Birth Time
The rising sign changes throughout the day, so exact time is the most important input.

Calculate Your Rising Sign
Use an exact birth time whenever possible. Even a small time difference can change the ascendant near sign boundaries.
How it works
What the Calculator Uses
The tool estimates the ecliptic degree rising on the eastern horizon at the moment and place of birth. For best results, use the time shown on the birth record and the birthplace coordinates rather than a current residence.
Birthplace
Latitude and longitude help locate the local horizon used for the ascendant estimate.
UTC Offset
The offset converts local birth time to universal time for the sidereal-time calculation.

Quick answers
Rising Sign Calculator FAQ
Is this rising sign calculator free?
Yes. The calculator is free to use and runs entirely in your browser.
Can I calculate a rising sign without a birth time?
A reliable rising sign needs a birth time. Without one, the result can be wrong because the ascendant moves quickly.
Should I use my current location?
Use the birthplace, not the current location, unless both are the same.
