Every moment belongs to a planetary hour.

But planetary hours are not fixed sixty-minute blocks. Their length changes with daylight, season, date, and location — which means the hour ruling this moment is unique to where you are.

Your hour is local. Your timing should be too.

Planetary hours follow the movement of the Sun rather than the mechanical clock.

From sunrise to sunset, daylight is divided into twelve seasonal hours. From sunset to the following sunrise, the night is divided into twelve more.

The rulers move through the traditional Chaldean order:

♄ Saturn · ♃ Jupiter · ♂ Mars · ☉ Sun · ♀ Venus · ☿ Mercury · ☽ Moon

Because sunrise and sunset change throughout the year — and from one location to another — planetary hours expand and contract with the season.

A Venus hour in London does not necessarily begin at the same moment as a Venus hour in Rome.

A Jupiter hour in June may last much longer than a Jupiter hour in December.

That is why accurate planetary timing begins with place, date, and the real solar day.

Start with the hour. Go as deep as you need.

Planetary Hours is designed to make traditional timing immediately readable without reducing it to a single planetary ruler.

More than a planetary hours calculator.

A planetary hour can tell you who rules the moment.

A fuller election asks much more.

  • Where is the ruler?
  • Is it direct or retrograde?
  • How is the Moon behaving?
  • What is applying next?
  • Which houses are emphasized?
  • Are the relevant planets strengthened — or impaired?
  • Do several testimonies point in the same direction?

Planetary Hours brings those layers together while keeping the first answer simple.

You can check the current hour in seconds.

You can also stay and investigate the moment.

Seven planets. Seven kinds of momentum.

Traditional planetary timing associates each of the seven classical planets with a distinct field of action.

  • Sun

    Visibility · Authority · Vitality

    Leadership, recognition, confidence, prominence, important decisions, and actions meant to be seen.

  • Moon

    Movement · Instinct · Change

    Home, daily life, care, public response, intuition, adaptation, travel, and matters that develop quickly.

  • Mercury

    Communication · Intelligence · Exchange

    Writing, study, commerce, negotiation, technology, analysis, messages, contracts, and information.

  • Venus

    Attraction · Harmony · Pleasure

    Love, friendship, reconciliation, beauty, art, diplomacy, enjoyment, and social connection.

  • Mars

    Action · Force · Separation

    Courage, competition, decisive action, physical effort, confrontation, cutting through obstacles, and severance.

  • Jupiter

    Expansion · Opportunity · Honor

    Growth, prosperity, advancement, wisdom, generosity, recognition, teaching, and long-term opportunity.

  • Saturn

    Structure · Endurance · Boundaries

    Discipline, responsibility, permanence, restriction, consolidation, serious commitments, and endings.

The planetary hour gives the moment a ruler.

The surrounding chart tells you how that ruler is able to act.

Good timing is rarely one-dimensional.

A beautiful Venus hour can occur while Venus itself is poorly placed.

A Jupiter hour can become far more compelling when Jupiter is strong, angular, supported by the Moon, and relevant to the matter being elected.

A seemingly ordinary hour can become remarkable when several independent conditions converge.

This is where planetary hours stop being a timetable and become electional astrology.

Planetary Hours lets you begin with the simplest traditional layer and progressively reveal the rest.

No need to choose between simplicity and depth.

Begin with the moment. Investigate what matters.

Ancient timing, calculated for the modern world.

  1. Choose a place and moment Search by city or use coordinates when precision matters. Local timezone and daylight-saving rules are resolved for the selected date.
  2. Follow the real solar day Sunrise and sunset define the boundaries of the planetary day. Daylight and nighttime are each divided separately into twelve seasonal hours.
  3. Read the ruler — or explore the whole sky Check the current planetary hour immediately, then open the deeper astrological layers whenever the decision calls for more than a simple answer.

Built for people who care when something begins.

  • For traditional astrologers.
  • For electional astrologers.
  • For practitioners working with planetary correspondences and ritual timing.
  • For researchers comparing historical astrological techniques.
  • And for anyone who has ever looked at a clock and wondered whether this is the right moment to act.
  • Use it for a quick planetary-hour check.
  • Use it to study a date.
  • Use it to compare possibilities.
  • Use it to search for a stronger beginning.

Precision without losing the tradition.

Traditional astrology contains layers.

Planetary days. Planetary hours. Lunar motion. Aspects. Houses. Essential and accidental conditions. Applications. Prohibitions. Strengths. Impediments.

A useful tool should not flatten all of that into a mysterious score.

It should make complexity readable.

Planetary Hours is built around that idea:

show the answer first, preserve the reasoning underneath it.

Simple when you need speed.

Detailed when you need evidence.

What are planetary hours?

Planetary hours are a traditional astrological system that divides daylight into twelve seasonal hours and nighttime into another twelve. Each hour is ruled by one of the seven classical planets according to the repeating Chaldean order.

Unlike ordinary clock hours, planetary hours are usually unequal in length because they are calculated from local sunrise and sunset.

The first planetary hour after sunrise is ruled by the planet associated with that weekday. The sequence then continues through Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon before repeating.

Because the calculation depends on sunrise and sunset, planetary hours depend on both date and location.

Frequently Asked Questions

What planetary hour is it right now?

The current planetary hour depends on your location, local sunrise and sunset, and the current time. Enter or detect your location to calculate the ruler of the present hour and see exactly when it begins and ends.

Are planetary hours always 60 minutes?

No. Traditional planetary hours are seasonal hours. Daylight is divided into twelve equal portions and nighttime into twelve separate portions, so their duration changes throughout the year.

Do planetary hours depend on location?

Yes. Because they are based on local sunrise and sunset, the exact beginning and end of each planetary hour changes with geographical location and date.

What is the Chaldean order?

The traditional planetary sequence is:
Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon
The sequence repeats continuously through the planetary hours.

Can planetary hours be used for electional astrology?

Yes. Planetary hours are one traditional layer of electional timing. More advanced elections can also consider the condition of the hour ruler, the Moon, aspects, houses, planetary strength, and other relevant testimonies.

Is a planetary hour enough to choose the best time?

Not always. For simple timing, the planetary hour may be all you need. For important elections, examining the wider chart can reveal whether the ruler of the hour is actually capable of supporting the intended action.

The sky changes. So does the quality of the moment.

Find the hour. Read the sky. Choose the moment.
