Sunday

The English noun Sunday derived sometime before 1250 from sunedai, which itself developed from Old English (before 700) Sunnandæg (literally meaning "day of the sun"), which is cognate to other Germanic languages, including Old Frisian sunnandei, Old Saxon sunnundag, Middle Dutch sonnendach (modern Dutch zondag), Old High German sunnun tag (modern German Sonntag), and Old Norse sunnudagr (Danish and Norwegian søndag, and Swedish söndag). The Germanic term is a Germanic interpretation of Latin dies solis ("day of the sun"), which is a translation of the Greek heméra helíou.

The first three epochs of the cosmos, the mineral, vegetable and animal eras - Saturn-day, Sun-day and Moon-day - are remembered in the names of the first three days of the week. These days of the week are named after these three heavenly bodies in this particular order for this reason alone.
