Hi, thanks for using Hebcal!
If you uncheck some options such as Rosh Chodesh, there will indeed be Gregorian months where no Jewish holidays occur.

Shabbat times are different then chabad.org times
I noticed that the shabbat times are a bit different the those times on chabad.org
why is that? and is there a way to input which minhag you want the times to display via the REST API?

Asara b'Tevet fast start times are incorrect (in some cases showing up as after the end of the fast)
When I download or subscribe to the calendar for 2020, I see on January 7th, the fast ends at 5:20 pm (NY time) and the fast starts at 5:52 pm. Similarly, for December 25th, I see Fast begins at 5:50 pm and no fast starting time. I see this whether I subscribe to an iPhone calendar, or via Google Calendar, or by downloading .ics (you can see this: SUMMARY:Fast begins
DTSTART;TZID=America/New_York:20201225T175000). The .csv download seems to be correct, however.

Bug: export to *.ics - Fast begins bad time.
When I export my calendar to a *.ics file all "Fast begins" contain the wrong time. For example 17:11 instead of 5:11

Hanukkah candle lighting dates are different when using converter
Hi, I tried to convert the first day of candle lighting on Hebcal converter. When entering 10 December 2020 ( After Sunset), it says Chanukah: 2 candles. The Hebcal calendar says Chanukah starts 10 December 2020 at sundown which means we light 1 Candle with shamash? It would be very helpful if someone can confirm this. Thank you.

Thanks for the feedback. We agree that the date converter gives confusing results. We have changed it for past and future years to be more clear:

When you look at the month view on the calendar results page or via one of our downloads, we still display the number of candles
December 2020
Sun | Mon | Tue | Wed | Thu | Fri | Sat |
---|---|---|---|---|---|---|
1 | 2 | 3 | 4 | 5 | ||
6 | 7 | 8 | 9 | 10 Chanukah: 1 Candle | 11 Chanukah: 2 Candles | 12 Chanukah: 3 Candles |
13 Chanukah: 4 Candles | 14 Chanukah: 5 Candles | 15 Chanukah: 6 Candles | 16 Chanukah: 7 Candles | 17 Chanukah: 8 Candles | 18 Chanukah: 8th Day | 19 |

Chanukah API schema changed?
Hi, I have a website (maoztzur.com) that displays the time for candle lighting for Chanukah.
I use this API request to get the number of candles and the time for candle lighting for a given location: https://www.hebcal.com/hebcal/?v=1&cfg=json&maj=on&min=off&mod=off&nx=off&year=now&month=x&ss=off&mf=off&c=on&geo=pos&m=0&s=off&latitude=51.6093316&longitude=-0.2951551&tzid=Europe/London
However it looks like this is now broken because of an API schema change.
It used to be that the time of candle lighting was included in the `title` field of each item in `items[]` in this format: "Chanukah: 8 Candle: 6:18pm". I had a regex to parse this: ^Chanukah: (\d) Candles?: (\d\d?:\d\dpm)$
However it seems that the format has changed. Now the `title` field only says "Chanukah: 8 Candles". However I can see there is a new `date` field on each `item` in the format of "2020-12-17T16:51:00-00:00".
Can I confirm that this `date` is indeed the candle lighting time for the specified timezone?
Thanks

Yes, confirmed. If the `date` field contains a `T` then it includes a time in the timezone specified by the candle-lighting setting.

Hanukkah Candle times are showing an hour too late except on Friday evenings, Eastern Standard Time
Please advise why Hanukkah Candle times are showing an hour too late except on Friday evenings, for Eastern Standard Time.

Hi, thanks for using Hebcal!
According to our sources, Chanukah candles should generally be lit at nightfall, except for erev Shabbat when they must be lit at regular candles lighting time (18 minutes before sunset).
