Your birth chart
A birth chart is the photograph of the sky at the exact moment you arrived: where each planet stood, what was climbing over the horizon and how they were speaking to one another. Put in your date, your time and your city and the whole thing comes out, wheel and all.
If your town is not on the list, pick the nearest large city: a few kilometres will not move the result. One hour of error changes the rising sign nearly half the time, so the birth certificate is worth a look.
The chart is worked out with the same astronomical formulas the ephemerides use (positions checked against the real sign changes between 1998 and 2025). The reading, on the other hand, is symbolic: a portrait to recognise yourself in, not a diagnosis and not a prediction.
Your star sign is simply where the Sun happened to be on the day you were born, and that is about a tenth of the story. That morning, or that small hour, there was also a Moon sitting in some sign, an exact degree of the zodiac climbing over the horizon, and eight more bodies scattered across the sky, one or two of them apparently walking backwards. A birth chart is that whole photograph: the entire sky, in your minute and seen from your city.
Here it is worked out for real. The positions come from the same astronomical formulas the ephemerides use, and they have been checked against twelve genuine sign changes spread between 1998 and 2025 — Saturn entering Pisces, Pluto entering Aquarius, Uranus into Gemini — to within a day or two. Your time is converted to Universal Time using the historical clock rules of the place, which is exactly where half the internet slips: Britain ran an hour ahead all winter long from 1968 to 1971, and an hour of error moves the rising sign by nearly a whole sign.
What comes out is the wheel drawn, a table with the ten bodies by sign, degree and house, the aspects they form with one another and a reading of every piece. If you do not know your time of birth you can still run it: there will be no rising sign and no houses, since both depend on the clock, but the planets by sign are yours all the same. And if you only want the essentials, your Sun, your Moon and your Rising sign live next door.
