The weekly horoscopes for September 21 are up. We have Saturn recently in Sagittarius and Mercury has just gone retrograde in Libra. This week the Sun will move into Libra and Mars will move into Virgo. With Mars and Saturn both freshly in mutable signs, they are also forming a square. While Saturn has been traditionally referred to as the heavy “Taskmaster”, Mars in Virgo immediately calls to mind a position with potential for refined and energized execution of tasks.
