This API uses a similar URL and response format as our full Jewish calendar REST API, but offers less control over the dates and times. If you find you want more fine-grained control over the date ranges, or what kinds of events are included and which are excluded, we recommend using the full Jewish calendar REST API instead.
Thirteen times between 1800-2200.

Thanks for getting back to me. We need to first do the lower-level Zmanim integration. We have to do a small amount of porting from KosherZmanim/KosherJava because that 4-year-old package depends on the bloated Luxon library; our fork uses the new JS Temporal.
Once that's done, it should be more straightforward to add a "Chabad" checkbox to the Hebcal Custom Calendar creator, and a Chabad option for the iCalendar feed for Zmanim.
Again, no promises on when - this is probably a day or two of work. We'll keep this ticket open and update as we make progress and have something for you to test.
Thanks for this suggestion. We will endeavor to add these to the Hebcal TypeScript libraries. We can't promise a date by when we will complete these - Hebcal is a volunteer gig, not our day job.
Would you expect to use these as a software developer via web APIs like our Zmanim (halachic times) API, or as an end user with some sort of web pages and calendar feeds?
Note that we don't currently have any Zmanim web pages on hebcal.com, and our iCalendar feed for Zmanim is considered experimental and doesn't really have a proper web UI. The hebcal.com website is currently more focused on holidays, date conversion, Yahrzeits, and Torah readings. It only exposes a very limited subset of zmanim (candle-lighting, havdalah, and fast start/end times) to end users via the custom calendar creator feature.
We have added this feed to to https://www.hebcal.com/ical/

Encyclopædia Britannica has an excellent introduction to the Jewish calendar. Another well written treatment of the Jewish calendar can be found in Understanding the Jewish Calendar by Rabbi Nathan Bushwick.
