Days of the week origin

Have you ever wondered what is the etymology of the weekday names? No? We neither. Apart from obvious Sunday, we didn't think about it before.

The Romans named the days after their gods and the celestial bodies such as Moon and Sun. Romance languages still resemble those names, but English names were filtered through ages by Germanic and Norse culture. Tuesday, Wednesday, Thursday and Friday names are influenced by their myths, but Moon, Sun and Saturn are still visible cores in remaining days' names:

Planet Latin Old English English Spanish French Italian
Moon Dies Lunae Mōnandæg
(Moon's day)
Monday lunes lundi lunedi
Mars Dies Martis Tīwesdæg
(Tiw's day)
Tuesday martes mardi martedi
Mercury Dies Mercurii Wōdnesdæg
(Wōden's day)
Wednesday miércoles mercredi mercoledì
Jupiter Dies Jovis Þunresdæg
(Þunor's day)
Thursday jueves jeudi giovedi
Venus Dies Veneris Frīgedæg
(Frigg's / Freya's day)
Friday viernes vendredi venerdì
Saturn Dies Saturni Sæternesdæg
(Saturn's day)
Saturday sábado samedi sabato
Sun Dies Solis Sunnandæg
(Sun's day)
Sunday domingo dimanche domenica
