Zmanim (halachic times) iCalendar feed

We are pleased to offer an experimental Zmanim (halachic times) iCalendar feed. Many calendar desktop, mobile or web apps support the iCalendar (.ICS file extension) format.

You can specify your location using a GeoNames.org numeric ID, a United States ZIP code, or a geographic position (location specified by latitude, longitude, and timezone). You’ll find details on how to specify the location parameters on the Zmanim (halachic times) API page.

By default, event titles use a Sephardic transliteration. Append &lg=LANG to the URL to render the events titles using an alternate event language.

Option 1: All zmanim in a single daily untimed event

The basic URL format of the feeds is this:

webcal://download.hebcal.com/zmanim2?geonameid=5368361

The calendar feed will contain zmanim for the next 90 days. There will be a single all-day (untimed) event with the Hebrew date, and the description/notes will contain all times. Here is an example event:

Option 2: Timed events

If you would prefer approximately 20 timed events per day, we offer an alternate feed format using this alternate URL format (note /zmanim instead of /zmanim2 above):

webcal://download.hebcal.com/zmanim?zip=02906

The calendar feed will contain events for the next 60 days. Each event represents only a single halachic time.

Here’s an example of the events included in the calendar feed:

Option 3: Sunrise and Sunset only

An alternate feed which contains only sunrise and sunset events is available using URL format like this (note /sunrs instead of /zmanim2 above):

webcal://download.hebcal.com/sunrs?zip=02906

In this variation, there are only two events per day.

Asara B’Tevet in January or December

Asara B’Tevet / עֲשָׂרָה בְּטֵבֵת, the tenth day of the Hebrew month of Tevet, is a minor fast day in Judaism. The fast commemorates the siege of Jerusalem.

Although the Tenth of Tevet is an annual observance on the Hebrew calendar, the date can fall during December or January on the Gregorian calendar. In some Gregorian years, there is no observance of the fast. In other Gregorian years, the fast is observed twice.

For example, the Tenth of Tevet does not occur at all in during the Gregorian year 2024. The fast for Hebrew year 5785 will be observed in January 2025, and the Asara B’Tevet 5786 observance of the fast will be in occur in December 2025.

To illustrate further, consider the following 8-year table:

Triennial Torah Readings

The Hebcal Torah Reading pages specify both the traditional full kriyah (reading the entire weekly Torah portion each Shabbat) and also a triennial cycle specified by the Conservative Movement in the United States.

“Many congregations pattern their weekly Torah reading cycle after a system similar to the one used in ancient Israel during the rabbinic period. In this system, the traditional parashiot are each divided into three shorter segments, and the whole Torah is completed once every three years. The system has both advantages and disadvantages, but its ability to shorten the length of Torah reading without sacrificing the complete reading of the Torah on a regular basis has made it the choice of some synagogues in the Conservative Movement.”

Updates and modifications to Conservative triennial schedule for Diaspora

Update August 2022: for Parashat Vayakhel and Parashat Pekudei, Hebcal uses the modification provided in An Emendation to Richard Eisenberg’s Complete Triennial System for Reading Torah, to Address a Rare Situation, Committee on Jewish Law and Standards of the Rabbinical Assembly, 2012

Update December 2021: Hebcal adopted CJLS’s modifications triennial cycle for some combined parshiyot to change the reading for year 3 to be the third section of the parashah. Modification of the Triennial Cycle Readings for Combined Parashot in Certain Years, Rabbi Miles B. Cohen, 2020

Masorti triennial schedule for Israel

Although there is no formally specified triennial cycle for the Masorti movement in Israel, Hebcal began publishing a draft schedule in May 2023. Due to differences in the Torah readings schedule based on keeping only a single day of chag in Israel, the Diaspora triennial system does not work for a small number of parsha combinations that can occur in Israel.

In particular, Behar-Bechukotai and Matot-Masei occasionally occur with different 3-year patterns in Israel that never occur in the Diaspora. Rather than invent new aliyot divisions for Israel, we have adapted/reused the existing triennial variations used in the Diaspora.

Here is the draft schedule with some example years where the 3-year patterns occur.

Matot-Masei: 3-year pattern “STS” (Separate in 5774, Together in 5775, Separate in 5776)

Daily learning: Tehillim (Psalms)

We have added the monthly cycle of studying Tehillim (Psalms) to our daily learning calendars.

Each day, we study a few chapters from the 150-chapter book of Psalms (Tehillim). The entire book is completed on the final day of each Hebrew month. On months with 29 days, the 30th portion is combined with the 29th portion.

For example, the reading for the 18th of Sivan, 5783 (Wednesday, 7 June 2023) is Psalms 88-89.

You’ll find the calendar feed for Apple, Google, Outlook on the Jewish Holiday downloads page.
