Long before modern astrology apps, magicians looked at the seven visible wandering lights in the sky and saw distinct forces at work in human life. Planetary magick is the practice of aligning a spell with the planet whose nature matches your goal, so the ritual draws on a coherent current of energy rather than a vague wish. In this guide you will learn what each classical planet governs, its traditional correspondences, and how to time your work so it moves with the sky instead of against it.
What Is Planetary Magick?
The classical tradition, which runs from Hellenistic astrology through the medieval grimoires and into the Renaissance, recognised seven planets: the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn. They were the only bodies visible to the naked eye that moved against the fixed stars, and each one was seen as ruling particular areas of life, materials, colours, days and even hours.
The core idea is sympathy. Everything on earth was believed to correspond to something in the heavens. Copper resonates with Venus, iron with Mars, gold with the Sun. When you gather the right materials, choose the right colour and act at the right time, you create a chain of correspondences that links your ritual to the planetary force you are calling on.
This is why planetary work feels so structured. It is less about inventing something new and more about tuning in to a frequency that the tradition has mapped carefully over many centuries.
The Seven Classical Planets at a Glance
The table below shows the most widely used correspondences. Different traditions vary slightly, especially on colours, so treat this as a reliable starting point rather than a rigid rulebook.
| Planet | Day | Colour | Metal | Governs |
|---|---|---|---|---|
| Sun | Sunday | Gold, yellow | Gold | Success, vitality, recognition, confidence |
| Moon | Monday | Silver, white | Silver | Intuition, dreams, home, emotions, cycles |
| Mars | Tuesday | Red | Iron | Courage, protection, drive, competition |
| Mercury | Wednesday | Orange, mixed colours | Quicksilver | Communication, study, trade, travel |
| Jupiter | Thursday | Royal blue, purple | Tin | Abundance, expansion, wisdom, good fortune |
| Venus | Friday | Green, pink | Copper | Love, beauty, harmony, friendship, pleasure |
| Saturn | Saturday | Black, indigo | Lead | Boundaries, endings, discipline, long-term structure |
What Each Planet Brings to Your Spells
The Sun: radiance and success
The Sun is the centre of the system and the source of life. In magick it rules visibility, personal power, health of spirit and the kind of success that comes with being seen and recognised. Solar work suits career advancement, confidence and any goal where you want to shine.
The Moon: intuition and the inner world
The Moon governs the tides of feeling, memory, dreams and the home. It is the planet of receptivity and psychic sensitivity. Because it moves so quickly, its phases also act as a timing tool for almost every kind of work, which we explore in our guide to moon magick and the best days for casting spells.
Mars: courage and protection
Mars is raw energy, will and the warrior spirit. It is called on for courage, for defending what is yours and for breaking through resistance. Martial energy is powerful and hot, so it is best used with clear intention and a calm hand.
Mercury: words, trade and movement
Mercury is the messenger. It rules speech, writing, study, negotiation, commerce and travel. Mercurial magick suits exams, contracts, job applications and any situation where clear communication will make the difference.
Jupiter: abundance and expansion
Jupiter is known in the old texts as the Greater Benefic. It expands whatever it touches and is associated with generosity, prosperity, wisdom and good fortune. Many practitioners regard it as the natural ally for long-term wealth and growth, and a dedicated Jupiter spell is one of the classic ways to invite that expansive energy.
Venus: love and harmony
Venus is the Lesser Benefic, the planet of attraction, affection, art and pleasure. It governs romantic love but also friendship, reconciliation and the general sweetness of life. Venusian work opens hearts and smooths relationships rather than forcing anything.
Saturn: structure and endings
Saturn is often misunderstood as purely malefic. In practice it is the planet of time, limits and consequences. It is called on to end what needs to end, to break bad habits, to build lasting foundations and to set firm boundaries. Saturnine magick is slow and serious, and it rewards patience.
