Where Did the NAMES of the DAYS of the WEEK Come From? AND Why You Love FRIDAY!

The Babylonians named the days after the five planetary bodies known to them (Tuesday through Saturday).

And after the Sun and Moon (Sunday and Monday).

This custom was later adopted by the Romans. Emperor Constantine established the seven-day week in the Roman calendar in 321 and designated Sunday and Monday as the first two days of the week.

The other weekday names in English are derived from Anglo-Saxon names for gods in Teutonic mythology.

Tuesday comes from Tiu, or Tiw, the Anglo-Saxon name for Tyr, the Norse god of war.

Tyr was one of the sons of Odin, or Woden, the supreme deity after whom Wednesday is named.

Similarly, Thursday originates from Thor, the god of thunder.

Friday is derived from Frigga, the wife of Odin, representing "love" and beauty.
