Christmas is an annual festival commemorating the birth of Jesus Christ. It is observed on December 25 as a religious and cultural celebration among billions of people around the world.
Easter, also Pascha or Resurrection Sunday, is a festival and holiday commemorating the resurrection of Jesus from the dead.
Easter Sunday is the Sunday following the paschal full moon date. The paschal full moon date is the ecclesiastical full moon date following 20 March. The Gregorian method derives paschal full moon dates by determining the epact for each year. The epact can have a value from * (0 or 30) to 29 days.
