When Lutherans came to North America, they brought with them their disparate liturgical traditions. The Pennsylvania Ministerium composed the first liturgy for North America, including its calendar along somewhat minimal lines. However, since the last quarter of the nineteenth century, the calendar within North American Lutheran churches has been expanding. In 1868, four chief festivals in the "Church Book" were Christmas, New Year’s Day, Epiphany, and Reformation Day, with Easter and Pentecost being considered a separate category because they invariably fell on Sunday. The "Church Book" also included several minor festivals, including festivals for all the Apostles, and the Annunciation. The "Common Service Book" (1918) also expanded the calendar to help congregations determine which days took priority over others in cases of coincidence. It added to the calendar the Sundays of Advent, Transfiguration (last Sunday after Epiphany), Septuagesima, Sexagesima, Quinquagesima, Ash Wednesday, Sundays in Lent, all days in Holy Week, Ascension and the following Sunday, and Holy Trinity. It also included All Saints, and Saints Mark and Luke, both of which were omitted from the "Church Book". The "Service Book and Hymnal" (1941) also moved the Transfiguration to August 6 and added Holy Innocents to the calendar.
