In my previous articles on how to cast spells, I discussed magical timing as determined by moon phases and by moon signs. Not every Witch worries about magical timing, but many feel that it gives a boost of energy that is conducive to your efforts.

Another way to plan your magical timing is by planetary hours. Planetary hours are useful if the ideal moon phase or moon sign is not possible when you want to cast your spell. They will lend you even more energy to your moon phase and moon sign timing.

Calculating planetary hours requires a bit of math, but if you can tell time and divide, you will be fine. It looks more complex than it actually is, so let’s get started.

1. How to Cast Spells Based on Planetary Influence

Planetary hours are the hours in the day associated with the various planets that have astrological influence: Saturn, Jupiter, Mars, Sun, Venus, Mercury, the Moon, and then the pattern is repeated. This sequence is known as the Chaldean order.

The Chaldean order is an ancient philosophy that is based on the planets' distance and velocity relative to their centers of orbit from a heliocentric perspective, as well as their astrological spheres from a geocentric perspective.

Each hour is ruled by a planet, and thus the planet's influences briefly come into play. Each day is kicked off by a different planetary influence. The difference that seems to confuse everyone is that planetary hours do not match the 60-minute hours of man-made time. They depend on the exact moments of sunrise and sunset.

2. Example of How to Cast Spells with Planetary Hours

Let’s say I want to cast a spell to help me with a career goal. Ideally, for my goal, the moon would be in Capricorn, but the moon doesn't enter Capricorn until near the end of the month. Worse, Mercury is in retrograde from now until February 28th, and that won't do at all! I just can't wait, so I decide to use the planetary hours of Saturn to draw the influences from it that I need, and I choose to do the spell on February 13th because the moon phase is good and I'm off that night.

So let's walk through the process of how to cast spells for the best outcome with planetary hours. I promise, try it a couple of times and you'll find it's not as complicated as you think!

When casting spells, don't go by conventional 60-minute hours; they'll fail you.

3. How to Calculate Daylight Planetary Hours to Cast Spells

The bolded text below are instructions for how to calculate planetary hours. The non-bolded text is how I would calculate using the specific February 13th example above.

1. Find the exact moments of sunrise and sunset.

You can find that in your local newspaper, or by going to sunrise and sunset websites. For my example, I looked up the time of the sunrise in my local paper. On February 13th, the sun is rising at 7:10 A.M. and setting at 6:20 P.M.

2. Calculate the number of minutes between sunrise and sunset.

From 7:10 A.M. to 7:59 A.M. there are 49 minutes until the start of sunrise until the complete sunrise. From 8 A.M. to 6 P.M. is 10 hours until the start of sunset. Multiplied by 60 minutes (10 hours X 60 minutes = 600 minutes). From 6:01 through 6:19 gives me 18 minutes until complete sunset. If I add 49 minutes + 600 minutes + 18 minutes = 668 minutes of daylight hours.

3. Divide the number of daylight minutes by 12.

There are 668 minutes between sunrise and sunset on February 13th, so we would calculate 668/12 = 55.58. In our example, we’ll only use the even minutes. Each planetary hour will be about 55 minutes long.

4. Figure out the times your daylight planetary hours begin and end.

in our example, since the sun is rising at 7:10 A.M. we'll start there and keep adding 55 minutes. The calculation for February 13th's daylight hours are in the table below.

4. Casting Spells Using Nighttime Planetary Hours

Now, I'm only half-way through calculating a 24-hour period. I've calculated the first 12 daylight planetary hours, now I want to calculate the 12 nighttime planetary hours. The process is roughly the same, but the length of each hour will almost always be different. Remember, for half the years, days are longer and nights are shorter; for the other half of the year, that reverses.

1. Find the time of sunset and the time of the next day's sunrise.

Using our example, the sun is set hour is 6:20 pm; the sun rise the next morning is 7:09 am (a minute earlier than the day before).

2. Calculate the minutes between sunset and sunrise.

6:21 pm to 6:59 pm = 38 minutes. There are 12 hours between 7 am and 7 pm, so 12*60= 720 minutes. 7:01 am to 7:09 am = 8 minutes. I add up all the minutes: 38 + 720 + 8 = 766 minutes between sunset and next day sunrise.

3. Divide the minutes between sunset and next day sunrise by 12 to find the length of nighttime planetary hours.

766/12 = 63.91. So that's 63 minutes long for each nighttime planetary hour on Feb. 13th.

4. Complete the chart, picking it up where you left off.

In my example, I would be adding 63 minutes for each planetary hour, and the remainder of my chart to cast spells by planetary hours would look like this:

5. Using the Chaldean Order in Sequence

Now you know (roughly) what time each planetary hour begins and what time it ends for a full 24-hour period. Now you’re going to apply the Chaldeon order of planets to it. This will depend on the day of the week.

Each day of the week, the first planetary hour begins with a different planet. You can see examples of this in the table below.

6. So How Does It All Fit Together?

1. Figure out the ruling planet of the day.

In my case, the ruling planet on February 13th would be Jupiter, since the day falls on a Thursday.

