Understanding Your Sun Sign

In astrology, your Sun Sign (also known as your Star Sign) represents your core essence, your personality, and the central focus of your life. It is determined by the position of the Sun at the exact moment of your birth. While your full birth chart includes many other planets, the Sun sign is the most widely recognized component of modern Western astrology.

How the Sun Sign Calculator Works

The Sun travels through the twelve signs of the zodiac over the course of a year, staying in each sign for approximately 30 days. This calculator takes your month and day of birth and maps them against the tropical zodiac dates. For example, if you were born on July 25, you fall into the Leo range, which typically begins on July 23.

Frequently Asked Questions

What if I was born on a "Cusp"?
Being born on the cusp means your birthday falls near the date where one sign ends and another begins. While this calculator uses standard date ranges, the exact time of the Sun's shift varies slightly each year. If you are on the very edge, you might feel qualities of both signs!

Is the Sun sign the same as my Horoscope?
A horoscope is a forecast based on your Sun sign. Your Sun sign is a permanent part of your identity based on your birth date, whereas horoscopes change daily, weekly, or monthly based on current planetary movements.
