What is a natal chart?
A natal chart (or birth chart) maps where the Sun, Moon, and planets sat across the twelve zodiac signs and twelve houses at the exact moment and place of your birth. It is the foundational chart western astrology uses to interpret an individual's character.
What if I'm not sure of my birth time?
The rising sign and houses are very sensitive to birth time. If you're unsure, you can start with an estimate of 12:00 — most of the ten planets' signs will still be correct, but treat the rising sign and houses as approximate. We recommend confirming the exact time with family or your birth certificate, then recalculating.
How accurate is it?
This tool uses widely adopted astronomical algorithms to compute planet positions and the Placidus house system for the houses (automatically switching to the equal house system at high latitudes). The sign and house each planet falls into match those from authoritative astrology software. If you were born during daylight saving time, we recommend using manual mode and adjusting the time zone offset yourself.
