How did we get our weekday names?

The following is what I could dig up.
 

In ancient Rome the weekdays got their names from planets, the moon, and the sun. The ones we still use today are...

• Saturday - from the planet Saturn

• Sunday - Sun day - Old Norse sunna = sun.

• Monday - The day of the Moon

The rest of our days, it seems, comes from their Norse counterparts...

• Tuesday - Tyr's day: the Old Norse God of war (also Tiw's day)

• Wednesday - Wooden's day (also Odin's day: Odin was the most powerful God of all in the Norse mythology)

• Thursday - Thor's day: Thor was the second greatest God after Odin. He is mostly known for his hammer with which he made thunder and lightning, and for his two birds, Hugin and Munin. (see below)

• Friday - The Roman love goddess Venus has her counterpart in the Nordic Freya; Old Norse Frigg and Freyja.

I stand corrected! The following notes are from a visitor...

I'm sure I'm not the first to point it out, but the "birds" Hugin and Munin, associated with Thor in your "Days of the Week" article, are actually Odin's ravens "Thought & Memory". As such, they have absolutely no association with Thor. He does, however, have an interesting pair of goats that pull his thunder chariot........... Cheers
