To create an individual natal chart, you need three specific pieces of information: the precise date, time, and location of your birth.1

A natal chart serves as a map of the heavens, illustrating the relative positions of the Sun, the Moon, the planets, and the ascendant and midheaven signs at the exact moment and place you were born. Because these celestial bodies are believed to exert an influence based on their geometric relationships at that specific time, this data is essential for an accurate calculation.1

While general horoscopes found in media often require only a birth date to forecast for an entire zodiac sign, an individual natal chart provides a more personalized analysis of character, psychological patterns, and life paths. By using the exact birth details, astrologers can plot these positions to interpret your unique blueprint.21
