Frequently Asked Questions
How is my zodiac sign determined?
Your Western zodiac sign (also called sun sign) is determined by the position of the Sun in the sky on the day you were born. This is defined by your birth month and day, not your birth year. The zodiac divides the year into 12 periods, each associated with a constellation.
What if I am born on the cusp between two signs?
A "cusp" birth occurs when your birthday falls in the first or last day or two of a zodiac sign. While some astrologers recognize cusps, the official definition uses specific dates. This calculator uses the standard dates. If you are a cusp birthday, you may feel a connection to both adjacent signs.
What is the difference between sun sign and rising sign?
Your sun sign (calculated here) is based on your birth date and represents your core personality. Your rising sign (ascendant) requires your exact birth time and location, and represents how you present yourself to the world. Many astrologers consider both when doing a full reading.
What is the rarest zodiac sign?
Aquarius (January 20 – February 18) and Capricorn (December 22 – January 19) are statistically the least common birth months in the US, making those signs slightly rarer. Scorpio and Virgo tend to be among the most common.
