Hi, thanks for using Hebcal API. We're sorry to hear that you are having difficulty getting API results for Stuttgart and Strasbourg.

You can use URLs like these to get Shabbat times for these cities.

Please note that the preferred way to access world cities is to use the GeoNames IDs as we've done above.


The following options are available for our APIs:

  • geo=geoname – location specified by GeoNames.org numeric ID
    • requires additional parameter geonameid=3448439
    • Hebcal.com supports approximately 47,000 different GeoNames IDs. These are cities with a population of 5000+. See cities5000.zip from https://download.geonames.org/export/dump/.
  • geo=zip – location specified by United States ZIP code
    • requires additional parameter zip=90210
  • geo=city – location specified by one of the Hebcal.com legacy city identifiers
    • requires additional parameter city=GB-London
  • geo=pos – location specified by latitude, longitude, and timezone. Requires additional 3 parameters:
    • latitude=[-90.0 to 90.0] – latitude in decimal format (e.g. 31.76904 or -23.5475)
    • longitude=[-180.0 to 180.0] – longitude decimal format (e.g. 35.21633 or -46.63611)
    • tzid=TimezoneIdentifier. See List of tz database time zones. Be sure to use the “TZ database name” such as America/New_York or Europe/Paris, not a UTC offset

Thanks for using Hebcal, and thanks for this feedback!

We agree with you and would like to publish more comprehensive Sephardi Haftarot on the website. The regular weekly Torah reading already includes Sephardic Haftarah when it differs from Askhenazi practice, but we do not have the same sources for holidays yet. We do need an accurate and comprehensive source of information for that. Can you recommend a source we could use?

Hi, thanks for using Hebcal.

We believe the date conversions provided by Hebcal are correct. 

The 27th of Adar II, 5736 was in fact Monday, 29 March 1976.

Tuesday, 30 March 1976 corresponds to the 28th of Adar II, 5736.

Gregorian leap years are already correctly accounted for in date conversions. For example, note the date conversions for February 28 and February 29 in 1976:

https://www.hebcal.com/converter?gd=28&gm=2&gy=1976&g2h=1

https://www.hebcal.com/converter?gd=29&gm=2&gy=1976&g2h=1

If you can find another date conversion source that disagrees with our calculations, please post the reference here so we can investigate further.

Hi, thanks for using Hebcal, and thanks for the bug report!

We've fixed the font size issue; please refresh and it should solve the problem.

We have also fixed the links on Israel Torah reading pages to point to the Diaspora versions for Triennial more reliably.

Hi, thanks for writing to us.

In addition to previous output there are now two new outputs

Sunrise plus 3 halachic hours, according to Magen Avraham

sofZmanTfillaMGA – Latest Shacharit (MGA)

Sunrise plus 4 halachic hours, according to Magen Avraham

Hi, thanks for using the Hebcal Yahrzeit + Anniversary calendar.

If you know the Hebrew but not the Gregorian date, use the Hebrew Date Converter to get the Gregorian date and then come back to the Hebcal Yahrzeit + Anniversary calendar page.

Thanks so much for the suggestion! We'll consider these additions for Pesach and Sukkot.

Note that Purim already includes the 🎭️📜 emoji

Sat, 26 March 2022 after sunset is in fact the next Hebrew day, e.g. no longer Shabbat, so in fact it is correctly Parashat Tazria. 

Sat, 26 March 2022 before sunset is Shabbat, Parashat Shmini.

Please examine the "after sunset" box when using the date converter and remember to check the box only when you wish to convert a date after sunset.
