What Hora is
A hora is a planetary hour. Daylight is divided into twelve parts and the night into twelve more, and each is ruled by a planet running in the Chaldean order — Sun, Venus, Mercury, Moon, Saturn, Jupiter, Mars — repeating. The first hora after sunrise always belongs to the ruler of that weekday, which is why Friday opens with a Venus hora.

What each hora is used for
Traditionally, each planet's hour suits a different kind of work.
- Jupiter — study, ceremony, and anything needing goodwill
- Mercury — paperwork, trade and communication
- Venus — art, purchases and relationships
- Moon — travel and matters of the home
- Sun — dealing with authority
- Mars and Saturn — hard, solitary work rather than new beginnings
A hora is a timing convention, not a forecast.

Frequently asked
- How long is one hora?
- Not a clock hour. Daylight is split into twelve equal parts and night into twelve, so a hora runs longer than sixty minutes in summer daylight and shorter in winter — and day and night horas differ in length on the same date.
- Which hora is running now?
- Match the current time against the day table above (sunrise to sunset) or the night table (sunset onwards). Both are given in local time for New Delhi, India (IST).
- Why does the day start with a different planet each weekday?
- Because the weekday is named for the planet ruling its first hora — Sunday opens with a Sun hora, Monday with the Moon, and so on. The sequence then continues in Chaldean order through all twenty-four.
