Tuesday (Tue or Tues) came from the Old English word Tiwes dæg. This was named after the Nordic god Tyr. Tyr was the God of War, like the Roman war god Mars, and Greek god Ares. In Latin, Tuesday is called Martis dies which means "Mars's Day".
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.
