A map of one moment
A natal chart maps the apparent positions of the Sun, Moon, and planets at the time and place of birth. Astrology interprets the angular pattern symbolically; it is a reflective practice, not a scientific diagnosis.

What this tells you—and what it doesn’t.
More than a Sun sign
The Sun describes one central identity theme. The Moon, Rising sign, Mercury, Venus, Mars, houses, and aspects add emotional pace, social style, communication, relating, action, and tension.
Accuracy has rules
An exact birth time supports the Ascendant and houses. If your time is unknown, Astrology.ac omits those layers and marks any planet that changed signs that day instead of quietly inventing noon.
CLEAR ANSWERS
Before you calculate.
What information do I need?
Your birth date, the most accurate birth time you have, and birthplace. If the time is unknown, use the dedicated unknown-time option.
Which zodiac and house system are used?
The launch calculator uses the tropical zodiac and Whole Sign houses. Both settings are shown on every result.
Are my birth details saved?
Not in the anonymous flow. The server calculates the chart and returns placements; it does not write the raw inputs to a database.
