Hello again, we've been alerted to a recent revision to the Triennial aliyot which explains the discrepancy you see between what Hebcal had published and Rabbi Miles B. Cohen's luach.

In November 2020, the CJLS modified the 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

We have implemented the revised aliyah scheme according to the CJLS and updated our web page earlier today to match

https://www.hebcal.com/sedrot/achrei-mot-20220430

Triennial year 3

1: 17:1-7 · 7 p’sukim

2: 17:8-12 · 5 p’sukim

3: 17:13-16 · 4 p’sukim

4: 18:1-5 · 5 p’sukim

5: 18:6-21 · 16 p’sukim

6: 18:22-25 · 4 p’sukim 

7: 18:26-30 · 5 p’sukim 

maf: 18:26-30 · 5 p’sukim


Shabbat Shalom!

Shabbos yom tov and fast day times not hebcal

Hi, we're sorry to hear you are having trouble finding Shabbat yom tov and fast day times on Hebcal.

If you enter your location on our Custom Calendar page you will get candle-lighting times for Shabbat and holidays, and also fast start/end times.

If you're having trouble seeing these times, can you send a URL and/or a screenshot so we can assist in debugging further?

Limits to data returned by start= and end= in zmanim api?

Leon Adato 4 years ago updated by Michael J. Radwin 4 years ago 3

I'm using the https://www.hebcal.com/zmanim and playing with start= and end=. The following URL only returns data up to 10/16/2021 even though I've specified a full year.
https://www.hebcal.com/zmanim?cfg=json&geonameid=3448439&start=2021-09-01&end=2022-08-31

Is there a parameter I'm missing, or a limit on the API, or a difference between running it interactively in a browser versus through a script?

Thanks in advance!

- Leon

Hi, thanks for using Hebcal's Zmanim API!

To avoid excessive CPU usage and ensure quick response times, we limit the total range for Zmanim to be 45 days. If the "end" parameter is more than 45 days after the "start" parameter, is reset to 45 days.

Using the Rest API, an I query the Hebrew day of the month in Hebrew?

mordecai 4 years ago updated by Michael J. Radwin 4 years ago 2

For example, if the Hebrew date is  15 Iyyar 5780, How can I pull only ט"ו

Answer

Similarly, if you want to represent numbers using gematriya, you can avoid using the REST API completely and instead use a simple gematriya function in the programming language of your choice.


Here's the implementation that Hebcal uses. If you don't use JavaScript, you'll see it's extremely straightforward to port to another programming language.

https://github.com/hebcal/hebcal-es6/blob/main/src/gematriya.js

For example, here's a port to Swift

If anybody has this issue, I would appreciate hearing about a solutions.

Logic to iterate through output and grab the "correct" Shabbat

Leon Adato 4 years ago updated by Michael J. Radwin 4 years ago 2

NOTE: The issue below is a programming question. I'm relatively new to "real" coding (versus utility scripts with very narrow scopes), so my belief is that this is a simple case of how to build the correct looping and logic structures. It's not an issue with the API itself or my use of it. I think.
************************
I'm building an automatically-generated list of Shabbat dates and calculating times for mincha, candles, etc based on my shul's particular shitot. I want to grab every Saturday, but I only want to grab each Saturday ONCE.


My problem is that if I set the Major holiday switch (maj) to off, I'm missing some Shabbats.

(example, 9/23 because that's shabbat chol hamoed Sukkot, not a normal Shabbat.)


BUT if I include maj=on, I get some double saturdays

(example: 12/04, which is a 'regular' Shabbat but also noted as the 7th night of Chanukah)


So I need to figure out how to programatically grab or filter the "correct" one.

Here's a sample of the API string I'm generating:

https://www.hebcal.com/hebcal?v=1&cfg=json&maj=on&min=off&nx=off&mf=off&ss=off&s=on&c=off&i=off&leyning=off&geo=pos&latitude=41.4902062&longitude=-81.517477&tzid=America/New_York&start=2021-09-07&end=2022-09-26


To see the current state of the code, check here:
https://clevelandsephardiminyan.com/wp-content/zmanim/fullyear_0-3.php

And the code (such as it is) can be found here:

באג בפרשת שבוע פינחס

If you're using the REST API you can append &i=on to the URL and you'll get results for Israel instead of the Diaspora.

Chanukah candle count seems to be wrong. Tonight, kislev 26, we light 2 candles, not 3

sabrina 4 years ago updated by Michael J. Radwin 4 years ago 1
Answer
Michael J. Radwin 4 years ago

Hi, thanks so much for the feedback and bug report. We investigated the issue and agree that the count looked incorrect for some locations if you visited the Hebcal.com homepage after sunset.

We have modified the candle count to match the correct number of candles based on your latitude/longitude, and we've further clarified by adding the day of the week instead of "tonight"

Chanukah Sameach!
