The 10 commandments measure time in the same way as the creation story. Six days of work and then the day of rest are mentioned, with the seventh day being called the Sabbath.

Ex 20:8-11 8 "Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it."

In the next "Calendar of Evidence," the significance of the 7th day during the last week of Jesus' life on earth is examined.
