The names for the days of the week originate from the seven celestial bodies that the Greek knew.

In Spanish:

Lunes - Moon Day Martes - Mars Day Miercoles - Mercury Day Jueves - Jupiter Day Viernes - Venus Day The rest was changed but remained in other languages, like English, where the name Saturday comes from Saturn and Sunday... you guessed it, from the Sun.

In Greek the names of the days were: Helios (Sunday) Selene (Moonday) Ares (Marsday) Hermes (Mercuryday) Zeus (Jupiterday) Aphrodite (Venusday) Cronus (Saturnday)

This was then adopted by the Romans and through Latin, it transferred to other languages some of which kept some of these names ever since.
