Christian feast day: Martin Luther (Anglican Communion)

Martin Luther was a German priest, theologian, author, hymnwriter, professor, and former Augustinian friar. Luther was the seminal figure of the Protestant Reformation, and his theological beliefs form the basis of Lutheranism. He is widely regarded as one of the most influential figures in Western and Christian history.

The Church of England commemorates many of the same saints as those in the General Roman Calendar, mostly on the same days, but also commemorates various notable Christians who have not been canonised by Rome, with a particular though not exclusive emphasis on those of English origin. There are differences in the calendars of other churches of the Anglican Communion.
