 However, the Lutheran calendar differs from both in two very significant ways, aside from its emphasis on commemorating persons important to the Lutheran tradition.First, the Lutheran calendar, while commemorating many of the same events or persons, often does so on different days from either calendar (St. Cyprian of Carthage on September 16 for Lutherans, but September 13 in the Episcopal Church).In other cases (such as St. Valentine on February 14), individuals who have long standing within Western Christianity are not mentioned in the Lutheran calendar, or are only mentioned in the calendars of some Lutheran churches.
