From *Sāturnas, *Saturnas (“Saturn's”) + *dag (“day”), calque of Latin diēs Sāturnī (“Saturday”, literally “day of Saturn”). The Old English form appears to descend from a variant form *Saturnas dag (with short a), as one would otherwise expect sǣternesdæg.
In all (modern) High and most Low German dialects, other words for Saturday are found instead which commonly refer to Sunday or the Sabbath day, e.g. Old High German sambaztag (literally “Sabbath-day”) (modern German Samstag), and Old High German sunnūnāband (literally “Sunday eve”) (modern German Sonnabend) (see also Old English sunnanǣfen (“evening before Sunday”) and Old Norse sunnunótt (“night before Sunday”)).
