Planetary Hours

This astrology application calculates unequal hours (through daily/nightly time intervals) from sunrise/sunset and helps you keep track of the ruling planetary (star) hour. It is meant for making the best use of time and also understanding the self, environment, and relations in real-time as well as in general. The planetary hours and Planetaro days calculator is based on the ancient Star of the Magi principle. The main rule is quite simple: the planet that rules the day and the hour promotes those activities which are in tune with its principle and can impede those activities which are of the opposite nature. Planetaro displays the astrologic hours for the current day. Also, the user can see the list of the hours for the chosen date.
