One of the first things many practitioners discover when studying traditional magic is that timing matters. Whether reading medieval grimoires, Renaissance books on natural magic, or modern texts on ceremonial magic and traditional witchcraft, the same principle appears repeatedly: the heavens influence the quality of time.
Planetary days and hours are among the oldest methods of selecting auspicious moments for magical work. Rather than viewing every hour of every day as spiritually identical, this system suggests that each period of time carries the symbolic influence of one of the seven classical planets. By choosing a time that aligns with the purpose of a working, the magician seeks to perform their ritual "with the current" rather than "against it."
Whether one believes the planets exert literal spiritual influences, archetypal psychological forces, or simply provide a meaningful symbolic framework, planetary timing offers an elegant way to bring rhythm, intention, and discipline into magical practice.
The Seven Classical Planets
Planetary magic is based on the seven visible celestial bodies known to the ancient world:
- Saturn
- Jupiter
- Mars
- Sun
- Venus
- Mercury
- Moon
These are called the classical planets because they were known long before the discovery of Uranus, Neptune, and Pluto. Each accumulated centuries of symbolic associations through astrology, mythology, medicine, and magic.
Unlike modern astronomy, magical traditions focus less on the planets as physical objects and more on the qualities they represent.
Why Timing Matters
Traditional magical philosophy often describes the universe as a web of correspondences. Everything has affinities—colours, metals, herbs, scents, numbers, directions, spirits, and times. The goal is to create harmony between these elements.
Imagine attempting three different workings:
- a blessing for financial prosperity
- a ritual for healing
- a spell intended to sever unhealthy attachments
Although each may involve candles, prayers, or offerings, they are not considered equally suited to every day. Instead, traditional practitioners would likely choose:
- Thursday (Jupiter) for prosperity
- Sunday (Sun) for healing and vitality
- Saturday (Saturn) for endings or banishings
Planetary timing therefore becomes another correspondence—one that complements rather than replaces the other elements of ritual.
Understanding Planetary Days
Every weekday is ruled by one of the seven planets.
|
Day |
Planet |
Common Magical Themes |
|---|---|---|
|
Monday |
Moon |
Dreams, intuition, psychic work, emotions, fertility |
|
Tuesday |
Mars |
Courage, protection, conflict, strength, justice |
|
Wednesday |
Mercury |
Communication, study, travel, business, divination |
|
Thursday |
Jupiter |
Prosperity, success, wisdom, abundance, law |
|
Friday |
Venus |
Love, friendship, beauty, creativity, reconciliation |
|
Saturday |
Saturn |
Boundaries, ancestors, discipline, banishing, endings |
|
Sunday |
Sun |
Healing, confidence, leadership, blessing, vitality |
Choosing the appropriate day is often the simplest way to incorporate planetary timing into one's practice.
If you are blessing a new business, Thursday may be preferred.
If conducting ancestor work or releasing unhealthy habits, Saturday is traditionally favoured.
Many practitioners stop here, and there is nothing inherently incomplete about doing so. However, planetary hours allow for much finer timing.
What Are Planetary Hours?
Each day is divided into twenty-four planetary hours, but these are not fixed sixty-minute periods.
Instead:
- sunrise to sunset is divided into twelve equal hours
- sunset to the following sunrise is divided into another twelve equal hours
Because daylight changes throughout the year, planetary hours also change.
In summer:
- daytime planetary hours become longer
- nighttime planetary hours become shorter
In winter:
- daytime hours become shorter
- nighttime hours become longer
This reflects the ancient method of measuring time rather than our modern system of identical sixty-minute hours.
How Planetary Hours Are Assigned
Planetary hours follow the ancient Chaldean Order, based on the apparent speed of the planets:
Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon
The sequence repeats continuously.
The first planetary hour after sunrise is ruled by the planet governing that weekday.
For example, imagine sunrise occurs at 6:00 AM on Thursday.
Since Thursday belongs to Jupiter, the first several planetary hours would be:
|
Hour |
Planet |
|---|---|
|
First |
Jupiter |
|
Second |
Mars |
|
Third |
Sun |
|
Fourth |
Venus |
|
Fifth |
Mercury |
|
Sixth |
Moon |
|
Seventh |
Saturn |
|
Eighth |
Jupiter |
…and so on throughout the day and night.
By the following sunrise, the sequence naturally places the Sun at the beginning of the next day, producing Sunday after Saturday, Monday after Sunday, and so forth.
Calculating Planetary Hours
Historically, practitioners used astronomical tables and careful calculations.
Today, software and mobile applications perform these calculations instantly using your location and the day's sunrise and sunset times.
However, understanding the underlying method is valuable.
Suppose:
- sunrise: 6:00 AM
- sunset: 6:00 PM
Daylight would be exactly 12 hours long. Each daylight planetary hour is therefore 60 minutes long.
