Etymology

Old English thursdæg, from early Norse thōrsdagr, literally "day of Thor"

Word Origin
Among the many gods worshiped by the Germanic people who lived in northern Europe in ancient times was one whose name was Thor. Thor was the god of thunder, weather, and crops. In the early Norse language, the fifth day of the week was known as thōrsdagr, literally "day of Thor," in his honor. The Norse name came into Old English as thursdæg, which in time became the Modern English Thursday.
