Saturnday

Ancient cultures everywhere observed seven “wanderers” move against the apparently fixed stars of the night sky: our star the sun, our natural satellite the moon, and the brightest planets Mars, Mercury, Jupiter, Venus, and Saturn. In many languages, these wanderers became the basis for the names of the seven days of the week; for example, in English & French the days are:

Sunday & dimanche
Monday & lundi
Tuesday & mardi
Wednesday & mercredi
Thursday & jeudi
Friday & vendredi
Saturday & samedi

In many languages, the days of the week are named after the classic "planets"
