Today is…Orthodox Christmas Day
It was also National Weigh In Day, or National Pass Gas Day. I thought this to be safer. 
Orthodox Christmas Day is observed by many Eastern Orthodox Christians to celebrate the birth of Jesus, who they believe to be the son of God. In many ways the day is observed similarly to how Western Churches observe Christmas Day, but there are some differences.
Orthodox Christmas Day takes place when it does because many Eastern Orthodox Churches follow the Julian calendar instead of the more adhered to Gregorian calendar. They still celebrate Christmas on December 25, but until 2100, December 25 on the Julian calendar is the same as January 7 on the Gregorian calendar. After 2100, Orthodox Christmas Day will take place on January 8 of the Gregorian calendar. This will be so because leap days are dropped in certain centennial years on the Gregorian calendar. Many Orthodox Christians in East and Central Europe follow the Julian calendar, as do various Orthodox Churches in the United States, such as the Russian, Ukrainian, and Serbian. Orthodox Christmas Day is a public holiday in some countries, but not in the United States.
The activities and foods of Orthodox Christmas Day vary by church and country. Many Orthodox churches fast the day before Orthodox Christmas, as a way to prepare for Jesus’ birth. Focus is shifted off of food, and is instead on prayer and caring for the poor. Usually meat and dairy products are excluded during the fast.
