The liturgical calendar is the cycle of the church year, which dictates when churches celebrate certain major events, according to Central Baptist Theological Seminary in Shawnee, Kansas. The liturgical calendar follows the life of Jesus Christ and the creation of the Christian church.
The liturgical calendar begins with Advent, the four weeks leading up to Christmas and the birth of Jesus. January 6th marks Epiphany, which commemorates the date when the Three Magi visited baby Jesus. Lent leads up to Holy Week and Easter, when Christians celebrate the resurrection of Jesus. After Easter, the church marks the time of Pentecost, when the original Christian church was founded following the death of Jesus.
