Planetary Hours

Planetary hours have been in use for thousands of years. The idea of planetary hours may go back as far as 4000 years ago.

Each day has an astrological ruler.
Sunday is ruled by the Sun.
Monday is ruled by the Moon.
Tuesday is ruled by Mars.
Wednesday is ruled by Mercury.
Thursday is ruled by Jupiter.
Friday is ruled by Venus.
Saturday is ruled by Saturn.

Each hour of the day has an astrological ruler, as well. Our 24 'clock' hours are divided in two. One half is daylight and the other half is night. So, because we have varying daylight hours, the planetary hours may be shorter or longer than our clock hours.

The first planetary hour of the day belongs to that day's ruler and they follow in what is called the Chaldean order, from the slowest moving, towards the fastest moving, as they appear in the sky. So, we have Saturn, Jupiter, Mars, The Sun, Venus, Mercury, and The Moon.

So, if it is Wednesday, the first hour belongs to Mercury, the second to the Moon(the fastest), the third to Saturn(slowest), and so on.

Below, is a table of the planetary hours. Don't let the colors throw you. They are just to show the individual groupings of the 7 planets.

Using The Planetary Hours In Magic

In magic, the planetary hours are used to add energy to any magical working, to create more alignment. If you are doing a spell for love, you would want to do it in the hour of Venus. The Key Of Solomon contains a lot of information about planetary hours and how to use them. To learn more about what magical workings are done at what planetary hour, click the button.

From The Key Of Solomon:

In the Days and Hours of Saturn thou canst perform experiments to summon the Souls from Hades, but only of those who have died a natural death. Similarly on these days and hours thou canst operate to bring either good or bad fortune to buildings; to have familiar Spirits attend thee in sleep; to cause good or ill success to business, possessions, goods, seeds, fruits, and similar things, in order to acquire learning; to bring destruction and to give death, and to sow hatred and discord.

The Days and Hours of Jupiter are proper for obtaining honours, acquiring riches; contracting friendships, preserving health; and arriving at all that thou canst desire.

In the Days and Hours of Mars thou canst make experiments regarding War; to arrive at military honour; to acquire courage; to overthrow enemies; and further to cause ruin, slaughter, cruelty, discord; to wound and to give death.

The Days and Hours of the Sun are very good for perfecting experiments regarding temporal wealth, hope, gain, fortune, divination, the favour of princes, to dissolve hostile feeling, and to make friends.

The Days and Hours of Venus are good for forming friendships; for kindness and love; for joyous and pleasant undertakings, and for travelling.

The Days and Hours of Mercury are good to operate for eloquence and intelligence; promptitude in business; science and divination; wonders; apparitions; and answers regarding the future. Thou canst also operate under this Planet for thefts; writings; deceit; and merchandise.

The Days and Hours of the Moon are good for embassies; voyages envoys; messages; navigation; reconciliation; love; and the acquisition of merchandise by water. 1

Thou shouldest take care punctually to observe all the instructions contained in this chapter, if thou desirest to succeed, seeing that the truth of Magical Science dependeth thereon.

The Hours of Saturn, of Mars, and of the Moon are alike good for communicating and speaking with Spirits; as those of Mercury are for recovering thefts by the means of Spirits.

The Hours of Mars serve for summoning Souls from Hades, 2 especially of those slain in battle.

The Hours of the Sun, of Jupiter, and of Venus, are adapted for preparing any operations whatsoever of love, of kindness, and of invisibility, as is hereafter more fully shown, to which must be added other things of a similar nature which are contained in our work.

The Hours of Saturn and Mars and also the days on which the Moon is conjunct 1 with them, or when she receives their opposition or quartile aspect, are excellent for making experiments of hatred, enmity, quarrel, and discord; and other operations of the same kind which are given later on in this work.

The Hours of Mercury are good for undertaking experiments relating to games, raillery, jests, sports, and the like.

The Hours of the Sun, of Jupiter, and of Venus, particularly on the days which they rule, are good for all extraordinary, uncommon, and unknown operations.

The Hours of the Moon are proper for making trial of experiments relating to recovery of stolen property, for obtaining nocturnal visions, for summoning Spirits in sleep, and for preparing anything relating to Water.

The Hours of Venus are furthermore useful for lots, poisons, all things of the nature of Venus, for preparing powders provocative of madness and the like things.

