Lutheran liturgical calendar

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 the Lutheran Church–Missouri Synod (LCMS) and the Lutheran Church–Canada (LCC) use the Lutheran Book of Worship and the 1982 Lutheran Worship.
