How the Mercury sign relates to your Sun sign
Mercury usually stays in a sign for about 2 to 3 weeks; around its retrogrades (about three a year) it can stay in one sign for around two months. Mercury is never more than about 28° from the Sun, so your Mercury sign is your Sun sign or the sign on either side.
Each sign page lists every period Mercury spent in that sign from 1940 to 2030, with ingress times. If your birth date falls inside a period, that is your Mercury sign. If you were born on a changeover day, enter your birth time in the calculator above.

FAQ
- How do I find my Mercury sign?
- You only need your birth date. The free calculator on this page finds which sign Mercury was in on that day. If Mercury changed sign on your birthday, add your birth time to settle it. Each sign page also lists Mercury's dates from 1940 to 2030.
- What does the Mercury sign mean?
- In Western astrology the Mercury sign describes thinking, speaking, learning and handling information. It is read as a separate layer from the Sun sign (will and direction) and the Moon sign (feelings).
- Can my Mercury sign differ from my Sun sign?
- Mercury usually stays in a sign for about 2 to 3 weeks; around its retrogrades (about three a year) it can stay in one sign for around two months. Mercury is never more than about 28° from the Sun, so your Mercury sign is your Sun sign or the sign on either side.
- Do I need my birth time?
- Usually not. Only when Mercury changes sign during your birthday does the calculator show both signs.
