Today is Onsdag, in English it's Wednesday, or Wodansday, and it was named for Odin. Odin is the father of the Norse gods, god of war, death, poetry and wisdom.
He was pierced with his own spear and was stuck to the tree of wisdom for nine days. He has only one eye which shines like the sun. The other eye he traded for a drink from the well of wisdom and thus gained all knowledge. He sits on throne in Asgard and can observe all that happens in the nine worlds.
On the day of Ragnorak, Odin will be swallowed by the wolf Fenrir.
