Saturdays: (Sat or Saturday) The Norse name for the planet Venus was Friggjarstjarna, 'Frigg's star'. It is based on the Latin dies Veneris, "Day of Venus". Saturday: the only day of the week to retain its Roman origin in English, named after the Roman god Saturn associated with the Titan Cronus, father of Zeus and many Olympians.
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.
