Calendar use

Hi, thanks for using the Hebcal Yahrzeit + Anniversary Calendar.

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 depending on the month of the death, 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, read the article How does Hebcal determine anniversaries (birthdays, yahrzeits) in Adar, Cheshvan, or Kislev?
