Days of the Week…it’s all a bit greek to me.

I have been sitting during this sunny day, and whilst talking to a friend, we ended up discussing the origins of the names of the days of the week.

So off to the land of searching we went…and after clicking on several entries on the search results page, we can across this;

The Greeks named the days of the week after the sun, the moon and the five known planets, which were in turn named after the gods Ares, Hermes, Zeus, Aphrodite, and Cronus. The Greeks called the days of the week the Theon hemerai “days of the Gods”. The Romans substituted their equivalent gods for the Greek gods, Mars, Mercury, Jove (Jupiter), Venus, and Saturn. (The two pantheons are very similar.) The Germanic peoples generally substituted roughly similar gods for the Roman gods, Tiu (Twia), Woden, Thor, Freya (Fria), but did not substitute Saturn.
