A birth chart is a snapshot of the sky at the exact moment, date, and place of your birth. It plots the positions of the sun, moon, and planets across the twelve zodiac signs and twelve houses, revealing your core personality, emotional patterns, communication style, relationship needs, and life themes.

Yes. Generating your birth chart and reading the full nine-section AI-powered analysis is completely free with a Celestio account. We do not charge for birth chart readings — you only pay for compatibility and transit reports if you choose to add them.

For the most accurate reading, especially for the rising sign and house placements, the exact birth time (to the minute) is ideal. If you only know the approximate time, the sun, moon, and planet placements will still be accurate, but the rising sign and house positions may shift. You can update your birth time later if you find it on your birth certificate.

You can still generate a birth chart without a birth time — Celestio will use a noon-based chart that omits the rising sign and house placements but still gives you a meaningful read on your sun, moon, and planets. The reading flags which sections are time-dependent so you know what to revisit if you find your birth time later.

Birth charts are generated in about 20 to 25 seconds. Astronomical positions are calculated immediately, then our AI writes the personalized nine-section reading in parallel — the page updates as each section completes.
