1._____________
Do you know how the days of the week get their names? There was a time in the early history of man when the days had no names! The reason was quite simple：men had not invented the week.
2. _____________
In those days, the only division of times was the month, and there were too many days in the month for each of them to have a separate name. But when men began to build cities, they wanted to have a special day on which to trade, a market day. Sometimes these market days were fixed at every tenth day, sometimes every seventh or every fifth day. The Babylonians decided that it should be every seventh day. On this day they didn't work, but met for trade and religious festivals.
3. _____________
The Jews followed their example, but kept every seventh day for religious purposes. In this way the week came into existence. It was the space between market days. The Jews gave each of the seven days a name, but it was really a number after the Sabbath day(which was Saturday). For example, Wednesday was called the fourth day (four days after Saturday)．
4. _____________
When the Egyptians adopted the seven­day week, they named the days after five planets, the sun, and the moon. The Romans used the Egyptian names of their days of the week: the day of the sun, of the moon, of the planet Mars(火星), of Mercury(水星), of Jupiter(木星), of Venus(金星), and of Saturn(土星)．
5. _____________
We get our names for the days not from the Romans but from the Anglo­Saxons, who called most of the days after their own gods, which were roughly the same as the gods of the Romans. The day of the sun became Sunnandaeg, or Sunday. The day of the moon was called Monandaeg, or Monday. The day of the Mars became the day of Tiw, who was their god of war. This became Tiwesday, or Tuesday. Instead of Mercury's name, that of the god Woden was given to Wednesday. The Roman day of Jupiter, the thunderer, became the day of the thunder god Thor, and this became Thursday. The next day was named for Frigg, the wife of their god Odin, and so we have Friday. The day of Saturn became Saeterndaeg, a translation from the Roman, the Saturday.