Timing With Planetary Days and Hours
The simplest way to work with the planets is to cast on their day. A love working on a Friday, a prosperity ritual on a Thursday, a courage spell on a Tuesday: this alone adds a meaningful layer of alignment.
For more precision, practitioners use planetary hours. Each day and night is divided into twelve unequal “hours” between sunrise and sunset, and sunset and the next sunrise. The first hour after sunrise belongs to the ruler of that day, and the rest follow in the Chaldean order:
- Saturn
- Jupiter
- Mars
- Sun
- Venus
- Mercury
- Moon
The sequence then repeats. So on a Friday, the first hour after sunrise belongs to Venus, the second to Mercury, the third to the Moon and so on. Casting a Venus spell on a Friday in a Venus hour doubles the alignment. Because the hours depend on your local sunrise and sunset, their length changes through the year, so it is worth using a reliable calculator for your location.
How to Choose the Right Planet for Your Goal
Most goals have one obvious ruler, but it pays to look a little deeper. Ask yourself what the situation actually needs:
- Do you need something to grow? Jupiter or the Sun.
- Do you need something to end or be contained? Saturn.
- Do you need to speak up, persuade or learn? Mercury.
- Do you need to attract affection or restore harmony? Venus.
- Do you need strength, defence or momentum? Mars.
- Do you need insight, emotional healing or peace at home? The Moon.
Consider a money problem. If the issue is simply that income needs to expand, Jupiter fits. If the problem is that you keep missing opportunities because you undersell yourself, Mercury or the Sun may be more relevant. If old debts and habits are the root, Saturn may be the planet to start with. This kind of thinking is what turns a generic ritual into a precise one.
Combining Planetary Forces
Experienced practitioners sometimes layer planets. A business working might use Mercury for marketing and negotiation alongside Jupiter for growth. A relationship working might pair Venus for affection with the Moon for emotional healing.
Layering should be done thoughtfully. Some combinations support each other easily, while others pull in different directions; Mars and Venus, for example, can create passion or friction depending on how they are handled. When in doubt, a single, well-chosen planet is usually stronger than a crowded altar.
In professional practice, the next step is often to consult the client’s natal chart and the current transits. That is the territory of astrological magick, where the timing is chosen not only by day and hour but by where the planets stand in relation to your own birth chart.
What About Uranus, Neptune and Pluto?
The outer planets were discovered long after the classical system took shape, so they have no traditional day or metal. Modern practitioners do work with them: Uranus for sudden change and breakthroughs, Neptune for dreams and spiritual vision, Pluto for deep transformation. They tend to be used for specialised work, while the seven classical planets remain the backbone of most rituals. You can see both classical and modern options in our range of planetary candle spells.
Frequently Asked Questions
Do I need to know astrology to use planetary magick?
No. You can begin simply by matching your goal to a planet and casting on that planet’s day, using its colour for your candle. Planetary hours add precision and are easy to look up. A full natal chart becomes useful for more advanced or professional work, but the basics are accessible to anyone willing to learn the correspondences.
What happens if I cast a spell on the wrong day?
Nothing harmful. Planetary timing is about adding support, not about rigid rules. A spell cast on a less ideal day still carries your intention and focus; it simply does not benefit from the extra alignment. If your situation is urgent, you can use the matching planetary hour on another day as a good alternative.
Which planet is best for money?
Jupiter is the traditional planet of abundance and expansion, so it is the most common choice. The Sun supports success and recognition, Mercury governs trade and negotiation, and Saturn helps with long-term stability and clearing debt. The best choice depends on what is actually holding your finances back, which is why diagnosing the situation first is so helpful.
Is planetary magick the same as astrology?
They are closely related but not identical. Astrology interprets planetary positions to understand character and timing. Planetary magick uses those same forces actively, through ritual, colour, metal and timing, to support a specific goal. Many practitioners use astrology to plan their workings, but you can practise the magickal side without becoming an astrologer.
