What is a Mercury sign?
Mercury at your birth
Your Mercury sign is the zodiac sign Mercury occupied at your birth. From Earth's viewpoint Mercury remains relatively close to the Sun, so only certain Sun–Mercury sign combinations are possible.
Why exact calculation matters
Mercury can change signs and can station retrograde or direct. An ephemeris-based calculation identifies its actual sign, degree, speed, and retrograde status rather than relying on a generic date table.
Communication in context
Mercury's sign is one layer. Its house shows where mental activity concentrates, while aspects to the Moon, Sun, Venus, Mars, Saturn, and other points describe how thinking connects with feeling and action.

Questions, answered
Mercury Sign Calculator FAQ
What does my Mercury sign mean?
It describes your preferred style of thinking, learning, processing information, making decisions, and communicating. It does not measure intelligence.
Can Mercury sign affect compatibility?
Mercury comparisons can illuminate communication rhythm and misunderstanding, but compatibility also depends on emotional needs, attraction, values, houses, and aspects between both complete charts.
Do I need a birth time to calculate Mercury?
A date often identifies Mercury's sign, but exact time resolves a sign-change day, gives a precise degree, and is required to calculate a reliable house placement.
What does Mercury retrograde at birth mean?
Natal Mercury retrograde is traditionally associated with a more internal, reflective, or nonlinear processing style. It does not predict poor communication or make someone less intelligent.
