A "Sun sign" refers to the zodiac sign that corresponds to the position of the Sun at the time of a person's birth. In astrology, there are twelve Sun signs, each associated with specific personality traits and characteristics. These signs are part of the Western astrology system and are commonly used in horoscopes. People often identify with their Sun sign, believing it influences their behavior and life experiences. The twelve signs include Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Each sign spans approximately one month, and many people check their daily horoscopes based on their Sun sign.
