Mercury retrograde is a term used in astrology to describe a period of time when the planet Mercury appears to move backward in its orbit around the sun. This happens due to an optical illusion caused by differences in orbit, and it occurs about three to four times a year for about three weeks at a time. During this period, astrologers believe that the areas of life ruled by Mercury, such as communication and travel, can be disrupted, leading to frequent misunderstandings, scheduling problems, and disagreements with friends. Some people also believe that technology and communication could get disrupted during this period. However, scientists say that retrograde motion has no actual effect on our lives apart from the optical illusion.

Mercury retrograde is not a new concept and has been observed by astronomers for centuries. In 2023, Mercury retrograde is set to take place four times: from April 21 to May 14, August 23 to September 15, December 13 to January 1, 2024. While some people believe that Mercury retrograde is a time of misfortune, others see it as an opportunity to reflect, reassess, and plan for the future.
