Sunday is the day of the week between Saturday and Monday. It gets its name from Sunne, the Saxon Sun god, or Sunna the Scandinavian Sun goddess.

Sunday is sometimes held to be the last day of the week (especially in modern Europe), and sometimes the first day (a traditional view derived from ancient Jews and ancient Egyptians).

In the popular rhyme, "Sunday's Child is fair and wise, and good and gay".

In ancient Jewish tradition Saturday is the sabbath. Many languages lack separate words for "Saturday" and "sabbath". Eastern Orthodox churches distinguish between the sabbath (Saturday) and the Lord's day (Sunday). Roman Catholics put so little emphasis on that distinction that many among them follow -- at least in colloquial language -- the Protestant practice of calling Sunday the sabbath.
