What Is a Zodiac Sign?
A zodiac sign is based on the position of the sun on the day you were born. There are 12 zodiac signs in Western astrology, and each one covers a range of dates throughout the year. Your sign is linked to one of four elements — Fire, Earth, Air, or Water — which shapes the core traits tied to your personality. For example, Fire signs like Aries and Leo are known for boldness, while Water signs like Cancer and Pisces are known for deep emotion. Your sun sign is just one piece of the puzzle — for a fuller picture of your astrological profile, you can generate a complete birth chart that maps the positions of all the planets at the time of your birth.
Western Zodiac vs. Chinese Zodiac
The Western zodiac uses your birth month and day to find your sign. The Chinese zodiac works differently. It follows a 12-year cycle, and each year is tied to an animal like the Rat, Dragon, or Tiger. Your Chinese zodiac animal is based on the year you were born. Because Chinese New Year falls on a different date each year (usually between late January and mid-February), people born in January or early February may belong to the previous year's animal. You can use our date calculator to check whether your birthday fell before or after Chinese New Year in a given year.
What Is Zodiac Compatibility?
Zodiac compatibility looks at how well two signs get along. Signs that share the same element often connect easily. Signs with opposite elements may need more effort to understand each other. Compatibility scores can cover areas like emotions, communication, romance, and friendship. These scores are based on how the elements, modalities, and positions of the two signs interact with each other on the zodiac wheel.
What Is a Cusp Sign?
A cusp sign happens when your birthday falls within a day or two of a sign change. This means you may show traits from both signs. For example, someone born on November 21 sits near the Scorpio-Sagittarius boundary and could feel a mix of both signs. Traditional astrology assigns only one sun sign per date, but many people find cusp descriptions match them well. To dig deeper into how your birth date shapes other parts of your astrological identity, explore your moon sign for emotional insights or your rising sign for how others perceive you.
