Planetary Hours: Ancient Timing System for Spells

The Most Precise Magical Timing Tool You're Not Using
Imagine you want to do a love spell. You know to do it on a Friday (Venus day) during the waxing moon. But here's what most practitioners miss: not all hours of Friday carry Venus energy.
Friday has 24 hours. Only 3-4 of those hours are actually ruled by Venus. The rest? They cycle through Saturn, Jupiter, Mars, Sun, Mercury, and Moon. If you do your Venus love spell during a Saturn hour (restriction, limitation), you're working against yourself.
This is where planetary hours come inβthe ancient timing system that divides each day into 24 hours, each ruled by a different planet. It's the most precise magical timing tool available, and once you understand it, you'll never cast a spell without checking the planetary hour first.
Welcome to the second article in our Temporal Magic series. Today, we're diving deep into planetary hours: what they are, how they work, how to calculate them, and how to use them to supercharge your spellwork.
What Are Planetary Hours?
The System:
Planetary hours are an ancient Hellenistic astrological system that assigns each hour of the day to one of the seven classical planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn). The system has been used for over 2,000 years in astrology, magic, and alchemy.
The Structure:
- Each day has 24 planetary hours (not the same as clock hours)
- 12 day hours (sunrise to sunset)
- 12 night hours (sunset to sunrise)
- Each hour is ruled by one of the seven planets
- The planets cycle in a specific order called the Chaldean order
Key Point:
Planetary hours are not 60-minute clock hours. They're variable-length hours that change with the seasons. In summer, day hours are longer than night hours. In winter, night hours are longer than day hours. Only at the equinoxes are they equal.
The Chaldean Order: The Planetary Sequence
The planets cycle through hours in the Chaldean orderβan ancient sequence based on the apparent speed of the planets from Earth's perspective (slowest to fastest):
Saturn β Jupiter β Mars β Sun β Venus β Mercury β Moon
Then it repeats: Saturn β Jupiter β Mars β Sun β Venus β Mercury β Moon...
Why This Order?
The Chaldeans observed that Saturn (the slowest planet) takes about 29 years to orbit the Sun, while the Moon (fastest) takes only 29 days. This order reflects the cosmic hierarchy from slowest/heaviest to fastest/lightest.

How Planetary Hours Work: The Day Ruler System
The First Hour Rule:
The first hour after sunrise is always ruled by the planet that rules that day of the week.
The Days and Their Rulers:
- Sunday: Sun
- Monday: Moon
- Tuesday: Mars (from "Mardi" in French, "Martes" in Spanish)
- Wednesday: Mercury (from "Mercredi" in French, "MiΓ©rcoles" in Spanish)
- Thursday: Jupiter (from "Jeudi" in French, Thor/Jupiter connection)
- Friday: Venus (from "Vendredi" in French, "Viernes" in Spanish)
- Saturday: Saturn
Example: Friday (Venus Day)
- Hour 1 (sunrise): Venus (the day ruler)
- Hour 2: Mercury (next in Chaldean order)
- Hour 3: Moon
- Hour 4: Saturn
- Hour 5: Jupiter
- Hour 6: Mars
- Hour 7: Sun
- Hour 8: Venus (cycles back)
...and so on through all 24 hours.
The Pattern:
Because there are 7 planets and 24 hours, the pattern doesn't repeat evenly within a day. This is why each day of the week starts with a different planetβthe mathematical relationship between 7 and 24 creates the weekly cycle.
How to Calculate Planetary Hours (The Manual Method)
Step 1: Find Sunrise and Sunset Times
Use a website like timeanddate.com or a weather app to find the exact sunrise and sunset times for your location on the day you're working.
Example (January 1, 2026, Chicago):
- Sunrise: 7:18 AM
- Sunset: 4:32 PM
Step 2: Calculate Day Hour Length
Subtract sunrise from sunset, then divide by 12.
4:32 PM - 7:18 AM = 9 hours 14 minutes = 554 minutes
554 Γ· 12 = 46.17 minutes per day hour
Step 3: Calculate Night Hour Length
Subtract day length from 24 hours, then divide by 12.
24 hours - 9 hours 14 minutes = 14 hours 46 minutes = 886 minutes
886 Γ· 12 = 73.83 minutes per night hour
Step 4: List the Hours
Starting with the day ruler (Thursday = Jupiter), cycle through the Chaldean order.
Thursday, January 1, 2026 (Chicago):
Day Hours (each 46 minutes):
1. Jupiter (7:18 AM - 8:04 AM)
2. Mars (8:04 AM - 8:50 AM)
3. Sun (8:50 AM - 9:36 AM)
4. Venus (9:36 AM - 10:22 AM)
5. Mercury (10:22 AM - 11:08 AM)
6. Moon (11:08 AM - 11:54 AM)
7. Saturn (11:54 AM - 12:40 PM)
8. Jupiter (12:40 PM - 1:26 PM)
9. Mars (1:26 PM - 2:12 PM)
10. Sun (2:12 PM - 2:58 PM)
11. Venus (2:58 PM - 3:44 PM)
12. Mercury (3:44 PM - 4:30 PM)
Night Hours (each 74 minutes):
1. Moon (4:32 PM - 5:46 PM)
2. Saturn (5:46 PM - 7:00 PM)
...and so on.

Level 2 (Intermediate): Planetary day + Planetary hour + Moon phase
Level 3 (Advanced): Planetary day + Planetary hour + Moon phase + Moon sign
Level 4 (Master): All of the above + Avoid void of course Moon + Check for retrogrades

Common Mistakes with Planetary Hours
Mistake 1: Using Clock Hours Instead of Planetary Hours
Planetary hours are NOT 60-minute blocks. They vary by season and location. Always calculate or use an app.
Mistake 2: Ignoring the Day Ruler
Even if you find a Venus hour on Tuesday (Mars day), the overall day energy is still Mars. For best results, match the day AND the hour.
Mistake 3: Obsessing Over Perfection
Don't let perfect timing prevent you from acting. If you can't get the perfect planetary hour, at least get the right day and moon phase. Something is better than nothing.
Mistake 4: Forgetting Your Location
Planetary hours are based on YOUR local sunrise/sunset, not a generic time zone. Always use your specific location.
