What Are Planetary Hours?

Planetary hours are based on the Chaldean Order of the Planets: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon. This sequence repeats throughout the day and night.

• Each day starts at sunrise, and the planet ruling that day sets the tone.
• For example, Sunday begins with the Sun, Monday with the Moon, and so on.
• From there, the order cycles every hour, creating a rhythm of planetary influences.

Because day and night vary with the seasons, planetary hours aren’t always 60 minutes long. They expand during longer days and contract during shorter ones.

Why Use a Planetary Hours Calculator?

Calculating planetary hours by hand involves sunrise times, sunset times, and some math. Our calculator saves you the effort by using a simplified model (fixed 6 AM–6 PM for daytime and 6 PM–6 AM for nighttime). This makes it quick, easy, and beginner-friendly.

Here are a few ways you can use planetary hours in daily life:

• 🌞 Sun Hours – Best for leadership, confidence, and visibility.
• 🌙 Moon Hours – Perfect for intuition, emotions, and self-care.
• 🔥 Mars Hours – Good for action, courage, and physical energy.
• 💎 Venus Hours – Ideal for love, beauty, and creativity.
• 📚 Mercury Hours – Support communication, study, and travel.
• 💰 Jupiter Hours – Bring expansion, luck, and growth.
• 🪐 Saturn Hours – Encourage discipline, structure, and long-term planning.

How the Planetary Hours Calculator Works

Using the calculator is simple:

1. Select the Date – Pick any day you want to analyze.
2. Enter the Time – Add the specific hour and minute.
3. Click Calculate – Instantly see which planet rules that hour.

You’ll also get a short description of how that planet’s energy influences the time.

Example: Entering 10:00 AM on Tuesday will show Mars as the planetary hour ruler, since Tuesday is ruled by Mars and the cycle continues from there.

Why Planetary Hours Matter in Modern Life

You don’t have to be an astrologer to use planetary hours. Many people align their activities with these cycles for better results. Imagine scheduling an important meeting during a Mercury hour for clarity, or beginning a fitness routine during a Mars hour for motivation. Even if you treat it as a mindfulness tool, planetary hours add rhythm and intention to your day.
