The days of the week were named after Norse gods and giant objects in the sky.

These names come to us originally from the Greeks and Romans, who named the days of the week after their gods.

The Anglo-Saxons, who invaded Britain hundreds of years ago, adopted this idea but substituted their own gods. The English language has inherited and changed those names a bit, but the ones we use today resemble those names.

Here's how for Wednesday: 

Woden's Day. Woden, or Odin, was a Norse god who was one of the most powerful of them all.
