💡 Why Birth Time Matters
Your exact birth time determines your Rising Sign (Ascendant) and house placements, which are crucial for an accurate birth chart reading. If unsure, use 12:00 PM.
What is a Birth Chart?
A birth chart (also called natal chart) is a snapshot of the sky at the exact moment you were born. It reveals the positions of the planets, Sun, and Moon in relation to the 12 zodiac signs and 12 houses of astrology.
Think of it as your unique cosmic blueprint - a map of your personality, life path, strengths, challenges, and potential. While your Sun sign represents your core identity, your complete birth chart shows the intricate details of your astrological makeup.

Birth Chart FAQs
What if I dont know my exact birth time?
If you dont know your exact birth time, use 12:00 PM (noon) as a default. While this wont give you an accurate Rising sign or house placements, youll still get correct planetary positions for your Sun, Moon, and other planets. For the most accurate chart, try to find your birth certificate.
How often should I check my birth chart?
Your birth chart remains the same throughout your life - its your cosmic blueprint. However, you can check transits (current planetary positions) to see how they interact with your natal chart. Many people review their chart during important life transitions or annually.
What is the difference between birth chart and horoscope?
Your birth chart is unique to you and doesnt change. Horoscopes are general predictions based on Sun signs. A birth chart gives you personalized insights, while horoscopes provide broad guidance for your Sun sign.
Why are some planets in the same sign for everyone?
Slow-moving planets like Uranus, Neptune, and Pluto stay in the same sign for several years, affecting entire generations. Faster-moving planets (Moon, Mercury, Venus, Mars) change signs frequently, creating more individual influences.
Can my birth chart predict my future?
Your birth chart doesnt predict a fixed future but reveals potentials, tendencies, and life themes. It shows your natural strengths, challenges, and the kinds of experiences you are likely to attract. Your free will always determines how these energies manifest.
