We are aware that WebCal.Guru charges a monthly subscription. It's a very high quality website with tons of customizations and options. You get what you pay for.

We do have experimental iCalendar feeds you can add to Google Calendar for sunrise/sunset only, and for the full set of Zmanim (halachic times). These are free to use, with the caveat that they don't offer any customization. This is an iCalendar feed variation of our Zmanim developer API.

For sunrise/sunset only, you can subscribe to this iCalendar feed (replace zip= with your USA ZIP code, or use geonameid= with a GeoNames.org ID for any of 100,000 world cities supported by Hebcal.com)

For the full experimental Zmanim iCalendar feed, you can use this URL format

Thanks for the suggestion. We'll endeavor to add this in the coming weeks.

Hi, thanks for using Hebcal. We're happy to hear that you were able to add Hebcal events to Google Calendar, and sorry to hear that you're having trouble getting Google Calendar events to sync to your iPhone.

Regarding editing the calendar, you do have several customization options (for example turning on/off Rosh Chodesh, modern holidays, fasts, etc). However, you don't have the ability to edit individual events.

Does this answer your question?

Hi, thanks for using Hebcal.

To download Hebcal to Outlook on Android, first follow these instructions to get Hebcal events on your Outlook.com calendar:

https://www.hebcal.com/home/4400/outlook-web-jewish-holidays

After that, your Outlook.com web calendar will sync automatically with Outlook for Android.

No, you should not need to take any action. If you subscribed to our perpetual feed, the new dates will simply appear when Google refreshes our feeds (which are scheduled to happen approximately weekly).

Thanks for using Hebcal. So sorry for the delay. Our 2-year feeds will be refreshed in another week.

hi, thanks for using Hebcal.

Shavuot occurs 50 days after the start of Passover. Please note the counting of the Omer begins on the 2nd day of Passover, not on the first Shabbat of Passover.

You're welcome. Happy to hear that the instructions worked for you.

If you'd like to add Jewish holidays back to your calendar, you can visit https://www.hebcal.com/ical/

That page offers free Jewish holidays for Microsoft Outlook, iPhone, iPad, macOS Desktop Calendar, Android (via Google Calendar), or to any desktop program that supports iCalendar (.ics) files.

There are many options to choose from. If you only want major holidays, choose the Jewish Holidays (only major holidays) option. That feed includes major holidays such as Rosh Hashana, Yom Kippur, Passover, Hanukkah. It does NOT include minor & modern holidays, fast days or Rosh Chodesh.

You can also create your own custom calendar with different event languages, candle-lighting times and more. If you wish to follow those instructions, you'll find them for Apple Calendar on macOS here:

Looks great! Now please follow the remaining steps 3 and 4 on the "delete Hebcal merged events" instructions.
