An anonymous work known as De Pascha Computus (243) linked the idea that creation began at the spring equinox, on March 25, with the conception or birth (the word nascor can mean either) of Jesus on March 28, the day of the creation of the sun in the Genesis account.
One translation reads: "O the splendid and divine providence of the Lord, that on that day, the very day, on which the sun was made, March 28, a Wednesday, Christ should be born.
In the Matthew account, magi follow a star to Bethlehem to bring gifts to Jesus, born the king of the Jews.
King Herod orders the massacre of all the boys less than two years old in Bethlehem, but the family flees to Egypt and later settles in Nazareth.
Early Christians celebrated the life of Jesus on a date considered equivalent to 14 Nisan (Passover) on the local calendar.
Because Passover was held on the 14th of the month, this feast is referred to as the Quartodecimal.
However, some Eastern Christian Churches celebrate Christmas on December 25 of the older Julian calendar, which currently corresponds to January 7 in the Gregorian calendar, the day after the Western Christian Church celebrates the Epiphany.
This is not a disagreement over the date of Christmas as such, but rather a preference of which calendar should be used to determine the day that is December 25.
In the Gospel of Luke account, Joseph and Mary travel from Nazareth to Bethlehem for the census, and Jesus is born there and laid in a manger.
It says that angels proclaimed him a savior for all people, and shepherds came to adore him.
The Nativity stories of Matthew and Luke are prominent in the gospels and early Christian writers suggested various dates for the anniversary.
