Dedicated Rosh Chodesh calendar
It would be very useful to have a calendar that could be subscribed to that solely marks which days are Rosh Chodesh.

Chofetz Chaim Daily
Would you be able to add the option for the Chofetz Chaim Daily calendar as well as the Shmiras Haloshon Daily calendar? They are both very popular seforim from Reb Yisroel Meir Kagen. They can be added as a feature similar to Daf Yomi.

This year (2023) Hebcal shows that April 19 is the 28th of Nisan. Does that mean that the 28th of Nisan starts at sundown on April 19 or that the 28th of Nisan started at sundown on the 18th of April? And why isn't this fundamental issue clearly address
This year (2023) Hebcal on my iPhone Calendar app and on my Mac laptop Calendar app shows that April 19 is the 28th of Nisan.
Does that mean that the 28th of Nisan starts at sundown on April 19 or
Does that mean that the 28th of Nisan started at sundown on the 18th of April?
And why isn't this fundamental issue with the Hebrew calendar clearly addressed all over the Hebcal website?

I had this on my Apple Watch and then I got a new watch. But it won’t allow me to redownload the app on my new watch. And in App Store it doesn’t give me the option to download. Can you please help?

We've posted a slightly longer set of instructions here:

Hi, thanks for contacting Hebcal. You can create a personal list of Yahrzeit (memorial) and Yizkor dates, Hebrew Birthdays and Anniversaries for 20+ years at this page:
https://www.hebcal.com/yahrzeit
If you know the Hebrew but not the Gregorian date, you can use the Hebrew Date Converter to get the Gregorian date of death, and then come back to the Yahrzeit + Anniversary calendar page.
If you don't know the Hebrew year, it may be difficult to get a correct date conversion. You could try to estimate it, but you might end up with an incorrect result. The rules for calculating birthdays and yahrzeits are a bit complicated and depend on the actual attributes of the Hebrew year they occurred in -- was it a leap year (Adar vs. Adar I vs. Adar II)? Short Kislev? Long Cheshvan? For more details, you can read the article How does Hebcal determine anniversaries (birthdays, yahrzeits) in Adar, Cheshvan, or Kislev?

REST API multiple geonameid
Hi
I am building a wordpress plugin to show Shabbat times for user defined geonameid.
Is there a way so send multiple geonameid to the REST API so that is returns multiple locations?

Thanks for using Hebcal APIs.
Our REST APIs accept only a single geonameid. There is no way to send more than one in a single request. The only way to get events for multiple locations is to make multiple API requests.
Golf luck with your application!

Hi, thanks for using Hebcal.
If you used the Hebcal Android (Google Calendar) download instructions, then you should be able to view the same holidays on Google Calendar on your laptop.
Please note, there is a confusingly similar named Android app called HebCal & Widget available on the Google Play store. This app is not affiliated with Hebcal.com in any way. It is developed by a completely separate organization called BotenSoft. The Hebcal name isn't trademarked so we can't stop them from using it.
Although they use the same name, we have no relationship with BotenSoft and cannot offer support for their app.
