Rising sign calculator
Free. No sign-up. We never receive your details.
Your rising sign (your Ascendant) changes about every two hours, so it needs your birth time and place. We show yours, warn you when it’s close to changing, and list every rising sign through your birth day.

What is a rising sign?
Your rising sign, or Ascendant, is the sign that was coming up on the eastern horizon when you were born. It colours the way you meet the world and the first impression you make.
The sky turns once a day, so the rising sign changes about every two hours, faster for some signs than others. That is why it needs your birth time and place, and why a rounded time can matter.
How we calculate it
The planets come from Astronomy Engine, an open-source library we checked against NASA’s JPL Horizons: within 11 arcseconds for our four test births. The Ascendant, MC and houses use our own code and match the leading chart sites to the minute.
Your local birth time is turned into world time with the time-zone rules of your birth place on that date, summer time included. The place card shows the offset used, and you can change it. Houses are Placidus unless you pick Whole Sign. The North Node is the mean node.