2. Make the ruling planet of the day your first planetary hour for that day.

My first planetary hour is from 7:10 to 8:05 A.M. for Thursday, Feb. 13th; therefore, my first planetary hour would be ruled by Jupiter.

3. Continue listing the rest of the planets in the Chaldean sequence. Repeat the sequence for the rest of the day's hours.

The Chaldean sequence was mentioned earlier: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and the Moon. Since my first planetary hour is Jupiter, I'll start with that, so my second planetary hour would be Mars, then the Sun, and so on.

Below, you'll find my final calculation for casting spells on February 13th.

When You Are Casting Spells...

Bingo! I Have My Timing to Cast Spells

I found that my planetary hours will be influenced by Saturn. Now I know how to cast spells successfully at 12:46 P.M. to 1:41 P.M., 7:24 P.M. to 8:27 P.M., or 2:54 A.M. to 3:58 A.M., despite the fact that other times would be working against me.

Sound confusing? Yes, it can seem that way, if you're looking at it all at once. But if you break down the steps, take them as one task at a time, you will find it's not all that difficult—just a bit tedious.

Still, once you get the hang of how to cast spells with planetary hours, it'll only take you a few minutes to figure out your timing. I'm fairly mathematically challenged (I was an English Lit major—'nuff said!), and it scared the heck out of me the first time I saw instructions on how to do this. After a few tries, I could do it in 10 minutes.

To practice, actually try to calculate any day at random. By doing it just once, a lot of the confusion falls away and you understand the process better.

When it comes to casting spells, my magical motto is, "every little bit helps!" Any little boost I can use to affect my spell, I'm going to take it. If you're already working with magical timing when spell casting, give planetary hours a try.

It's explained above in #3: find sunrise-sunset times for days or sunset-sunrise for night; calculate exact # of minutes between them; divide by 12; use the Chaldean Order to label.

Willow on March 13, 2020:

How'd you find out what the times would be? Is it mulitiples of seven?

Mackenzie Sage Wright (author) on March 07, 2020:

Sorry, I haven't been active here or on social media for a while as I spend the last year as caretaker for a parent in home hospice care.

I would let the spell play out and see what happens. Some people, like I said, don't even bother with magical timing. It can give work a boost or work against us a little, but it doesn't make or break the spell overall. Mars does offer some lustful energies, so it could be a help combined with your overall intent.

Only time will tell, though, so I would say see how things play out and then, if Mars brought something into a relationship you didn't want, try another spell to course-correct.

Bright blessings.

Hello, I recently discovered your writings. I sent you a msg on Facebook, but it doesn't appear you saw it. Anyway, I read your article on calculating planetary hours. This is the BEST and most helpful article on the topic that I have found on the web. I've been a Witch for a long time, but calculating the hours has always vexed me until now (figuring the length of time between hours accurately was a challenge).

So I recently did a love jar spell. And I wanted to bless the oils I had blended for the working. I started on a Sunday because I missed the opportunity to do it on a Fri. So I thought I'd start at the Venus hour. (I mistakenly thought that just as the first hour of the the day is ruled by the Sun, so too would the first hour of the night be ruled by the Sun.) But when I thought I had started on the Venus hour, I had actually started on the Mars hour. I suppose that would lend the spell energy and passion. But could you please recommend something I could do to remedy this--besides throwing out my oil and buying new oils or dismantling my jar, which I don't want to do, because everything else about it is fine? Thanks for your time.

P.I.I. on January 15, 2020:

Just one correction: The day is more important than the hour. If you want to work with Saturn's energy, you must do it on Saturday. The hour is secondary. In your example, by casting your spell on a Thursday during a saturnine hour, you would be working with Jupiter's energy with a little saturnine influence.

The planetary hours have been quite useful and observed by practicioners of horary astrology for centuries ! I am an event and mundane astrologer and the planetary hour helps with personal daily planning, as well as with post-mortem (explaining why events happened). In addition to manually calculating the hours, any astrology program like Solar Fire, Winstar, Kepler. etc. can give you the planetary hour for any given day. Thanks for sharing !

There is now an APP called Hours on the iPhone App Store (I am not sure if it’s on any other app stores). It does all the calculations for you, as well as provide Angel representations, herb corespondences, Incase, body, and key ideas.

I never read anything about that Planetary Hours before so this was definitely new to me. I follow the moon phases. I do a lot of my work with candles & crystals. I can’t wait to read anything about the retrograde that we’re in until September.

Hi there; Saturn doesn't do the spells for me, I just borrow a little of that energy. Saturn energy is very conducive to long-term learning and efforts that are a learning experience, ime. Thank you so much!

Roach Rabbit on October 16, 2017:

I don't understand how you got saturn to do your spells. How did it influence you're hours? Really great article, however. I love reading your posts.

MHermes, lol, I actually find it easier to calculate myself. Smart phones and apps confuse the hell out of me... I am SO not techno-literate.

Thanks KarthikKash! I appreciate your comment; thanks for stopping by, it's always good to hear from you :-)

KarthikKash on February 09, 2014:

very nice hub, indeed :) I extensively make use of planetary hours irrespective of the moon phase. It definitely adds extra boost. As you said, any additional boost for the spell is welcome.
