Rising Sign (Ascendant) Calculator
An approximate mathematical calculation of the eastern-horizon ecliptic intersection using the birthplace and local birth time.
Important: your current location may not be your birthplace. We request permission first and never send coordinates to the server. Nearby cities are suggestions, not definitive geocoding.
Accuracy and limitations
The calculation uses your browser’s historical IANA timezone data and a geometric horizon approximation. Birth-time errors, incorrect cities, daylight-saving transitions and high latitudes can affect results. A representative city is only an approximation, and atmospheric refraction and specialist house-system conventions are excluded; this is not a professional natal chart.
Astrology is for entertainment and self-reflection. There is no scientific evidence that zodiac signs predict the future, personality or relationship success.
