CALCULATE, THEN CHECK THE INPUT
Rising Sign Calculator
Your birth details
Your result
LOADING MODELAn Ascendant needs a moment and a place.
Enter a recorded birth time, UTC offset and coordinates to calculate the tropical Rising sign. The page will run a second check ten minutes later.
THE ANSWER, WITH ITS LIMIT
Your Rising sign is the zodiac sign on the eastern horizon at your recorded birth moment and location.
It is not established by a Sun sign, a birth date alone, or a chart made without a reliable birth time. This calculator computes the tropical Placidus Ascendant locally with Swiss Ephemeris, then reports the Ascendant sign and degree.
Three input states
- Can calculate
- Date, recorded time, UTC offset, latitude and longitude are present.
- Can record, not calculate
- Date and city label are present but the time or coordinates are missing.
- Needs checking
- A recorded time is supplied, but the second run lands in a different sign within ten minutes.
A RECEIPT YOU CAN RECHECK
Keep the settings beside the result.
Many chart wheels hide the inputs that determine an Ascendant. This page keeps the local time, UTC conversion, coordinate pair, tropical zodiac, Placidus horizon calculation, Julian day and exact longitude together in a copyable receipt.
The comparison is a sensitivity check, not a claim that every ten-minute change alters every chart. It shows whether the specific input you gave moves across a sign boundary within that interval.
What to do with the comparison
If both runs show the same sign, record that sign with the time used. If they differ, treat the sign as time-sensitive and check the birth record before interpreting it.
QUESTIONS BEFORE INTERPRETATION
Use the output carefully.
Can I find my Rising sign without a birth time?
No. This page does not substitute noon for an unknown time because the Ascendant and houses depend on the horizon at the birth moment.
Why does another Rising sign calculator disagree?
Compare the recorded time, historical UTC offset, coordinates, zodiac type and house method. Keep the calculation receipt so that each setting can be checked instead of comparing labels alone.
What is the difference between a Rising sign and a Sun sign?
Your Sun sign is based on the Sun’s zodiac longitude. A Rising sign is the Ascendant on the eastern horizon, so it needs time and location as well as date.
