Where does whit Monday get its name from?

Whit Monday, also known as Pentecost Monday, derives its name from "Whitsun" or "Whitsunday," which is an Old English term for the Feast of Pentecost, celebrated 50 days after Easter. The term "Whit" comes from the Old English Word "hwita," meaning "white," referring to the white garments worn for baptisms during this time. The day is observed as a Christian holiday in many countries, marking the descent of the Holy Spirit upon the apostles.
