Frequently asked questions
What does my Mercury sign mean?
Mercury describes how you think, learn, speak and process information. Astrologers read it for communication style, curiosity and the way you make decisions.
Can my Mercury sign be different from my Sun sign?
Yes, but not by much. Mercury never strays more than about 28° from the Sun, so it is either in your Sun sign or in the sign just before or after it.
Do I need my birth time?
Rarely. Mercury spends two to eight weeks in each sign. We only need the time if it changed signs on your birthday, and we tell you when that happened.
What if Mercury was retrograde when I was born?
About 19% of people are born with Mercury retrograde (we measured this from our 1950–2050 retrograde table). Astrologers associate it with a reflective, unconventional thinker who revisits ideas before speaking.
Astrology is a symbolic and cultural tradition. The planetary positions on this site are calculated with astronomical accuracy; the interpretations describe what astrologers associate with them and are not scientifically validated predictions about personality, relationships or the future.
