What are Planetary Hours (and Why “Today” Matters)?

Planetary hours divide the day and night into unequal blocks of time governed by seven classical planets: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon. Unlike the clock’s fixed 60-minute hour, each planetary hour expands or contracts with the season because it’s calculated from the actual length of daylight and nighttime at your location. That’s why the query “planetary hours today” is inherently location-based and date-specific.

In practice, that means your planetary hours for today in Delhi will be different from the planetary hours NYC visitors see, and different again from planetary hours Los Angeles. If you rely on planetary hours for timing communication, launches, meditation, or ritual, accuracy depends on using your current sunrise and sunset and your current timezone.

How Planetary Hours Are Calculated Today

Each calendar day is split into two sequences:

  1. Day hours: from today’s sunrise to today’s sunset, divided into 12 equal planetary hours.
  2. Night hours: from today’s sunset to tomorrow’s sunrise, divided into 12 equal planetary hours.

The sequence of rulers follows the classical Chaldean order: Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon, repeating in a loop. The first hour after sunrise is ruled by the day ruler (e.g., Sunday = Sun, Monday = Moon, etc.), and the cycle continues hour by hour. Because daylight and night lengths change through the year and vary by latitude, each hour’s duration changes too.

A precise planetary hours calculator uses:

  • Your latitude/longitude (or city) to compute today’s sunrise and sunset,
  • Your current timezone (including daylight saving),
  • The date (today’s date) to generate the planetary hours chart.

That’s why fast, client-side calculation is ideal: your browser can fetch geolocation (with permission) and apply time rules instantly, producing current planetary hours without server delays.

How to Use the Planetary Hours Calculator (Step-by-Step)

  1. Open the Planetary Hours Calculator.
  2. Click “Use my location” or choose a city from the list (e.g., planetary hours NYC, planetary hours Los Angeles).
  3. Confirm the date is set to and the timezone shows your timezone.
  4. Press “Calculate” to generate the planetary hours for today along with the ruling planet for each hour.
  5. Use the resulting planetary hours chart to schedule tasks aligned with planetary qualities:
    • Sun hours: visibility, leadership, launches.
    • Moon hours: care, intuition, reflection.
    • Mercury hours: communication, commerce, study.
    • Venus hours: relationship, art, harmony.
    • Mars hours: action, competition, courage.
    • Jupiter hours: growth, opportunity, teaching.
    • Saturn hours: discipline, structure, long-term plans.

If you’re viewing this page at night, remember the “night hours” span from today’s sunset to tomorrow’s sunrise. The calculator will label them clearly as Night Hour 1–12 to avoid confusion.

Why Location Pages Improve Accuracy (and SEO)

Many users search for city-specific results like “planetary hours NYC” or “planetary hours Los Angeles.” To serve those intents, we maintain location guides that preload the calculator with the right timezone and coordinate defaults:

These pages prevent duplication by pointing back to this canonical “today” guide and keep load times fast by relying on client-side logic. If you’re elsewhere, simply use the calculator’s location selector to get planetary hours for today where you are.

Accuracy Tips for Today’s Planetary Hours

  • Check timezone/dst: Make sure your browser time and site time match.
  • Sunrise type: Civil vs. astronomical sunrise can differ; calculators typically use standard sunrise/sunset definitions consistent with most ephemerides.
  • Geolocation permission: Allowing location access improves precision versus relying on IP-based approximations.
  • Date rollover: After midnight (before sunrise), you’re still in the night hours begun at yesterday’s sunset. The calculator handles this automatically.

Common Mistakes (and Quick Fixes)

“All hours look the same length.” Planetary hours are almost never 60 minutes; if you see uniform 60-minute blocks, check your sunrise/sunset inputs or timezone settings.

“Day hours start at noon.” They start at sunrise, not 12:00. If your day appears to begin at midday, the sunrise value is wrong (often caused by a mismatched timezone or a blocked geolocation prompt).

“The sequence looks off.” Verify the weekday and the day ruler. For example, Monday starts with a Moon hour at sunrise; Sunday starts with a Sun hour.

Planetary Hours Today — Live Calculator, How They’re Calculated & What Each Hour Means

Planetary hours are one of the oldest timekeeping systems in astrology and magic. They divide the day and night into 12 unequal hours each and assign each hour to a ruling planet using the ancient Chaldean Order (Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon).

If you want to check the current planetary hour, calculate the planet ruling this hour, or learn how planetary hours work, this guide gives you everything — including a live calculator, manual calculation method, meanings, use cases, and city-specific hour charts.

How Planetary Hours Are Calculated (Sunrise → Sunset → Night)

Planetary hours are based on local sunrise, sunset, and the ancient timekeeping system known as the Chaldean Order.

Step 1 — Get Local Sunrise & Sunset

Planetary hours depend on your latitude, date, and time zone.

Because sunrise and sunset change daily, planetary hours also change every day and are not fixed 60-minute blocks.

Step 2 — Divide Daylight Into 12 Unequal “Hours”

Formula:

Daytime Hour Length = (Sunset - Sunrise) ÷ 12

Example:
Sunrise: 6:20 AM
Sunset: 18:00 PM
Day length = 11h 40m → each planetary hour = 58 minutes 20 seconds

Step 3 — Divide Nighttime Into 12 Unequal Hours

Nighttime has its own length.
Formula:

Nighttime Hour Length = (Next Sunrise - Sunset) ÷ 12

Example:
Sunset: 18:00
Next Sunrise: 6:15 → Night = 12h 15m
Each night hour ≈ 61.25 minutes

Why They’re Unequal

Because sunrise and sunset shift through the year, daytime hours are longer in summer and shorter in winter, while nighttime hours do the opposite.


The Chaldean Order — Planetary Rulers Explained

Planetary hours follow the ancient Chaldean Order, based on the apparent speed of planets:

Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon (repeat)

Each day is named after the planet ruling its first hour:

  • Sunday → Sun
  • Monday → Moon
  • Tuesday → Mars
  • Wednesday → Mercury
  • Thursday → Jupiter
  • Friday → Venus
  • Saturday → Saturn

Example — New York (Assume Today’s Data)

  • Sunrise: 6:38 AM
  • Sunset: 17:03 PM
  • Day length: 10h 25m
  • Each day hour: 10h 25m ÷ 12 = ~52 minutes

Then apply the Chaldean order starting with the planet of the day:

For Monday:

  • 1st hour: Moon
  • 2nd hour: Saturn
  • 3rd: Jupiter
  • 4th: Mars
  • … continue until hour 12
    Then repeat sequence for nighttime hours.
