Planetary Hours

A system devised by ancient astrologers that assigned one of the seven planets then known to each hour of the day. The first hour of sunrise was ruled by the planetary day ruler (Sunday, Sun; Monday, Moon; Tuesday, Mars; Wednesday, Mercury; Thursday, Jupiter; Friday, Venus; Saturday, Saturn) and each hour thereafter governed by the next faster moving planet in rotation from Saturn to Jupiter, Mars, Sun, Venus, Mercury, Moon and back to Saturn throughout the twenty-four-hour period. Planetary energy was thought to be focused during the days and hours associated with a planet.
