On my iMac calendar I had 58 copies of Hebcal, deleted them one by one. Now I have 70 copies of Hebcal in my calendar and my calendar is frozen. On the phone with Apple for 2 hours. Nothing worked.

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

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:

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

בממהיר תאריכים לתאריך כ תמוז תשפ"ב כתוב פרשת פנחס 

למרות שבפועל זה פרשת מטות

I'm putting together a page that will show the Parsha hashavua and specific times for a given Hebrew year. 

The hebcal.com/hebcal? API will give me the Shabbat dates for a year, but only (as far as I can see) a Gregorian year. 

I tested out the &start= and &end= option which is documented in the hebcal.com/zmanim page, and found it works. 

The fact that it works is lovely. The fact that it's not described on the hebal.com/hebcal page is perhaps less lovely. I'm willing to pitch in and help with the documentation if that helps.

Aliyah #4 for Rosh Hodesh + Chanukah on a weekday (e.g. Day 7 in 2021) is listed as a maftir, but there is no Haftarah that day. It should just be the 4th aliyah.

Trying to add calendar for 2022 onwards to Google, when it switches to the calendar app, says that calendar no longer exists
