FAQ
Why are planetary hours different lengths?
Day and night are each divided into 12 equal parts based on sunrise and sunset. Since daylight and darkness vary throughout the year, planetary hours are rarely 60 minutes long.
Which day starts the week?
In traditional astrology, Sunday (ruled by the Sun) starts the week. The first hour after sunrise on Sunday is a Sun hour.
Do I have to use my exact location?
Yes. Planetary hours depend on local sunrise and sunset times, which vary by location. Using your city gives accurate results.
