What is a Birth Chart?

A birth chart (natal chart) is a snapshot of the sky at the exact moment and location of your birth. It maps the positions of planets, the Sun, Moon, and other celestial bodies across the 12 astrological houses.

Your birth chart serves as a cosmic blueprint, revealing insights about your personality, strengths, challenges, and life path.

The "Big Three": Sun, Moon, and Rising

While most people know their Sun sign, your Moon sign and Rising sign (Ascendant) are equally vital. Your Sun represents your core essence and ego, your Moon governs your emotional inner world, and your Rising sign dictates how you present yourself to the world. Together, they form the "Big Three" pillars of your astrological identity.

Planetary Aspects: The Cosmic Conversation

The geometric angles between planets, known as aspects, reveal the dynamic conversations happening within your psyche. A trine suggests natural flow and talent, while a square indicates tension that fuels growth and ambition. Understanding these relationships is key to unlocking your full potential.
