The celebration of Christmas comes to an end* with the feast of Epiphany. Epiphany, which means 'manifestation', celebrates the manifestation of God in human form. In the west this primarily commemorates the visit of the Magi to the Christ child; in the east the focus is on Christ's baptism, where the Spirit descended on him as a dove and the voice of the Father declared his sonship.
Topsy Creatori(StoveTop nomore!) made these Magi.
Rogue Warrior made this John the Baptist.
*In some places Christmas traditionally lasts 12 days, from December 25 to January 5. In others there is a 40 day season, ending with Candlemas on February 2. Also worth noting, the Gregorian calendar was introduced in 1582, to correct for differences between the solar and calendar year. Some in the east still follow dating due to the earlier Julian calendar, which places Christmas on January 7. So you can still call someone in the Ukraine tomorrow and wish them a merry Christmas.
