 However, the "Lutheran Book of Worship" does permit the celebration of a Lesser Festival on Sundays where the normal color of the day would be green (that is, seasons after Epiphany or after Pentecost) or on the Sundays in Christmas.This is abrogated for patronal festivals (that is, the day commemorating the saint or event for which a congregation is named) provided that they do not take place in Lent, Advent, or Easter, in which case they must also be transferred to the next convenient weekday.Most Lesser Festivals have their own collects and a few, such as All Saints, have their own proper.
