Enter your date of birth, exact birth time and birthplace to generate a complete natal chart — every planet by sign, degree and house, your Ascendant and Midheaven, the house cusps, and the aspects between them.
Positions come from the Swiss Ephemeris, the same ephemeris professional astrologers rely on, calculated for the exact moment and coordinates of your birth. Houses use the Placidus system and the chart is cast in the tropical zodiac. Your birthplace is resolved to latitude, longitude and the historical timezone offset in force on that date, so charts for births before a daylight-saving change are cast against the offset that actually applied.
Yes. Generating your chart is free. An email address is required so the chart can be sent to you.
Your date of birth, your birth time as precisely as you know it, and the city you were born in.
The chart still generates, but the Ascendant, Midheaven and house cusps move roughly one degree every four minutes, so without an accurate time those placements are approximate. Planetary signs remain reliable — only the Moon moves fast enough for the sign itself to be uncertain.
Placidus, the most widely used system in modern Western astrology.
Nothing — they are two names for the same thing: a map of the sky at the moment and place you were born.
