Frequently Asked Questions
Q: How are planetary hours calculated?
Planetary hours are calculated by dividing the time between sunrise and sunset (for daytime hours) and sunset and the next sunrise (for nighttime hours) into 12 equal parts. The length of these "hours" varies depending on the season and latitude.
Q: Why are the hours not exactly 60 minutes long?
Because the length of daylight and nighttime changes throughout the year, the duration of each planetary hour also changes. They are only close to 60 minutes near the equinoxes.
Q: Do I need to know my exact sunrise/sunset times?
No, this calculator handles that automatically based on the location and date you provide. It uses precise astronomical calculations.
Q: Which planets are used?
The system uses the seven traditional astrological planets: Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. Uranus, Neptune, and Pluto are not part of this traditional system.
Q: Is this scientifically proven?
Planetary hours are part of traditional astrology and are not based on modern scientific principles. They are used as a symbolic or spiritual timing system by those who follow these traditions.
Q: How accurate is the location detection?
If you allow location access, the calculator uses your browser's geolocation capabilities, which are generally quite accurate for determining sunrise/sunset times. You can also manually enter any location worldwide.
