Quick Ascendant Calculator
Calculate Your Ascendant:
Try this quick and easy calculator to determine your Ascendant. An accurate birth time is required. Be sure to read our interpretations of your Ascendant here.
If you’d like a more comprehensive list of your Ascendant sign, planet signs, and houses without the interpretations, or if the atlas is busy (the Submit button sometimes doesn’t work when the atlas is too busy), then click here.
**Please note that the Ascendant is highly sensitive to a correct time zone. While the calculator above is excellent for time zones for births from 1970 onward, it’s missing some of the historical time changes. Daylight saving time, in particular, was not standardized and varied greatly not only between states but often between towns and cities. If you were born before 1970 or in very high latitudes (above 66.5 N), use our Free Report section and/or check your Ascendant with us at firstname.lastname@example.org to be certain.
While you can determine many astrological positions even with an unknown birth time, the Ascendant and house positions are highly sensitive to birth times.
See our Ascendant/Rising Sign Interpretations for detailed information about your Ascendant.
