Thursday an English word is named after the Norse god of thunder, Thor. Thursday means Thor's day in Old English. Thor is represented riding a chariot drawn by goats and wielding the hammer. In most languages with Latin origins, the day is named after the god and planet Jupiter."
The legal working week (British English), or workweek (American English), is the part of the seven-day week devoted to labour. In most of the Western world, it is Monday to Friday; the weekend is Saturday and Sunday. In some Christian traditions, Sunday is the "day of rest and worship".
Traditionally, it is believed that a 5-day work week is more productive. A 6-day work week stresses people out and doesn't give them enough time to spend with their families. The week seems too long and the weekend seems too short, and there is an imbalance with five days of stress and two days of recreation.
