The Epiphany Of Our Lord Jesus Christ - 6 January

Quoted from Catholic Action [1]

Epiphany is a Feast Day within the Church’s liturgical celebration of Christmas. In the current Western tradition, we associate it with the “Visit of the Magi,” or visitors from the East recounted in Matthew’s Gospel. (Mt 2:1-12). Epiphany is traditionally celebrated the 12th day after Christmas, (Twelfth Night), January 6th.... 

Epiphany takes its name from the Greek epiphania, a manifestation. Jesus, born quietly in Bethlehem’s stable, is revealed, or made manifest, as the Son of God.  In the recognition of Him by the Magi, the Christ, He is revealed to the “nations.” (see, for example, Is 42:6; Is 60: 1-6; and Psalm 72:11)

Quoted from Catholic Culture [2]:

The Solemnity of the Epiphany is celebrated either on January 6 or, according to the decision of the episcopal conference, on the Sunday between January 2 and January 8.  [The Sunday between January 2 and January 8 this year, 2022, was January 2.]
