Frequently asked questions
What are planetary hours?
Planetary hours, also called kabbalistic hours, divide each day and night into segments that are each ruled by one of the seven classical planets — Saturn, Jupiter, Mars, the Sun, Venus, Mercury, and the Moon. The ruling planet gives each hour a distinct energy used to time actions.
How do I find the best planetary hour for something?
Decide what you want to do, match it to the planet that governs that kind of action (Mercury for messages, Jupiter for money, Venus for love), then act during that planet’s hour today. These guides map common actions to their strongest planetary hours.
Do I need to believe in astrology to use planetary hours?
No. You do not have to believe in anything to use planetary hours. Time a few actions to the favourable hours for a week and judge it by the results. The tradition treats it as something to test, not something to take on faith.

Yes. Every guide here is free to read. The Kabbalistic Cycles app is also free to start with no credit card, and it calculates your exact planetary hours automatically so you never have to work them out by hand.
