Natal chart online
The sky at the exact minute you drew your first breath. It is yours alone: even someone born the same day has another sky, another minute, another city. I calculate it free.
What the natal chart shows
The natal chart is the blueprint of the sky at the moment of birth. The planets spread across the twelve signs of the zodiac and the twelve houses, and the angles between them form the aspects.
The ascendant
The sign that was rising over the eastern horizon the minute you were born. It changes every two hours or so, which is why the exact time is needed: an hour off carries it into the next sign.
The houses
Twelve sectors of the chart, each an area of life. By default I divide by Placidus, the most used. You can choose whole signs or equal houses. Beyond the polar circle Placidus does not apply, and there I switch honestly to whole signs instead of drawing the impossible.
The aspects
The angles between planets: conjunction, sextile, square, trine, opposition. They show how the parts of the chart speak to one another.
How I calculate your chart
The sky does not ask what you believe. In the minute you drew your first breath, the planets stood where they stood, accurate to a degree. That is what I take: exactly as it was, no rounding, no guesswork.
The birth time I set to how the clocks actually ran that year and in that city. The hands have been moved more than once, and by now no one remembers. That is why under each calculation I note which time zone I used.
Frequently asked
What if I do not know the exact birth time?
Leave 12:00. The planets in the signs barely change, but the ascendant, the MC and the houses will be approximate: they depend on the time directly.
What house systems are there?
Placidus (the default, most common), whole signs and equal houses. If you were born beyond the polar circle, Placidus does not apply and the chart is built by whole signs.
Is the calculation paid?
No, the chart is built free and without sign-up.
You have the blueprint of the sky in front of you. What it says about your life is read sign by sign.
