Today is Rosh Hashanah, the Jewish New Year, and the first of the High Holy Days. To be more precise, Rosh Hashanah actually began yesterday evening, since the Jews traditionally begin a new day at sunset. This holiday takes place on the first two days of the month of Tishrei in the Hebrew calendar. Because the Hebrew calendar is a lunar calendar, the dates wander a bit in our Gregorian calendar. This year it takes place on September 25-27. The New Year is celebrated for two days because of the difficulty of determining the precise day of the new moon.
Rosh Hashanah, which means “the head of the year”, is not mentioned as such in the Bible. Instead, the day is called “Zikaron Teru’ah” a memorial of the blowing of horns in Leviticus 23:24, and “Yom Teru’ah” the day of blowing the horn in Numbers 23:9.
23 The LORD spoke to Moses: 24 “Tell the Israelites, ‘In the seventh month, on the first day of the month, you must have a complete rest, a memorial announced by loud horn blasts, a holy assembly. 25 You must not do any regular work, but you must present a gift to the LORD.’” (Lev. 23:23-25)
1 “‘On the first day of the seventh month, you are to hold a holy assembly. You must not do your ordinary work, for it is a day of blowing trumpets for you. 2 You must offer a burnt offering as a sweet aroma to the LORD: one young bull, one ram, and seven lambs one year old without blemish. 3 “‘Their grain offering is to be of finely ground flour mixed with olive oil, three-tenths of an ephah for the bull, two-tenths of an ephah for the ram, 4 and one-tenth for each of the seven lambs,note 5 with one male goat for a purification offering to make an atonement for you; 6 this is in addition to the monthly burnt offering and its grain offering, and the daily burnt offering with its grain offering and their drink offerings as prescribed, as a sweet aroma, a sacrifice made by fire to the LORD. (Num 29:1-6)
I mentioned that the Hebrew calendar is a lunar calendar. That is not quite correct. A fully lunar calendar would be based solely on the phases of the moon that would cycle through the year, as the Islamic Calendar does. Instead, the Hebrew calendar is a lunisolar calendar. The twelve months add up to 354 days, so to keep up with the seasons extra, intercalary months are added in a nineteen-year cycle. Seven intercalary months are added during the cycle so that a thirteenth month is added every two or three years. This means that the dates wander a bit compared to the Gregorian calendar but stay within the appropriate seasons.
Anyway, Shana Tova everyone.
