In the north west of England, church and chapel parades called Whit Walks take place at Whitsun (sometimes on Whit Friday, the Friday after Whitsun). Typically, the parades contain brass bands and choirs; girls attending are dressed in white. Traditionally, Whit Fairs (sometimes called Whitsun Ales) took place. Other customs such as morris dancing and cheese rolling are also associated with Whitsun. "Whitsunday" has been the name of the day in the Church of England. (The Book of Common Prayer only once uses the word "Pentecost" for the festival. Though some think that name derives from white clothes worn by newly baptised in Eastertide, it may well be seen as derived from "wit", hence "wisdom", the reference being to Holy Wisdom (Sancta Sophia, Hagia Sophia), referred to in Proverbs and the Book of Wisdom, with which the Holy Spirit has often been identified.
