- That's right. Numbers 28:16 provides for the Passover sacrifice to
- be made on the fourteenth day of "the first month," and for the
- seven-day Feast of the Passover to commence on "the fifteenth day
- of this month." Exodus 12:2 and 13:4 make it clear that "the first
- month" is the month that was known as "Abib" (= "Spring") in
- pre-Exilic times, such as the times when the "books of Moses" --
- including Exodus and Numbers -- were written. After the Babylonian
- Exile, the Jews started using the Babylonian names for the lunar months.
- See Esther 3:6: "In the first month, which is the month Nisan, . . ."
- Because lunar months begin with the New Moon and last 29 or 30 days,
- the "fifteenth day of this month" is the day of the Full Moon -- the
- first Full Moon after Spring begins at the Vernal Equinox.
-
- Whatever it is called, the month in which the Passover feast occurs
- has to come in the Spring ("Abib"), i.e., *after* the Vernal Equinox.
- If it became apparent to the Sanhedrin that twelve lunar months would go
- by since the previous year's "first month" and it would still be Winter,
- why, they'd just proclaim the addition of a thirteenth lunar month to
- that year, so that the new year's "first month" would begin during the
- Spring.

- This, too, is right, which is why they have "Russian Easter" in the
- Orthodox Church. In the West, Easter Sunday usually does indeed
- fall close to the Passover. But not *too* close: the "Easter Rule"
- ensures that if the 15th day of Nisan -- the first Full Moon after
- the Vernal Equinox -- occurs on a Sunday, Easter itself will be
- relocated to another Sunday. In this way, the rule keeps the
- celebration of the resurrection from coinciding with the beginning
- of the Jewish Passover feast.
-
- Hope this helps.
