Acually, most days are named after Nordic gods...
Übereil
That rings a bell. I think they've all been translated over time though. I'm pretty sure Sunday is named after a Sun God.
Really?
I find it hard to imagine the following week:
Thorday Lokiday Odinday Friggday Helday Balderday Fenrirday
Try saying them out loud...
Thorday = Thursday
Friggday = Friday
I'm sure one of Loki and Odin is Monday. I must look this up...
