Sabbath

On the first day God created light; on the second, the firmament of heaven; on the third, he separated water and land, and created plant life; on the fourth day he created the sun, moon, and stars; on the fifth day marine life and birds; on the sixth day land animals, and man and woman. On the seventh day, the Sabbath, God rested, and sanctified the day. http://en.wikipedia.org/wiki/Genesis
