Frequently Asked Questions
How accurate is this?
It uses a real ascendant formula (sidereal time and the obliquity of the ecliptic) but a simplified constant for the ecliptic's tilt, so results are usually correct but can be off near a sign boundary - use professional astrology software for a precise natal chart.
Why do I need to enter my birth time and location?
Unlike your sun sign, the rising sign changes roughly every two hours and depends on exactly where on Earth you were born, so both are required for a meaningful result.
