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.

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 Sunday opens with a Sun hora.

Day Hora (Sunday)

From sunrise to sunset: Sun 06:23–07:20, Venus 07:20–08:17, Mercury 08:17–09:14, Moon 09:14–10:11, Saturn 10:11–11:08, Jupiter 11:08–12:06, Mars 12:06–13:03, Sun 13:03–14:00, Venus 14:00–14:57, Mercury 14:57–15:54, Moon 15:54–16:51, Saturn 16:51–17:48.

What each hora is used for

Traditionally: Jupiter hora for study, ceremony and anything needing goodwill; Mercury for paperwork, trade and communication; Venus for art, purchases and relationships; Moon for travel and matters of the home; Sun for dealing with authority. Mars and Saturn horas are usually left for hard, solitary work rather than new beginnings. A hora is a timing convention, not a forecast.
