What you'll need
Date of birth
Exact time of birth — this fixes your rising sign and houses, so it's the detail that matters most. If you don't know it, you'll still get your planetary signs.
Place of birth — the city is enough.
What you'll get
Your birth chart is computed from Swiss Ephemeris data, so the positions are exact. You'll see your big three (sun, moon, rising), your planets each in a sign and house, your twelve houses, and your aspects.

Frequently asked questions
How accurate is this birth chart calculator?
The chart is computed from Swiss Ephemeris astronomical data — the professional standard — so the planetary positions match what an astrologer's software or an observatory would produce, to the arc-minute. The astronomy is exact; interpretation of the placements is a separate, reflective matter.
What do I need to calculate my birth chart?
Your date of birth, your exact time of birth, and your place of birth. The time is what fixes your rising sign and houses, so it matters most. Without it you can still see your planetary signs, but not your rising sign or house placements.
Is the birth chart calculator free?
Yes — enter your details and your chart is generated instantly, at no cost and with no account required.
Once you have your chart, The Oracle can read it with you — explaining what your placements mean for you and remembering the conversation as it grows. Your chart, computed properly and read as reflection.
