Hora is one of the oldest ways of dividing the day, and it quietly explains something familiar: the order of the weekdays. The word is related to ahoratra (day-and-night), and each hora is ruled by one of the seven visible planets.
Twelve by day, twelve by night
There are 24 horas in a Hindu day. The daytime (sunrise to sunset) is split into 12 equal horas and the night (sunset to next sunrise) into another 12. These are not 60-minute clock hours: in summer the day horas are longer than an hour and the night horas shorter, and in winter the reverse. Only near the equinoxes are they close to 60 minutes each.
The planetary sequence
Horas follow the Chaldean order, which arranges the planets by their apparent speed from slowest (Saturn) to fastest (Moon); starting the cycle from the Sun, it reads:
- Sun
- Venus
- Mercury
- Moon
- Saturn
- Jupiter
- Mars
The first hora after sunrise is ruled by the lord of the weekday — the Sun on Sunday, the Moon on Monday, Mars on Tuesday, and so on. The sequence then continues through the order above. After 24 horas the cycle has advanced three steps, so the next sunrise begins with the next weekday's lord: Sunday's Sun hora leads, 24 horas later, to Monday's Moon hora. This is how the weekday order itself arises.
Qualities used on this site
Different purposes favour different horas — for example, Mercury for study or trade, Venus for arts and relationships, Jupiter for learning and religious work. As a simple summary, this platform tags each hora with a general quality:
- Jupiter — auspicious
- Moon, Mercury, Venus — good
- Sun — neutral
- Mars, Saturn — inauspicious
These tags are a broad guide. Many traditions choose a hora according to the specific task instead, so a Mars hora may be preferred for some vigorous activities and a Saturn hora for others. Traditions may vary by region and Panchang convention.
How this platform calculates it
We calculate sunrise, sunset and the next sunrise for your location, divide day and night into 12 parts each, and start from the weekday lord. See today's horas on the Hora page, or compare with Choghadiya.
