Zodiac Sign Calculator

Your sun sign (or star sign) is determined by the position of the sun on your birthday. It's the most commonly known zodiac placement and represents your core identity and ego. A full astrological birth chart also includes your moon sign (emotions) and rising sign (outward personality).

A "cusp" refers to birthdays right at the transition between two signs (typically within a few days). Technically, you are one sign or the other based on the exact time and place of birth. The sun moves between signs at a specific hour each year — if you're on a cusp date, check the exact time of the sign change for your birth year.
