Questions people ask
What is my Mercury sign?
The sign Mercury was in at your birth. Mercury is never more than 28° from the Sun, so it’s always in your Sun sign or one of the two signs either side.
What does Mercury rule in astrology?
Thinking, speaking, writing, learning style, curiosity, short trips and everyday problem-solving.
Do I need a birth time for my Mercury sign?
Mercury can move up to 2° a day, so on change-over days the time decides it. The calculator flags those cases; otherwise the date is enough.
Where is Mercury strongest?
Mercury rules Gemini and Virgo and is exalted in Virgo. It is in detriment in Sagittarius and Pisces and in fall in Pisces, where thinking runs on intuition rather than logic.
Was I born during Mercury retrograde?
Around one in five people were. The calculator marks it “retrograde”. Astrologers read a retrograde Mercury as a reflective, non-linear thinker who processes before speaking. See our Mercury retrograde page for current dates.
