The Rising Sign is your Self Image
The Sign rising over the horizon at the time of your birth is the Ascendant, or Rising Sign. This changes every two hours, approximately (see note below table). Even twins born as little as five minutes apart could have different ascendants, which would make a real difference in their horoscopes and so in their personalities. The formula for calculating your rising sign by hand is complex and needs several sets of tables, so we have installed a wizard that will accurately calculate it if you know your birth time, so giving you your correct ascendant (rising sign)—as well as a rule of thumb estimator (for the technologically challenged!) at the bottom of this page.
Hey, it's an instant Rising Sign Wizard! Excellent. It's an astrologer in a box, and is pretty accurate, though it does use the Swiss Ephemeris, so sometimes you might get a discrepancy of a few minutes in arc from our consultation charts (where we use the American Ephemeris, based on US Naval Observatory data). Now you can calculate your true rising sign on this page, with our handy new Rising Sign Wizard. To find your ascendant, or rising sign, just enter your birth date and time in the wizard, select your place of birth and click "Next". Then you will find out—with a brief rundown of what it means. Or, of course, you can still use our venerable rule of thumb estimator.

Or Estimate Your Rising Sign in the Table:
Remember, this is a rough estimation by rule of thumb, not a sophisticated calculator!
Can't figure out the free Rising Sign Wizard? To use this simple manual estimator, look along the row that matches your birth time until you come to the column matching your Sun Sign. The sign shown there is your Rising Sign, unless you were born in a very high latitude, or on a cusp, or at a time (say 2pm) when signs are changing. (Remember to check and allow for daylight saving, war time, or summer time when you were born).
