Mercury stations retrograde on March 26, 2077 at 20° Aries, and direct on April 18 at 8° Aries — 23 days. From the Earth, Mercury seems to back up against the stars as we overtake it, as a car passed on the highway seems to slide backward. Astrology holds it a time for crossed wires and delays. Computed from JPL's approximate orbits; the stations agree with an almanac's to within minutes.
