We saw his star at its rising and have come to do him homage. (Matthew 2:2)
Epiphany Sunday in most Christian liturgical calendars is celebrated on the nearest Sunday after January 6, the traditional observed day of the Epiphany. The Catholic Church will celebrate if it falls on a Sunday or on a Sunday between January 2 and January 8. Since Eastern Orthodox uses the Julian calendar, it will occur 13 days later. Epiphany or Three Kings Day is to celebrate the arrival of The Magi (Three Kings or Wise Men). During the Middle Ages, this was a major feast day (a solemnity) requiring attendance at church on that day. However as many people had to work it became more difficult to attend, the Catholic Church decided to make it easier for people to attend on Sunday, when most do attend church. Some Protestant churches celebrate the Epiphany season from January 6 till Ash Wednesday.
