Planetary hours
in Karaj.
The day, from sunrise to sunset, is cut into twelve equal hours; so is the night, from sunset to the next sunrise. Each hour carries a planet, in the Chaldean order. A planetary hour therefore lasts 60 minutes only at the equinoxes: it all depends on the date and the city. Here are the exact hours for your city; what you do with them is up to you.