If sunrise was at 5:30 AM and sunset at 8:30 PM, daylight lasts fifteen hours. Each planetary daylight hour becomes:
15 ÷ 12 = 1.25 hours
Each planetary hour now lasts 75 minutes.
The same process is repeated for nighttime.
Understanding this explains why planetary hour charts differ every day of the year.
Choosing the Right Planet
The heart of planetary magic lies in selecting the planet whose symbolic qualities best match the intention of the work.
The Moon
The Moon governs cycles, intuition, dreams, fertility, emotional healing, psychic development, and divination.
Practitioners commonly choose Monday or a Moon hour for:
- Dream incubation
- Scrying
- Spirit communication
- Water magic
- Emotional healing
- Blessing family relationships
Mercury
Mercury rules communication and movement.
Mercury hours are excellent for:
- Writing
- Studying
- Learning languages
- Sending important messages
- Negotiations
- Divination
- Road-opening work
- Business planning
Venus
Venus extends beyond romantic love.
Traditional Venus magic also concerns:
- Friendship
- Harmony
- Reconciliation
- Artistic inspiration
- Beauty
- Fertility
- Music
- Social grace
Friday Venus hours are especially popular for blessing perfumes, jewellery, musical instruments, or artwork.
The Sun
Solar magic seeks increase, vitality, honour, and illumination.
A Sunday Sun hour may be chosen for:
- Healing rituals
- Confidence work
- Leadership
- Success
- Consecrating magical tools
- Spiritual purification
Mars
Mars is often misunderstood as representing only conflict.
Its healthier expressions include:
- Courage
- Determination
- Protection
- Physical strength
- Justice
- Breaking obstacles
Mars hours are frequently selected for protective talismans, defensive workings, or rituals requiring decisive action.
Jupiter
Jupiter has long been regarded as the planet of beneficence.
Thursday Jupiter hours support:
- Prosperity
- Career advancement
- Education
- Legal matters
- Generosity
- Spiritual growth
- Leadership
Many traditional prosperity talismans are created during Jupiter hours.
Saturn
Saturn represents discipline, structure, boundaries, endurance, age, and ancestral wisdom.
Although beginners sometimes avoid Saturn because of its association with limitation, experienced practitioners often regard it as one of the most profound planetary forces.
Saturn hours may be used for:
- Banishing
- Ending unhealthy habits
- Protection through boundaries
- Ancestor veneration
- Meditation
- Long-term commitments
- Stability
Combining Planetary Correspondences
Planetary timing becomes even more effective when combined with other traditional correspondences.
Suppose you wish to create a prosperity talisman.
Rather than simply performing the ritual at a convenient time, you might intentionally align several Jupiter correspondences:
- Thursday
- Jupiter hour
- Blue or royal purple candle
- Cedar or nutmeg incense
- Tin (Jupiter's traditional metal)
- Oak leaves
- Prayer for abundance or wise stewardship
The ritual becomes a unified expression of Jupiter's symbolism.
Likewise, a Venus working might combine:
- Friday
- Venus hour
- Rose petals
- Copper
- Green or pink candles
- Rose incense
- Music
- Fresh flowers
Traditional magical texts repeatedly encourage this kind of layered correspondence.
A Simple Practice for Beginners
Planetary magic need not begin with elaborate ceremonies.
One of the most useful exercises is simply becoming aware of the rhythm of the week.
For one month, choose one small activity aligned with each day's planetary ruler.
For example:
- Monday: Keep a dream journal.
- Tuesday: Exercise or perform a protective prayer.
- Wednesday: Study a magical text.
- Thursday: Donate to charity or work on financial planning.
- Friday: Create art or spend time nurturing relationships.
- Saturday: Clean your altar or honour your ancestors.
- Sunday: Meditate, pray, or spend time outdoors in sunlight.
This practice develops familiarity with planetary qualities before incorporating more formal ritual timing.
An Example Ritual
Imagine you wish to bless a journal dedicated to divination.
Mercury would be the obvious planetary choice because of its associations with writing, language, learning, and communication.
You might therefore choose:
- Wednesday.
- A Mercury planetary hour shortly after sunrise.
- Yellow or orange candles.
- Frankincense or lavender incense.
- A feather or quill placed beside the journal.
- A prayer asking for clarity, truthful insight, and wisdom.
The ritual itself need not be elaborate. What matters is that every element—including the timing—supports the same intention.
While there are programs and apps that calculate planetary hours for you, I recommend you first learn how to do it manually. When I first started practicing magic, I would always think of Tuesday being the day of Mercury, and Wednesday being the day of Mars. By calculating planetary hours manually, it helped me to memorize the correct order of both planetary days and planetary hours. I now use ChronosXP, an old but simple and accurate program that you can download on your computer. It has preset coordinates for a limited number of cities across the globe, but you can input the latitude and longitude of your exact location for accurate results.
