Epiphany.
The Epiphany falls on January 06, twelve days after Christmas It is also known as 'the Manifestation of Christ to the Gentiles' so is related to Christmas.
The strong focus on the Visit of the Magi has been a feature of the Western Church only. In other traditions the revealing or the true nature of Christ has been focused on the Declaration made at his baptism in the Jordan and the revelation made at Carla in Galilee. Thus modern Anglican practice has been to make more prominent within Epiphany tide the Feast of Tile Baptism of the Lord as well as other aspects of making Christ known to the Gentiles.
