Your birth chart

The sky as it stood the minute you arrived — your Sun, your Moon, your rising sign, and everything else that was turning. Free, and nothing is kept.

Local time of birth; choosing a city fills in the timezone.

Picking a city fills in the coordinates

Tick it and the tool sweeps the whole day at the birth place instead of casting a chart at a time nobody knows; the time typed above is then ignored.

Placidus is what most charts use. Whole sign and equal houses exist at every latitude; Placidus and Koch do not beyond the polar circles, and say so.

Fill in the date, the time and the place you were born, and the chart is drawn for that exact minute. The time matters more than it sounds: the rising sign changes about every two hours, so an hour's guess moves it entirely. If you don't know it, tick the box — the tool sweeps the whole day instead, and tells you what stays true either way.

Nothing you type is kept. Your birth details are never stored and never travel in a link, so there is nothing to share by accident.
