Christian feast day: William of Ockham (Anglicanism)

William of Ockham or simply Occam was an English Franciscan friar, scholastic philosopher, apologist, and theologian, who was born in Ockham, a small village in Surrey. He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the 14th century. He is commonly known for Occam's razor, the methodological principle that bears his name, and also produced significant works on logic, physics and theology. William is remembered in the Church of England with a commemoration corresponding to the commonly ascribed date of his death on 10 April.

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.
