Why is exact birth time needed?

Without time you only get the Sun sign and an approximate Moon. The Ascendant changes every ~2 hours and the houses depend on time.

Is the natal chart free?

Yes. The base chart with Sun, Moon, Ascendant and planets is free. PRO adds aspects, transits and AI analysis.

Date of birth, exact time and city. That's enough for a full natal chart.

What your natal chart shows
