What is a Sun Sign?

A Sun Sign, also known as a star sign or zodiac sign, is the position of the Sun at the time of a person's birth. It is one of the most fundamental elements in astrology and is believed to influence a person's personality, behavior, and life path.

How to Determine Your Sun Sign

Your Sun Sign is determined by the position of the Sun in the zodiac on your birth date. The zodiac is divided into 12 equal parts, each corresponding to a constellation. The formula for determining your Sun Sign is based on the date ranges associated with each sign:

\[SunSign = f(BirthMonth, BirthDay)\]

Where:

• \(BirthMonth\) = the month of your birth (1-12)
• \(BirthDay\) = the day of the month you were born (1-31)
• \(f\) = a function that maps the birth date to the corresponding Sun Sign