But in order to thoroughly effect the operations of this Art, thou shouldest perform them not only on the Hours but on the Days of the Planets as well, because then the experiment will always succeed better, provided thou observest the rules laid down later on, for if thou omittest one single condition thou wilt never arrive at the accomplishment of the Art.

For those matters then which appertain unto the Moon, such as the Invocation of Spirits, the Works of Necromancy, and the recovery of stolen property, it is necessary that the Moon should be in a Terrestrial Sign, viz.:--Taurus, Virgo, or Capricorn.

For love, grace, and invisibility, the Moon should be in a Fiery Sign, viz.:--Aries, Leo, or Sagittarius.

For hatred, discord, and destruction, the Moon should be in a Watery Sign, viz.:--Cancer, Scorpio, or Pisces.

For experiments of a peculiar nature, which cannot be classed under any certain head, the Moon should be in an Airy Sign, viz.:--Gemini, Libra, or Aquarius.

But if these things seem unto thee difficult to accomplish, it will suffice thee merely to notice the Moon after her combustion, or conjunction with the Sun, especially just when she 2 quits his beams and appeareth visible. For then it is good to make all experiments for the construction and operation of any matter. That is why the time from the New unto the Full Moon is proper for performing any of the experiments of which

we have spoken above. But in her decrease or wane it is good for War, Disturbance, and Discord. Likewise the period when she is almost deprived of light, is proper for experiments of invisibility, and of Death.

But observe inviolably that thou commence nothing while the Moon is in conjunction with the Sun, seeing that this is extremely unfortunate, and that thou wilt then be able to effect nothing; but the Moon quitting his beams and increasing in Light, thou canst perform all that thou desirest, observing nevertheless the directions in this Chapter.

Furthermore, if thou wishest to converse with Spirits it should be especially on the day of Mercury and in his hour, and let the Moon be in an Airy Sign, 1 as well as the Sun.

Retire 2 thou then unto a secret place, where no one may be able to see thee or to hinder thee, before the completion of the experiment, whether thou shouldest wish to work by day or by night. But if thou shouldest wish to work by night, perfect thy work on the succeeding night; if by day, seeing that the day beginneth with the rising of the Sun (perfect thy work on) the succeeding day. But the Hour of Inception is the Hour of Mercury.

Verily, since no experiments for converse with Spirits can be done without a Circle being prepared, whatsoever experiments therefore thou wishest to undertake for conversing with Spirits, therein thou must learn to construct a certain particular Circle; that being done surround that Circle with a Circle of Art for better caution and efficacy.

Planetary Hours Calculator

To use the planetary hours calculator, you need to know the following: The longitude and latitude of the city where you reside (or the nearest larger city), and also the time zone, including daylight savings time, if applicable.

How To Get Your Coordinates +

You can get the longitude and latitude information easily from this Time-zone Atlas at All you need to do is select the part of the world you want to search and enter the city. Their system will look for all possibilities and you just find the one you want. Then, write down the coordinates and come back here and enter them into the form. It shouldn't take more than a minute or two.

For instance, I want to find the coordinates for Ordway, Colorado, where I live now.
Search: USA
Birth Town: Ordway
Ordway, CA (US): 34n00, 117w10, California
Ordway, CO (US): 38n13, 103w45, Colorado
Ordway, GA (US): 32n29, 84w57, Georgia (US)
Ordway, MA (US): 42n24, 71w35, Massachusetts
Ordway, SD (US): 45n35, 98w25, South Dakota

Well, I know it is the Colorado entry, so my coordinates are 38n13 and 103w45.
I enter the coordinates in the form below. I already know that my time zone is Mountain Daylight(MDT), so I select that in the form below. EzPz.

If you are not sure of your time zone, you can go to enter your city and a pin will show up on the map. My city, Ordway, Colorado, does not show up. The nearest city it shows is Colorado Springs, which is in the same time zone, so it's perfect. -6 hours MDT. This also took less than a minute.

Once you have this longitude and latitude information, you might want to store it somewhere on your computer. The time zone, you might want to verify every time, because, unless you live in Arizona, or outside the USA where there is not a time change, the time zone will change every 6 months.

The reason it is so important to have accurate information is because the hours are calculated based on sunrise and sunset times for your location. It's ok, if the longitude and latitude is for a town, less than 200 miles away. It will still be pretty close.
