number of years in the feed in more detail

Hi, thanks for using Hebcal!

If you subscribe to one of the Hebcal simple calendar feeds as your screenshot above shows, those are generic for the Diaspora and don't include any city-specific candle-lighting times.

To get candle-lighting times for macOS Calendar.app and include candle-lighting times for your city, follow these instructions

https://www.hebcal.com/home/632/how-to-make-changes-to-a-yahrzeit-anniversary-calendar

This article describes how to make changes to a Yahrzeit + Anniversary calendar that you downloaded, exported or subscribed to in a calendar app like Outlook, Google Calendar / Android, or Apple (iOS, iPhone, iPad or Mac).

If you used Hebcal to create your personal calendar after August 2020 and you subscribed using the recommended feed option, you can click on the hebcal.com URL at the bottom of a calendar event. That link will take you back to the Yahrzeit and Anniversary calendar where you can make edits to each person’s name or dates.

If you subscribed before August 2020, you will need to delete or unsubscribe the calendar containing your yahrzeit and anniversary reminders. Hebcal personal event calendars created before this date do not support editing event dates or names. Directions for how to delete/remove a subscribed calendar vary by calendar application.

You may have downloaded yahrzeit/anniversary events and merged them into your regular personal calendar (often called “Home” or “Calendar”). To remove those events, search for the event(s) in your regular calendar and remove/delete them one at a time. These events will always have one of the following titles: “Yahrzeit”, “Hebrew Birthday” or “Hebrew Anniversary”.

Once you have removed the yahrzeit/anniversary calendar events, return to Hebcal.com and re-enter in all of the event details, then download again.

Hi Saul, thanks for being a long time Hebcal user and reporting this bug many years ago. 

We were finally able to reproduce this error on Outlook 365 web. We made two changes to our iCalendar feeds to fix the problem for you:

1. Our .ics feeds so they include X-MICROSOFT-CDO-ALLDAYEVENT:TRUE which according to some Microsoft documentation might fix the problem.

2. Our VTIMEZONE implementation for Asia/Jerusalem (the timezone that is used throughout Israel) has been modified so it only uses a simpler, current Daylight Saving Time rules (which clocks are advanced by one hour, beginning on the Friday before the last Sunday of March, and ending on the last Sunday of October). This is perfectly accurate for any calendars 2013 and later (when the Israeli government standardized and simplified DST rules).

Shana Tova!

When the 9th of Av falls on Shabbat and the Tish’a B’Av fast is postponed to the 10th, the calendar event now says “Tish’a B’Av (observed)”.
