Liturgical calendar (Lutheran)

The Lutheran liturgical calendar is a listing which details the primary annual festivals and events that are celebrated liturgically by various Lutheran churches. The calendars of the Evangelical Lutheran Church in America (ELCA) and the Evangelical Lutheran Church in Canada (ELCIC) are from the 1978 Lutheran Book of Worship and the calendar of Lutheran Church - Missouri Synod (LCMS) and the Lutheran Church - Canada use the Lutheran Book of Worship and the 1982 Lutheran Worship. Elements unique to the ELCA have been updated from the Lutheran Book of Worship to reflect changes resulting from the publication of Evangelical Lutheran Worship in 2006. The elements of the calendar unique to the LCMS have also been updated from Lutheran Worship and the Lutheran Book of Worship to reflect the 2006 publication of the Lutheran Service Book.

The basic element to the calendar is Sunday, which is a festival of Jesus’ resurrection. However, Christian Churches have historically observed other festivals which commemorate events in the life of Jesus or of significant individuals in the history of the Church. The purpose of the liturgical calendar is to guide commemorations as a part of the daily worship of the Lutheran Church. There is some variation associated with the observance of the calendar, as each Lutheran Church creates its own calendar and each congregation must choose independently how many individuals will be commemorated within a given year and how many festivals and lesser festivals they will publicly celebrate, especially if they do not coincide with a Sunday.

The Lutheran calendar operates on two different cycles: the Temporal Cycle and the Sanctoral Cycle. The Temporal Cycle pivots on the festivals of Christmas and Easter. All Sundays, Seasons, and Festivals are related to these festivals. Because Easter varies in date each year based on the vernal equinox and the phases of the moon, it is called a moveable feast (see: Computus). Dates affected by placement of Easter include Ash Wednesday and the start of Lent, the start of Easter itself, Pentecost, and Holy Trinity.Advent, the other pivotal season on the calendar, comes exactly four Sundays before the start of Christmas (if Christmas falls on a Sunday, that day does not count), or the Sunday closest to St. Andrew's Day (November 30). Like the other Western Church calendars, the first Sunday of Advent is also the first day of the liturgical year. The Sanctoral Cycle is the fixed daily commemorations of individuals and events not related to the Temporal Cycle of Sundays, Festivals, and Seasons. It is the Sanctoral Cycle which is sometimes thought of as being the “Calendar of Saints” of a Church.
