Wednesday derives it's name from two mighty but distinct gods. The Old English word for Wednesday indicates that the day was named for the Germanic god Woden. In Romance languages, the name is derived from the Roman god Mercury. (For example, Wednesday is mercredi in French and miercuri in Romanian.)"
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.
