Hebrew Date Converter REST API not showing Omer

Mike Feingold 3 years ago updated by Michael J. Radwin 3 years ago 3

I'm using the Converter REST API.

According to the documentation (here, near the bottom of the page) this should return the day of the Omer.

However when I try it (https://www.hebcal.com/converter?cfg=json&gy=2021&gm=4&gd=5&g2h=1) then no Omer event is returned in the Events section.

Am I missing something?

Yahrzeit dates from Jewish calendar REST API

tZkSs 3 years ago updated by Michael J. Radwin 3 years ago 2

Is there a way to get Yahrzeit dates from Jewish calendar REST API

I need to get next anniversary dates by looking at date of death a person. 

I tried to find the solution on Hebcal site, they are provided a REST API for calendar, and UI to calculate that dates also, but I could not to find REST api method for it

this is the UI,https://www.hebcal.com/yahrzeit

I need that data as JSON from REST API.


If anyone have experience on that please let know me


Thanks

We've released some experimental support for an API here.

Documentation is forthcoming, but the basic idea is that you'll need to POST x-www-form-urlencoded data to https://www.hebcal.com/yahrzeit with the special parameter cfg=json

For example:

curl 'https://www.hebcal.com/yahrzeit' \
-H 'content-type: application/x-www-form-urlencoded' \
--data-raw 'cfg=json&n1=Example1&t1=Birthday&d1=15&m1=4&y1=1983&s1=on&n2=Example2&t2=Yahrzeit&d2=13&m2=11&y2=2008&s2=off&hebdate=on&years=20&v=yahrzeit' \
--compressed

Shabbat Hanukkah maftir - only one prince

Josh Greenfield 3 years ago updated by Peggy Knox 2 years ago 3

The Hanukkah Torah reading for weekdays (per Ashkenazic custom outside of Israel) is two days of the princes bringing offerings from the section of Numbers 7 (e.g., on day 3 of Hanukkah we read of the prince who brought offerings on day 3), plus the prince who brought offerings on day 4).  On Shabbat of Hanukkah (when not also Rosh Hodesh) we read the regular Torah reading for 7 aliyot, and the maftir reading is just one prince, corresponding to that day of Hanukkah (e.g., if Shabbat is day 3 we read of the prince from day 3 only).  Hebcal.com right now is showing that the Shabbat of Hanukkah this year we read from Numbers 7:18-29, which is two princes:

https://www.hebcal.com/sedrot/vayeshev-20201212

I'm guessing the algorithm is just using the weekday Hanukkah custom to figure out what the Shabbat maftir reading should be, but that seems to be incorrect.  For the source of the Hanukkah reading, you can check Shulkhan Aruch OH 684:2 (note 6 in the Mishnah Berurah specifies only one prince in the maftir).

Yom Kippur Katan

nsuffin 4 years ago updated by Michael J. Radwin 3 years ago 2

With all of the different dates currently included in Hebcal, would it be possible to please also add Yom Kippur Katan?

Answer
Michael J. Radwin 3 years ago

Update: we've added a Yom Kippur Katan calendar feed to the Hebcal website. You can find it towards the bottom of the Jewish holiday downloads page.


Yom Kippur Katan

יוֹם כִּפּוּר קָטָן is a minor day of atonement occurring monthly on the day preceeding each Rosh Chodesh.
9 calendar events per year. 10-year perpetual feed.


Yom Kippur Katan is omitted in Elul (on the day before Rosh Hashanah), Tishrei (Yom Kippur has just passed), Kislev (due to Chanukah) or Nisan (fasting not permitted during Nisan). When Rosh Chodesh occurs on Shabbat or Sunday, Yom Kippur Katan is observed on the preceding Thursday. [1]

Complete set of candle lighting times for a chag

Rachel 4 years ago updated by Michael J. Radwin 3 years ago 1

I would greatly appreciate your sending a complete set of candle lighting and Havdalah times for a chag BEFORE the chag begins. 


I looked up the times for the last 2 days of Pesach at another site during chol hamoed, so I could post them on my kitchen cabinet IN ADVANCE. 

I was sent the times via HebCal AFTER the 7th day had already started (east coast USA) which was not helpful. 


This type of issue has happened before, and is very frustrating and disappointing. I appreciate the HebCal email service, but it’s disturbing that the info is incomplete. It also leads me to wonder if the info is reliable, since this type of problem is easily preventable by better planning.

Hi, thanks for using Hebcal. We're sorry to hear that our weekly email updates didn't arrive in a timely fashion last year. We've made some changes recently to ensure that doesn't happen again.

We'd also like to encourage you to take a look at our Candle-lighting Times Year at a Glance tool. You can fill out a form to get Shabbat and holiday candle lighting times and Parashat haShavuah (weekly Torah Portion) for the entire year on a single page. You can print it out and post it on your refrigerator.

Shana Tova!

Hi, thanks for using Hebcal!

Follow these instructions to add a Hebcal Jewish holiday calendar 5-year feed to Outlook.com (also called outlook.live.com Calendar). This technique will also work with Windows 10 devices (desktops, laptops, tablets and phones) that have a built-in calendar application that connects to Outlook.com or MSN.

Alexa, what time is Shabbat in Israel

Chaykee 4 years ago updated by Michael J. Radwin 4 years ago 4

I really love that I can ask Alexa what time shabbos is but if your data set is based on zip codes only, I get times for California instead of ISRAEL! Please please update this skill to accommodate international use!!

No events generated for iOS since the end of 2019! I tried removing the calendar subscription and re-adding it multiple times. Ideas?

There are no events generated for iOS since the end of 2019! I tried removing the calendar subscription and re-adding it multiple times. Ideas?

Answer
Michael J. Radwin 3 years ago

Hi, thanks for using Hebcal

Calendars exported from Hebcal to Google Calendar or other services that support iCalendar subscription feeds are typically “perpetual”. That is, they contain events for the current year (Gregorian or Hebrew) plus some number of years into the future. Our calendars typically have 5 years of events (current year plus 4 years into the future).

Size limitations imposed by Google and other calendar clients require that we limit the number of events per feed. The total number of years is now reduced to 4 years if you check some options that include many events (“Candle lighting times”, “Days of the Omer” or “Show Hebrew date for dates with some event”) or 2 years if you check options that include one event every day of the year (“Daf Yomi” or “Show Hebrew date every day of the year”).

Note that if you’d like to include the Hebrew date for every day of the year, you can subscribe to that calendar via a separate calendar feed at our Jewish Holiday downloads page. Look for Hebrew calendar dates (English) or Hebrew calendar dates (Hebrew).

An added advantage of this approach is that you can choose separate colors in Google Calendar or iOS/iCloud calendar for the daily calendar event feed.
