In the Middle East, Christmas is a gift that keeps on giving. Christmas doesn't come just once a year but up to four times depending on how ecumenical you want to be. The Armenian churches outside the Holy Land celebrate on the Feast of the Epiphany, January 6. (Except in the Holy Land when they mark it in the Julian calendar.) Merry Christmas to those celebrating.
Most of the Orthodox Christian Churches, Oriental Orthodox, and the Church of the East celebrate Christmas on December 25 in the Julian Calendar, which currently equates to January 7 in the Gregorian, so a Merry Christmas to them tomorrow.
Fear not: it's still not over. Armenians in Jerusalem and Bethlehem will celebrate on August 18-19, Epiphany (known to Eastern churches as the Theophany) under the Julian calendar.
