was replaced by [dies] Dominicus (Dominica), that is, "the Lord's Day", and of Saturday, which was named for the Sabbath. Mirandese and Modern Portuguese use numbered weekdays (see below), but retain sábado and demingo/domingo for weekends. Celtic languages Early Old Irish adopted the names from Latin, but introduced separate terms of Norse origin for Wednesday, Thursday and Friday, then later supplanted these with terms relating to church fasting practices. Adoptions from Romance Albanian adopted the Latin terms for Tuesday, Wednesday and Saturday, adopted translations of the Latin terms for Sunday and Monday, and kept native terms for Thursday and Friday. Other languages adopted the week together with the Latin (Romance) names for the days of the week in the colonial period. Several constructed languages also adopted the Latin terminology. With the exception of sabato, the Esperanto names are all from French, cf. French dimanche, lundi, mardi, mercredi, jeudi, vendredi.

The date of the introduction of this system is not known exactly, but it must have happened later than CE 200 but before the introduction of Christianity during the 6th to 7th centuries, i.e., during the final phase or soon after the collapse of the Western Roman Empire. This period is later than the Common Germanic stage, but still during the phase of undifferentiated West Germanic. The names of the days of the week in North Germanic languages were not calqued from Latin directly, but taken from the West Germanic names. Sunday: Old English (), meaning "sun's day". This is a translation of the Latin phrase . English, like most of the Germanic languages, preserves the day's association with the sun. Many other European languages, including all of the Romance languages, have changed its name to the equivalent of "the Lord's day" (based on Ecclesiastical Latin ). In both West Germanic and North Germanic mythology, the Sun is personified as Sunna/Sól. Monday: Old English (), meaning "Moon's day". This is equivalent to the Latin name . In North Germanic mythology, the Moon is personified as Máni. Tuesday: Old English (), meaning "Tiw's day". Tiw (Norse ) was a one-handed god associated with single combat and pledges in Norse mythology and also attested prominently in wider Germanic paganism. The name
