Friday is derived from the Old English frīġedæġ, meaning the “day of Frig”,  the Norse goddess of the hearth, home and fertility and wife of Odin, Frigg

Again, as in other modern countries that were part of the Roman empire, variations in the Latin dies Veneris or “day of Venus” is found in vendredi in French, venerdì in Italian, vineri in Romanian, and viernes in Spanish.

An exception is European Portuguese (Paul will have to tell us whether the Brazilians and Jim the Mozambicans do this), who use the word  sexta-feira, meaning “sixth day of liturgical celebration”,
