Duration of Mercury Retrograde motion = 69 Days
Notes: All timings are represented in 12-hour notation in local time of Columbus, United States with DST adjustment (if applicable).
Hours which are past midnight are suffixed with next day date. In Panchang day starts and ends with sunrise.
Before Mercury becomes retrograde it enters into retrograde zone and starts slowing down. Before it becomes stationary and starts moving into backward direction, it keeps moving into forward direction with retarded speed. Mercury remains into stationary motion for some moments before it starts moving backward. The time when Mercury just starts moving backward is noted down during our calculations.
The same is true while Mercury becomes progressive i.e. when it starts moving into forward direction. Before Mercury becomes progressive it remains into retrograde zone and starts moving into forward direction till it gains full speed. The time when Mercury just starts moving into forward direction (gaining full speed and leaving retrograde zone takes some more time) is noted down during our calculations.
In sum, each retrograde zone has four points namely, Shadow, Retro Station, Direct Station and Release. We list only Retro Station and Direct Station for Mercury.
