Ephesians
5.16:
Making the very most of the time [buying up each
opportunity], because the days are evil.
Psalm 118.26:
This is the day which the LORD has brought about; we will
rejoice and be glad in it.
Every hour of every day has its genie, or guardian angel, and every days was ruled by one of the pantheon of divine beings who were worshipped under various names in the pagan world.
The name of the days still celebrate their ancient guardians, which were identified with the planetary lords and ladies:
Sunday, ruled by the Sun.
Monday, ruled by the Moon.
Tuesday, ruled by Mars (Tiw, the ancient saxon god of war was equivalent to Mars in the Roman Pantheon, cf. Mardi in French and similarly in other latin-derived tongues.
Wednesday (Woden's day), the saxon Mercury, cf. mercredi in French.
Thursday (Thor's day), the king of the gods, equivalent to Jupiter, Jeudi in French.
Friday, Freya's day (the saxon Venus, cf. French Vendredi).
Saturday, ruled by Saturn.
And above all those, Jesus Christ is the maker of the days. Have a good days in the Lord!
