> That sounds quite sensible. From memory, our (en_GB) weekdays are named like this:

Spanish and English follow a similar day naming convention.

But the god's name needs to be translated from Norse Mitology to Roman Mitology first [1]

Lunes/Monday -> Moon/Luna

Martes/Tuesday -> Tiw/Mars

Miercoles/Wednesday -> Woden/Mercury

Jueves/Thursday -> Thunraz/Jupiter

Viernes/Friday -> Frig/Venus

Sábado/Saturday -> Saturn/Saturno

With the exception of Saturday. Tacitus associated the Hebrew sabbath («sábado») with Saturn, but the word for the day itself is not «saturno» as it would be if it were like English.

I'd always thought (though I don't have a specific source I can recall), that the seven days of the week was drawn from the seven non-fixed celestial bodies visible ot the naked eye: the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn. The planets were frequently associated with and named after deities, so the days of the week also have the names of deities.

Friday literally means Day of Frigg (Old English), referring to Frigga, the wife of Odin. Yes, Freya is believed to be the same goddess as Frigga, but the day is named after Frigga not Freya.

Thurday would probably be 'Þunor's Day' instead of Thor as it's Old English :)
