Year Parameter Default
What is the default range of data of the API response for the Jewish Calendar API if I don't set the year parameter?
It used to pull for me the current Hebrew Year, and now I see it's pulling this coming Hebrew year (5785)
If you set &yt=H (which it appears you are doing) but you don't want to specify a Hebrew year explicitly, you should consider using &year=now for the current Hebrew year.
If you don't specify year= (or start= and end=), I believe the API will default to the current Hebrew year from 1 Tishrei - 15 Av, and the following Hebrew year starting on the 16th of Av.
Incorrect Rosh Hashanah Day 2 Haftorah Reading Reference
For the Rosh Hashanah Day 2 Haftorah Reading:
The reference is shown as Haftarah: Jeremiah 31:1-19 · 19 p’sukim
This is incorrect. The correct reference is Jeremiah 31:2-20, which I have cross-referenced against Sefaria.org, Etz Hayim, Lev Shalem, and other Machzorim.
The Haftorah starts with Ko amar Adonai matza chein bamidbar
and ends ...racheim arachamenu n'um Adonai.
This corresponds with Jeremiah 31:2-20.
Thank you for all you do!
The Hebrew date converter is not designed to be accurate for year 1752 C.E. and earlier.
Hebcal does not take into account a correction of ten days that was introduced by Pope Gregory XIII known as the Gregorian Reformation.
Holidays blocking my calendar as busy
Various holidays are blocking the entire day as busy, regardless of start/end time--but erev and Shabbos are free. Can you make a way to turn on/off the busy setting so we have more control over our calendar?
Hi, thanks for using Hebcal.
If you're using the default "subscribe" feature for most calendar applications (Apple, Google, or Microsoft Outlook), then your calendar will never be blocked. The Hebcal holidays will be displayed and managed as separate calendar from your main calendar without affecting your main calendar's free/busy time.
If, in fact you imported Hebcal events and merged with your calendar (using our .ics download + import, or the .csv download + import), then yes, holidays that are yom tov such as Rosh Hashana, Yom Kippur, the beginning days of Sukkot, Simchat Torah, the beginning and ending days of Pesach and Shavuot, will indeed be blocked all day (typically using the "out of office" type, but in some cases "busy"). This is a feature, not a bug, because work is forbidden on those major holidays.
We're sorry, but we don't have the ability to offer customizations for these major holidays. If you choose to download/import/merge, then you'll need to adjust any holidays from busy/oof to "free" on your own.
Make/Integromat integration
I know for a fact there is a Make/Integromat integration. can someone please add a link for installation in the comments? Thank you
discrepancy in results
Hi, I've developed a VBA program that converts a Gregorian date into a Hebrew date.
In most cases your results and mine are identical,
however in some cases the results are not identical.
for example, 23/09/2239 (Sep. 23, 2239): My program's Hebrew date is: כ"ט באלול, תתקצ"ט
whereas your solution is: כ"ג באלול, תתקצ"ט
when displaying this date in Excel: Locale (Hebrew) Calendar type (Hebrew Lunar)
the result is identical to mine: יום שני 29 אלול 5999
Can you please explain why?
Google calendar integration
After years of flawless integration, my Google calendar (in daily view) suddenly displays the Hebrew calendar as a separate parallel day instead of integrating it with my main calendar. This started suddenly on 09 September 2024.
Hi, thanks for using Hebcal and the Google Calendar integration. We're sorry to hear that you're having difficulty seeing an integrated view and are now seeing a separate parallel day. Unfortunately, we can't help much here - we haven't made any change on our end that could cause your Google calendar daily view to appear any differently.
Perhaps there is a setting you can change on the Google Calendar side?
How to switch white text on black background to black text on white background?
Hebcal used to be black text on white background. But sometime ago the colors flipped. Now it's white text on black background. It's hard for me to read text on a black background. Is there a way to modify that? I tried to use the HELP button, but it does not work.
