Hi Steven, thanks for catching this bug. The logic for picking today's date when there is no start, end or date parameter was defaulting to today's date in UTC instead of the date at the timezone based on the location.

The issue has been fixed now and those different URLs should give consistent results.

You can always specify an explicit date like https://www.hebcal.com/zmanim?cfg=json&zip=60613&date=2021-03-12 if you don't want the implicit "today" feature.

Hi, thanks for using Hebcal.

Yahrzeit refers to the anniversary, according to the Hebrew calendar, of the day of death of a loved one. Alternative spellings include yahrtzeit, yortsayt, and yartzeit. On the anniversary of a death, it is the custom to light a candle to commemorate the departure of a loved one. ^[1]

In the form, enter the date of death (or birth or anniversary). Use the "+ Add another name" button at the bottom of the page to add additional names. After you generate a personal anniversary calendar, you will be able to print, subscribe to annual email reminders, or download a multi-year calendar feed to Apple, Google, Outlook, or other web, desktop and mobile calendar apps.

Hi, thanks for the generous offer! We'd love your help to offer a Portuguese transliteration.

You can use a tool like Poedit to create the translation file https://poedit.net/

We suggest you download a file like the Spanish language translation, and rename it "pt.po" and then make your edits there. Once you've finished, you can email the file to webmaster@hebcal.com and we will incorporate it into the website within a few days.

Hi, thanks for using Hebcal.

Can you check your candle lighting times and confirm you are using 18 minutes before sundown? This is the Hebcal default but you may have set it to another value, for example 38 minutes before sundown.

Thanks for the bug report! The problem has been fixed now. We're very sorry for the inconvenience.

Hi, thanks for using Hebcal.

You should be able to do this using our Jewish Calendar API by setting the start and end parameters to be today's date in YYYY-MM-DD format, and setting maj=on for only major holidays. Then, you'll need to see if items is empty - and if it's not, check to see if the object inside contains yomtov: true.

For example, here's the second day of Pesach in the Diaspora:

http://hebcal.com/hebcal?cfg=json&v=1&maj=on&leyning=off&start=2021-03-29&end=2021-03-29

{
  "title": "Hebcal Diaspora March 2021",
  "date": "2021-02-08T00:07:43.224Z",
  "location": {
    "geo": "none"
  },
  "items": [
    {
      "title": "Pesach II",
      "date": "2021-03-29",
      "category": "holiday",
      "subcat": "major",
      "yomtov": true,
      "hebrew": "פסח יום ב׳",
      "link": "https://www.hebcal.com/holidays/pesach-2021?utm_source=js&utm_medium=api",
      "memo": "Passover, the Feast of Unleavened Bread. Also called Chag HaMatzot (the Festival of Matzah), it commemorates the Exodus and freedom of the Israelites from ancient Egypt"
    }
  ]

And here's an example of non-yomtov - Chol haMoed Sukkot

http://hebcal.com/hebcal?cfg=json&v=1&maj=on&leyning=off&start=2021-09-24&end=2021-09-24

{
  "title": "Hebcal Diaspora September 2021",
  "date": "2021-02-08T00:11:48.425Z",
  "location": {
    "geo": "none"
  },
  "items": [
    {
      "title": "Sukkot IV (CH''M)",
      "date": "2021-09-24",
      "category": "holiday",
      "subcat": "major",
      "hebrew": "סוכות יום ד׳ (חול המועד)",
      "link": "https://www.hebcal.com/holidays/sukkot-2021?utm_source=js&utm_medium=api",
      "memo": "Feast of Booths"
    }
  ]
}

If you pick a day that has no major holidays, you'll get an empty items array:

http://hebcal.com/hebcal?cfg=json&v=1&maj=on&leyning=off&start=2021-06-01&end=2021-06-01

{
  "title": "Hebcal Diaspora 2021",
  "date": "2021-02-08T00:13:45.611Z",
  "location": {
    "geo": "none"
  },
  "items": []
}

Hi, thanks for using Hebcal, and sorry to hear you're having trouble with your yahrzeit calendar on iPhone.

Could you send us the Yahrzeit calendar subscription URL for debugging via private message? We'd love to investigate further on our server-side to see what's causing the problem.

To remove the Yahrzeit calendar completely, you can follow these instructions:

Hebcal is correct.

When the actual date of Yom Hashoah falls on a Friday, the state of Israel observes Yom Hashoah on the preceding Thursday. When it falls on a Sunday, Yom Hashoah is observed on the following Monday. In the United States, Days of Remembrance runs from the Sunday before Yom Hashoah through the following Sunday.

2021 Thursday, April 8
