Sun Sign Calculator

Enter your birth date to find your exact Sun sign, worked out from the real position of the Sun. This is the accurate way to settle cusp birthdays, where the usual date charts can put you in the wrong sign.

Birth time is optional. If you leave it blank we use noon. Time only changes the answer when you are born within about a day of a cusp, right as the Sun crosses from one sign into the next.

How this works. Your Sun sign is calculated from real astronomy (the same engine used inside the Alya app), using the tropical zodiac. The Sun's position along the ecliptic is effectively the same everywhere on Earth, so no birth place is needed. Your details are used only in your browser to work out the sign, and nothing is sent anywhere.

For entertainment and reflection. Astrology is a symbolic tradition, not a science. This result is grounded in the real position of the Sun, but its meaning is interpretive and is not medical, psychological, legal or financial advice.
