The planetary hours use the Chaldean order to divide time. Each planetary hour of the planetary day is ruled by a different planet. The planet that rules the first hour of the day is also the ruler of the whole day and gives the day its name. Thus the first hour of Sunday is ruled by the Sun, the first hour of Monday is ruled by the Moon and so on.

However, planetary hours are not the same as the sixty-minute hours that we use for normal time-keeping. The day is split into two periods, daytime and nighttime. Sunrise to sunset is considered daytime. Sunset to sunrise of the next day is nighttime. Then these two periods are each divided into twelve equal length hours, which are the planetary hours. The planetary hours of the day and the planetary hours of the night will be of different lengths except on the Equinoxes, when light and darkness are balanced.

Each planetary hour is associated with a planet. These can be used to fine-tune a magickal working. This is one step up from performing magick on the day ruled by the planet best suited for the goal. This will give you a specific hour to work the magick.

Find all the planetary hours: Luna / Moon, Mercury, Venus, Sol / Sun, Mars, Jupiter, and Saturn!

Comes in handy

Great app. Simple to use. Seems accurate and takes the guess work out of which planetary hour were operating in. Suggestions for improving this app: would like the option to mute the page-turning sound without having to put my phone on vibrate; it's annoying when flipping between pages within the app. Maybe also add the ability to permanently change the volume as a setting (similar to Google Maps where the audio can be set to low, med, & high). That way I don't have to lower the volume each time I want to use the app. Also: Would love to see this become a more complete application where we can see upcoming void of moon events and moon phases. And finally: Under the legend, it would be nice to see the correspondences of each planet in the legend; The names of each planet in the legend seem redundant or unnecessary since anyone using this app should know what each planetary symbol means. Anyways, it's a great app, it's simple and easy to use, but it has lots of room for improvement.

Only for today's date

I really like this simple to use app but, just a warning, it is only good for today's date. For that I give it 4 stars. Wouldn't it be nice to choose the date?! It is hard to plan future magical actions or future ceremony times otherwise!

But thanks for the great convenience!
