The content of the liturgical calendar (like the content of the liturgy itself) was the responsibility of territory in which the church was found. Thus, there was a different order for Saxony, one for Prussia, one for Hesse, and one for Wittenberg, among others. Despite their differences, the calendars and liturgies maintained significant similarities between each other as well as the calendar of the Roman Catholic Church. The church year continued to begin with the First Sunday of Advent (which was still fixed based on the traditional formula), and many of the festivals surrounding Christmas (St. Stephen, St. John, the Holy Innocents) remained in place, even if they were often ignored. Epiphany also continued to be celebrated as the visit of the Magi, though Martin Luther preferred to commemorate the baptism of Christ.
