Hi, we're very sorry.
Now defunct: previously there was a macOS Hebcal Dashboard Widget by Mark Saper, but it’s no longer being maintained.
Apple no longer supports Dashboard widgets either.
Rabbi Nathan Bushwick’s Understanding the Jewish Calendar explains some of the mathematical and scientific underpinnings of the calendar.
Hi, thanks for using Hebcal and thanks for your patience!
As you have noticed, calendars exported from Hebcal to Apple or 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).
Subscription feeds are the recommended approach because they are easier to manage (with different alarm options, etc) and because Jewish calendar events can be displayed in a different color.
If you'd like to capture historical holidays from Hebcal and merge them into your personal calendar, this can indeed be done with a little bit of additional export/import effort.
You can visit our https://www.hebcal.com/hebcal page and enter a past year (for example 2015) in the form and then click on the Create Calendar button.
On the calendar results page, click the Download button and note the "Alternate option" text at the very bottom of the Download dialog box.
Alternate option: Download hebcal_2015.ics and then import manually into Apple macOS Calendar.app.
If you click on this link, it will download a file (not a subscription feed) with exactly one year of events, which you can then import into your preferred calendar application.
You can find past dates for Passover here

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!
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

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.
Yes!
