“Behold, the days are coming, declares the Lord, when I will fulfil the promise I made to the house of Israel and the house of Judah.  In those days and at that time I will cause a righteous Branch to spring up for David, and he shall execute justice and righteousness in the land.  In those days Judah will be saved, and Jerusalem will dwell securely. And this is the name by which it will be called: ‘The Lord is our righteousness.’

Jeremiah 33

Orthodox Christmas Day is on January 7 every year. Christmas was originally celebrated 13 days after December 25 (the day we celebrate it on today).  In the Julian calendar — a much older calendar used before the current Gregorian calendar — Christmas was celebrated on January 7.  The Orthodox Church still uses the same old calendar to celebrate Christmas Day.  Orthodox Christians celebrate by going to church and other traditions like burning frankincense to commemorate the Wise Men’s gifts to baby Jesus.
