A person's zodiac sign is determined by their date of birth.
The zodiac signs are based on the position of the sun, moon, and planets at the time of a person's birth.
According to astrology, a person's zodiac sign can influence their personality traits and life path.
Some people believe that a person's zodiac sign can change over time due to shifts in the position of the stars and planets.
However, most astrologers believe that a person's zodiac sign is fixed and cannot change.
Ultimately, whether or not a person's zodiac sign can change is a matter of debate among astrologers and enthusiasts.
