What is a Natal Chart (Birth Chart)?

A natal chart (or birth chart) is a cosmic snapshot of the sky at the exact moment and location you were born. It maps the positions of the Sun, Moon, planets, and astrological houses, representing your personality traits, potential path, and emotional blueprint.

What information is needed to calculate a birth chart?

To calculate an accurate birth chart, you need your exact birth date, exact birth time (hour and minute), and birth city. The exact time is critical to accurately place your Ascendant (Rising sign) and the house cusps.

Q: What is the difference between Placidus and Whole Sign house systems?

The Placidus system divides time between day and night, leading to houses of unequal sizes. The Whole Sign system makes each house exactly one zodiac sign (30 degrees each), starting with the sign of the Ascendant as the 1st House.

✦ Quick Summary: Reading Your Chart

Your birth chart maps the exact positions of the Sun, Moon, and planets at the minute you were born. It serves as a psychological blueprint for your core identity, emotional habits, and life path in Western astrology.

What do Sun, Moon, and Rising signs mean?

The three most influential elements in your natal chart are:

The Sun Sign: Your core identity, ego vitality, and central conscious path.
The Moon Sign: Your subconscious instincts, emotional sanctuary, and personal needs.
The Ascendant (Rising Sign): The zodiac sign crossing the eastern horizon at birth, shaping your persona, lens, and initial presentation.

What is the difference between Placidus and Whole Sign houses?

Your chart is divided into 12 sections called houses, each ruling a specific life vector (like career or romance). Placidus calculates these houses based on time, resulting in unequal quadrant sizes. Whole Sign aligns each house directly with each 30-degree zodiac sign.
