Understanding Your Western Birth Chart (Natal Chart)

Your birth chart (also known as a natal chart) is an astronomical snapshot of the sky at the exact moment and location of your birth. In Western astrology, the birth chart maps the locations of the Sun, Moon, and 8 planets across 12 zodiac signs and 12 astrological house sectors.

The Core Elements of a Birth Chart

• The Sun Sign: Your core identity, ego, life force, and conscious purpose.
• The Moon Sign: Your emotional inner landscape, instincts, and subconscious needs.
• The Rising Sign (Ascendant): The zodiac sign rising on the eastern horizon at your exact birth time. Represents your outward personality and first impression.
• The 12 Houses: Life arenas ranging from personal identity (1st House) to career (10th House) and relationships (7th House).
• Aspects: Angular geometric angles (Conjunctions, Trines, Squares, Oppositions, Sextiles) formed between planets.
