I’ve read biblical fiction which defines a chapter as, for example, “April, 33 AD”, and it made me wonder… In the time of Jesus, were there twelve months, as there are now? I realize they might have had different names (in ancient Hebrew, Aramaic) that may have been similar to what we have now. Is it known? Or one of those things no one knows? Time had to have been measured somehow. In the case that there might not have been the twelve months we have now, then, to say Jesus lived two-thousand-some years ago wouldn’t be accurate by our standards. It might have been a longer, or shorter time ago, if all along, years weren’t measured within twelve months.
The Jews have a different calendar of their own really,
which they still use now for religious purposes. Yes, there are twelve months, but their months don’t match up exactly with ours. For instance, the month of Nisan (aka Abib, the older name), corresponds to our March-April.
Nisan (30 days) - March-April
Iyar (29 days) - April-May
Sivan (30 days) - May-June
Tammuz (29 days) - June-July
Ab (30 days) - July-August
Elul (29 days) - August-September
Tishri (30 days) - September-October
(Mar)ḥeshvan (29/30 days) - October-November
Kislev (30/29 days) - November-December
Tebet (29 days) - December-January
Shebat (30 days) - January-February
Adar (29 days) - February-March
In leap years, an extra month (Adar I, of 30 days’ length) is added after Shebat: the regular Adar is referred to as
Adar Beit or “Adar II.” The modern Hebrew names are derived from
the Babylonian names for months (
Nisan = Nisānu ‘(Month of) the Sanctuary’, etc.); the Jews got it during their exile in Babylon. In the older parts of the Old Testament, you see four months referred to by different, Canaanite names (
Nisan =
Abib ‘Spring’;
Iyar =
Ziv 'Second;
Tishri =
Ethanim ‘Strong’ in the plural;
Ḥeshvan =
Bul).
The Jewish New Year (
Rosh Hashanah) is in Tishri 1-2, Yom Kippur is in Tishri 10, Sukkot (Feast of Booths) is held during Tishri 21, Hanukkah occurs in Kislev 25, Passover is at Nisan 14, Shavuot (Pentecost) is at Sivan 6. But since the Jewish calendar isn’t synchronized with our modern Gregorian calendar, the dates these feasts fall on our calendar changes every year. For example, Jewish New Year fell last year on September 24-26 last year, but this year it would fall on September 13-15.
