Hora

What is Hora?

Hora is the system of planetary hours, one of the oldest timing methods in astrology. The day from sunrise to the next sunrise is divided into 24 Horas, and each is ruled by one of the seven classical planets — Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. The ruling planet colours that hour and indicates the kind of activity it favours.

The word Hora is the root of the English "hour", and the system is shared across Vedic, Hellenistic and medieval European traditions — a rare point of direct overlap between them.

How Hora is Calculated

The first Hora of any day begins at sunrise and is ruled by the planet that governs that weekday: the Sun on Sunday, the Moon on Monday, Mars on Tuesday, Mercury on Wednesday, Jupiter on Thursday, Venus on Friday and Saturn on Saturday. This is the origin of the names of the days of the week in many languages.

Subsequent Horas follow the Chaldean order of planetary speed, from slowest to fastest: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon — repeating in a cycle. Because 24 hours divided among 7 planets leaves a remainder of three, the sequence naturally lands on the correct next weekday ruler at the following sunrise.

In the strict traditional method, a Hora is not exactly 60 minutes. The daylight span is divided into 12 equal parts and the night into 12, so Horas are longer than an hour by day in summer and shorter by night — the same "unequal hours" used in classical astrology.

What Each Hora Favours

• Sun Hora — authority, government work, dealings with superiors, matters of health and vitality.
• Moon Hora — travel over water, domestic matters, dealings with women, emotional and nurturing activity.
• Mars Hora — competition, surgery, physical exertion, property and land, disputes requiring assertion.
• Mercury Hora — communication, study, writing, accounting, negotiation and commerce.
• Jupiter Hora — teaching, finance, legal matters, ceremonies and any auspicious new beginning; widely regarded as the most benefic Hora.
• Venus Hora — marriage, art, music, purchases of luxury and beauty, romantic matters.
• Saturn Hora — labour, long-term commitments, dealings with elders; generally avoided for new ventures.

Using the Hora Calculator

Select your date and location to see the full 24-Hora table with exact start and end times for each period and its ruling planet, calculated from your local sunrise. Hora is often combined with Choghadiya for finer timing: an activity started in a favourable Choghadiya that also falls in a supportive Hora is considered doubly well-timed.

Frequently Asked Questions

Which Hora is best for starting new work?

Jupiter Hora is the most widely favoured for auspicious beginnings. Mercury Hora suits commercial and communication-based work, and Venus Hora suits matters of relationship and art. Saturn and Mars Horas are generally avoided for new ventures.

Is a Hora exactly one hour long?

Not in the traditional method. Daylight is divided into 12 equal parts and night into 12, so Hora length varies with the season and your latitude. Only near the equinoxes does a Hora approach a clock hour.

What is the difference between Hora and the Hora divisional chart?

They share a name but are unrelated. This page concerns planetary hours for timing. The D2 or Hora chart is a divisional chart used in Vedic astrology to assess wealth, produced by dividing each sign into two halves. You can view divisional charts from the Kundali section.

Do Hora timings change by city?

Yes. Since the sequence starts at local sunrise, both the start times and the lengths of the Horas depend on your coordinates and the date.
