Rising Sign Calculator
Calculate your Ascendant by sign and exact degree, then see the chart ruler that carries that rising sign through the rest of the natal chart.
Calculate your Rising sign
The Ascendant changes quickly. Exact local birth time and place are required for a responsible result.
Birth data
Choose a city from the suggestions for coordinates.
A small time difference can change the Ascendant degree and, near a sign boundary, the Rising sign itself.
What makes a Rising sign calculation precise
The Ascendant depends on date, exact local time, coordinates, time-zone history, and house geometry. That is why Regu does not offer an unknown-time Rising result.
Read the ruler after the sign
The Rising sign is the doorway, but the traditional chart ruler points to the planet carrying that doorway into a specific sign and house.
Common questions
Why is birth time required for the Rising sign?
The Ascendant moves through the zodiac roughly once per day and changes degree quickly, so date and place alone are not enough.
What is the chart ruler?
The chart ruler is the planet that traditionally rules the Rising sign. Its sign and house add the next layer of natal context.
