Hora Today — Free Planetary Hour Calculator

A Hora (होरा) is a planetary hour — one of 24 sub-divisions of a civil day (sunrise to next sunrise) in Vedic muhurta shastra. Each hora is ruled by one of the 7 traditional planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn) and inherits that planet's nature. Choosing a task-aligned hora is one of the easiest forms of muhurat selection — no birth chart required, only date + place.

The day-arc from sunrise to sunset is split into 12 equal day-horas (≈60 min each, varying with season). The night-arc from sunset to next sunrise gives 12 night-horas. The first hora at sunrise is ruled by the day's planetary lord (Sunday=Sun, Monday=Moon, Tuesday=Mars, Wednesday=Mercury, Thursday=Jupiter, Friday=Venus, Saturday=Saturn). Subsequent horas cycle through the Chaldean order: Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon → repeat.

Sun hora — government work, authority dealings, health. Moon hora — travel (especially over water), public matters, agriculture. Jupiter hora — religion, teaching, marriage, learning, charity (greatest benefic). Venus hora — romance, art, music, weddings, luxury purchases. Mercury hora — communication, study, trade, signing contracts. Mars hora — surgery, lawsuits, sports (use sparingly). Saturn hora — hard labor, mining, agriculture, Shani remedies (use sparingly).

In Vedic + Hellenistic tradition, the 7-day week itself is derived from the planetary hora cycle. Each weekday is named after the planet ruling its first daylight hora — that's why Sunday is Sun-day, Monday is Moon-day, Saturday is Saturn-day, etc. The Chaldean order ensures that after 24 horas the next sunrise lands on exactly the next weekday's lord — a mathematically elegant 168-hour cycle.

All three are daily muhurat tools but use different time divisions. Hora = 24 hourly windows by planetary rulership. Choghadiya = 16 windows of ~90 min each (8 day + 8 night) classified Amrit/Shubh/Labh/etc. Rahu Kalam = 3 inauspicious ~90-min windows (Rahu/Yamaganda/Gulika) per day. For best muhurat: pick a Hora favorable to your planet/task, falling inside an auspicious Choghadiya, avoiding all three Rahu Kalam windows.

Sunrise + sunset computed via the Almanac for Computers algorithm (~1 minute accuracy at most latitudes). Hora boundaries are exact arithmetic divisions of the day/night arc. The Chaldean planetary sequence is a fixed mathematical rule — every Vedic + Western traditional astrologer uses the same order. Results match published Hora charts in standard panchangs.
