30 day months
Hello,
Thanks for the calendar. Have you ever tried making a calendar with 30 day months?
The Beginning 7:11 and 8:3,4. 11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, in the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. 8:3 And the waters returned from above the earth, going and returning: and after the end of the hundred and fiftieth day the waters abated. 4 And in the seventh month, in the seventeenth day of the month, the Ark rested upon the mountains of Ararat.

Encyclopædia Britannica has an excellent introduction to the Jewish calendar. Another well written treatment of the Jewish calendar can be found in Understanding the Jewish Calendar by Rabbi Nathan Bushwick.

How to merge calendars?
I am not very tech savvy but would like to merge the various Yartzeit calendars I've created here, into one usable calendar. Is this possible to do?
Thanks for your help!
Be well...and may we never need to add any more names to our Yartzeit lists!

Why can’t we go back to Creation?
I’ve seen you write in a few places about dates before the 1700s BCE not being accurate because of 10 days added. But the days went from Wednesday to Thursday being the next day.. so if all cultures including our culture still kept a 7 day calendar, shouldn’t we be able to zoom out and go back 5785 years ago and see exactly to this day, what day of the week it was on day one?
We would be using the Jewish year and cycle, and the Wednesday to Thursday change shouldn’t effect anything because it’s still accurate within the days of the week.

merge yearzit+birthdays in the creating calender
Hi
could you please add option to add the calendar created in the yearzit+birthdays in the limud yomi settings. So we could create a calendar with Daf Yomi and events.
thank you.

Thanks for using Hebcal and thank you for this suggestion.
Because the commonly used calendar apps from big companies (Google, Apple, Microsoft) all support the ability to view multiple calendar feeds together, we don’t plan to add this feature to Hebcal.
Calendars created by Hebcal are easily downloaded and imported into various calendar apps, including iPhone, Google Calendar, Outlook PC, Outlook Web, macOS Calendar, and any app that supports iCalendar (.ics) feeds or subscriptions.
