Easter and the holidays that are related to it are movable feasts which do not fall on a fixed date in the Gregorian or Julian calendars which follow only the cycle of the sun; rather, its date is determined on a lunisolar calendar similar to the Hebrew calendar. (Wikipedia)
How come that Lent moves around while Christmas stays put?
From Daniel Engber, columnist for Slate:
Because the church said so in A.D. 325. The date of Easter is determined according to the lunar calendar, while the date of Christmas is fixed on the solar calendar. Before 325, there was no official celebration of the birth of Christ, and Easter was celebrated by some Christians on Passover (a lunar holiday) and by others the following Sunday. The rationale: Christ's last supper took place on or around Passover, he was crucified on a Friday, and the festival of Easter celebrates his resurrection two days later.
But what if, indeed, last year's Christmas was to be our last Christmas as both Pope Francis and Queen Elizabeth have been widely reported to have stated last year?
It's going to be the first celebration of Jesus' true Birthday then!
Then we could say with heartfelt and soul-stirring remembrance,
"Thank you for coming into our lives Yeshua!"
Christ's real birthday
Jonathan Cahn is a Messianic Jewish Rabbi and pastor best known for his best selling novel The Harbinger, in which he compares the United States and the September 11 attacks to ancient Israel and the destruction of the Kingdom of Israel. In particular, he sees Isaiah 9:10 as a prophetic warning to the United States.
Cahn has addressed the UN a few times, the last one on March 2, 2016, when he spoke at the UN-Symposium on Peace, Reconciliation, Sustainable Development and Multicultural Understanding.
In the video below he directly answers many questions related to the Birthday of Jesus. Excerpts:
Cahn: It would change on our calendar every year, but it's gonna be in spring, it's gonna be March, April, and it's gonna be Nisan 1. You could find out Nisan 1 every year. In fact Nisan 1 is the true New Year for Jewish people, but Jews don't celebrate it because they think Rosh Hashanah* is.
*Rosh Hashanah is the anniversary of the creation of Adam and Eve.
Astonishing revelation: Jonathan Cahn brings forward proof that Messiah Jesus (Yeshuah) was born in spring. Why and when exactly?
Jonathan Cahn the Messianic Jewish Rabbi best known for his best selling books "The Harbinger" (2012) and "The Mystery of the Shemitah," (2014) has now released a documentary film called The Mishkan Clue" -- a quest to solve the mystery of the date of Christ's birth.
