There was a giveaway thread guessing the game, but I cannot find it now

Settlers 4 :p

That would be my guess too. :-D

Is it really Thor's day? I'm being serious. I know Westerners have kind of trivialized his existence but once upon a time he was quite the social and spiritual icon.

There are a lot of Scandinavians where I live (well descendants of Scandinavians) so you still see a lot of Thor stuff around here regarding the myths and legends.

Here you go ;)

Thought it was Zeus day, because he did thunder,and its called Thunderday here.

and the lucky winner is.... le_chevalier :)

Yes. That's were the name Thursday (Thorsday) comes from. Just like Friday was devoted to Freia. And Wednesday to Wodan.

. It is in French. The romanic names of course hark back to the Greco/Roman gods, not the Norse ones, So Jeudi comes from Jove (Jupiter = Zeus), like Mardi comes from Mars and Mercredi comes from Mercur and Vendredi/Veneredi comes from Venus.

The German Donnerstag however stems from Donar, which is just another name for Thor.

Jep. Mjölnir is the historical name of the hammer. And actually Thor used to throw lightnings too, Being the god of thunderstorms (among other duties) this somehow fell in his job description.
Yes, it is. English has lots of Latin influences so it is a mixed bag language. Thus Saturday bears a Roman god in its name. And Sunday and Moonday, Lun(e)di in French, are just days dedicated to Moon and Sun, as you correctly stated.

The Swedish word for Thursday is "torsdag" which literally means "Thor's day", although a modern Swede talking about Thor's Day (as a holiday or something, instead of the idiomatic weekday name) would probably spell it separately ("Tors Dag") because that's how the grammar works these days. Almost all Finns must take Swedish at school, and even though I did really rather poorly there and honestly cannot fathom our language policy, I'm fairly sure that I got that correctly. Just don't quote me on that until my words have been busted or confirmed by a proper Viking.

The Finnish word for Thursday ("torstai") has been borrowed from Swedish but doesn't mean anything. Not that anyone cares.

I used to use the Sailor scouts to remember the Spanish days of the week:
Moon - Lunes
Mars - Martes
Mercury - Miércoles
Jupiter - Jueves
Venus - Viernes
and Sábado and Domingo were easy enough to remember on their own. :)

Why do they call Wednesday "Hump Day" when most people get laid on the weekends?

You get Viking approval on that one. =P I thought the language requirement was abolished quite a few years back, though? Is it back or am I just misremembering?
