Your rising sign
Find your rising sign
Enter your birth date, time and city: you get your rising sign right away. If your time is approximate, we tell you the minute it changes sign.
Calculated with NASA data, accurate to a thousandth of a degree.
How we calculate it
Your local time is converted to Universal Time (the world's reference time) using the historical time zone of your birthplace, daylight saving time included. Then we find the sign that was rising in the east. If your time is approximate, we redo the calculation across the whole window and find the exact minute of each sign change.

Frequently asked questions
How do I find my rising sign?
You need your birth date, time and place. The calculation finds the sign rising in the east at that minute, in that place.
What if I don't know my birth time?
No time, no rising sign: it changes about every two hours. With an approximate time, we tell you whether it changes sign within the window, and at what minute.
Why is my rising sign different on another site?
Most often a different time or place, or a badly converted time zone. Arcanes shows how your time was converted in the details of your chart.
