The Jewish Leap Year

The Jewish Leap Year


The Jewish "leap year", which occurs seven times in a 19-year cycle, has 13 months instead of the regular year's 12. This is so that the lunar-based Jewish year should remain aligned with the solar seasons (12 lunar months make up a total of 354 days -- slightly more than 11 days short of the 365.25 day solar cycle). The added month is called "Adar I" and is inserted before the month of Adar (termed "Adar II" in leap years).

Re: jewish birthday
It's always good to feel young, regardless of how many years actually passed since your birth.

If you were born in a leap year, then in a non-leap year your Jewish birthday is celebrated in regular Adar.

jewish birthday
if born on a leap year, feb 6th 1957-(apparently my birthday would be 5th adar 1 5717.) how many leap years since my birth date? How 'old' would i be?
my kids and I laugh that I'd be 19 but how old would I actually be?

Nobody has been able to help me, so I'd really appreciate it.

Leap Year: when is the "leap month" reduced
How do you calculate the reducing of the "leap month" when it goes above 18/19? Does it fall in February or March of the Gregorian calendar?

Re: Adar 25
I think that in general, unless otherwise specified it is assumed that it occurred in a regular non-leap year or in the second Adar.

Adar 25
I am researching some historical facts about Babylonian king of Nebuchadnezzar. I read an article that he died on Adar 25. I am not familiar on the Jewish calendar. This year there are two Adar months. So in which Adar month, I or II, do I have to consider for the date of the death of the Nebuchadnezzar? March 5(25 Adar I) or April 4 (25 Adar II)?
Thank you for your reply beforehand.

There are many different interpretations given for this idea, and it is used as a reference for various different ideas. One of the simplest interpretations is that each of the six days of creation correspond to one millennium; the first day to the first millennium the second to the second etc.Being that we are currently in the sixth millennium, our times correspond to the sixth day of creation. The closer we get to the end of the millennium, the closer we approach the day of Shabbat, which will result in eternal rest with the era of Moshiach.

Re Shemitah
No, it was not a shemitah year. We are currently in a shemitah year now. The last one prior to that was 2008-5768 Staff

5771 a leap year?
was 5771 a leap year?
Since Biblical times the months and years of the Jewish calendar have been established by the cycles of the moon and the sun. Torah law prescribes that the months follow closely the course of the moon, from its birth each month to the next New Moon.
