In most cultures which have a seven-day week, either Saturday or Sunday is the traditional day of rest, and Friday for most countries of the Middle East. Yet in countries such as Australia, U.S. and UK the weekend is considered Friday night, Saturday and Sunday, with the workweek beginning on Monday.
The American concept of the weekend has its roots in labor union attempts to accommodate Jewish workers who took Saturday instead of Sunday as their Sabbath. The first five-day work week was instituted by a New England cotton mill for this reason.
In 1926 Henry Ford began shutting down his automotive factories for all of Saturday and Sunday. In 1929 the Amalgamated Clothing Workers of America was the first union to demand a five-day work week and receive it. After that, the rest of the United States slowly followed, but it wasn't until 1940 that the two-day weekend began nationwide.

<snip>Imagine what you could do with an extra 52 days off each year. With a four-day workweek: • More jobs might be created, by businesses that must be open certain hours. • Companies closed an extra day each week would save on janitorial services, energy bills and increasing security costs. • As stress falls, so might disability claims. • There would be less absentee time, as employees could schedule doctor and personal appointments on their extra day off. • Morale would improve, which always benefits productivity.
