Mercury retrograde
Retrograde Mercury describes the interval when Mercury’s apparent position moves backwards in zodiacal longitude from Earth’s perspective.
How it is defined
It results from planets’ relative motion. It is not evidence that Mercury causes malfunctions, communication errors or personal breakups.
How to read it
To check the phenomenon, distinguish the calculated position, its reference time and what an observer can see from their location. These related details answer different questions.
A concrete example
