planetary hours today
To get today's planetary hours, pick your city and read the table: it lists the 12 day hours and the 12 night hours, each with its ruling planet, start and end. The hour in effect is highlighted, with a countdown to its end.
Brasilia time, UTC-3; the astronomical day is 12 h 48 min long.
The first hour of the day belongs to Friday's ruler.
Close to the city's solar noon.
First hour of the night, 55 minutes and 55 seconds long.
Last hour, ending at Saturday's sunrise.
They are 24 divisions of the astrological day: 12 between sunrise and sunset and 12 between sunset and the next sunrise. Each hour is ruled by a classical planet (Saturn, Jupiter, Mars, Sun, Venus, Mercury or Moon), in a fixed sequence that starts with the planet of the weekday.
Yes. The times shift a little each day, because sunrise and sunset move by a few seconds or minutes, and the rulers change with the weekday. Only the order of the planets is fixed.
No. Just type the city name; the search covers cities with more than 15 thousand inhabitants worldwide. Location is an optional shortcut and, if you allow it, it never leaves the device.
It does. Times come out on the city's local clock, with daylight saving applied when it exists. The length of the hours does not change because of it, since it comes from the interval between sunrise and sunset.
