Saturday is the day of the week between Friday and Sunday. The Romans named Saturday Sāturni diēs no later than the 2nd century for the planet Saturn, which controlled the first hour of that day, according to Vettius Valens. The day's name was introduced into West Germanic languages and is recorded in the Low German languages such as Middle Low German sater(s)dach, Middle Dutch saterdag and Old English Sætern(es)dæġ and Sæterdæġ. In Old English, Saturday was also known as sunnanæfen.
