How it works
Find sunrise in the selected UTC day, the following sunset and next sunrise. Divide each interval into twelve parts and cycle Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon, beginning with the weekday ruler at local sunrise. Enter the correct local offset. Polar missing events are rejected; the labels do not establish auspicious or safe times.

Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
Astrology is a cultural and entertainment framework, not a scientifically validated way to predict personality, health, relationships or future events. Astronomical positions do not validate astrological interpretations.
