Many of our contemporary customs and traditions are derived from pagan roots. People love to ascribe religious meaning to everything.
For example “Thursday” is derived from Old English Þūnresdæg and Middle English Thuresday, which simply means “Thor’s day.”
Wikipedia says “since the Roman god Jupiter was identified with Thunor (Norse Thor in northern Europe), most Germanic languages name the day after this god: Torsdag in Danish, Norwegian, and Swedish, Hósdagur/Tórsdagur in Faroese, Donnerstag in German or Donderdag in Dutch. Finnish and Northern Sami, both non-Germanic (Uralic) languages, uses the borrowing “Torstai” and “Duorastat”. (1)
