How Zodiac Sign Dates Work
Your zodiac sign — also called your star sign or sun sign — is determined by where the sun was positioned along the ecliptic on the day you were born. Each of the 12 zodiac signs corresponds to roughly a month-long window. Because these windows are based on Earth's orbit rather than the calendar, sign dates can shift by a day depending on the year — if your birthday falls right on a boundary (a "cusp"), it's worth double-checking against an exact chart.
