The French days of the week are named which gods?

no, it's the planets (but you are right, planets depend on the Greeks gods)

Lundi -> Lune = moon

Mardi -> Mars

Mercredi -> Mercure = Mercury

Jeudi -> Jupiter

Vendredi -> Vénus = Venus

Samedi -> Saturne = Saturn

Dimanche -> Soleil (Dies in latin) = Sun I'm afraid you have made a mistake concerning 'Dimanche'. Obviously in English, Sunday is the day of the sun, but in French it's 'le jour du Seigneur' - the day of Our Lord -Di comes from the Latin dies, and dimanche comes from dies Dominicus.
