How is a zodiac determined?

A zodiac is determined by the position of the Sun relative to the twelve constellations along the ecliptic, the apparent path the Sun takes across the sky throughout the year. Each zodiac sign corresponds to a specific time frame, typically one month, during which the Sun is in that particular constellation. The traditional Western zodiac is based on this astronomical positioning, aligning with the seasons, while the Chinese zodiac is based on a 12-year cycle, with each year associated with a specific animal. Both systems are used in Astrology to interpret personality traits and predict future events.
