Hora today in Lucknow

The twelve horas of the daytime run from sunrise to sunset and the twelve of the night from sunset to the next sunrise, so they are not exactly an hour long: in the months with long days the day horas are longer than 60 minutes and the night horas shorter, and in the months with short days the other way round. The ruling planets follow one fixed order through day and night without a break: Sun, Venus, Mercury, Moon, Saturn, Jupiter, Mars, then the Sun again.

The first hora after sunrise belongs to the planet of the weekday, which is why the weekday is named after it: the Sun on Sunday, the Moon on Monday, Mars on Tuesday, Mercury on Wednesday, Jupiter on Thursday, Venus on Friday and Saturn on Saturday.

Traditionally, the Sun's hora is used for matters of authority and official work, the Moon's for travel and dealings with the public, and Mars's for courage, property and anything that takes effort. Mercury's is for study, trade and communication, Jupiter's for learning, teaching and advice, Venus's for relationships, the arts and comfort, and Saturn's for patient, routine or repair work.

This is how the tradition describes them, and it is offered here as a way of looking at the day, not as a guide to what will go well.

Lucknow is about 1.5 degrees west of the Indian Standard Time meridian, so true local noon falls about 6 minutes after 12:00 by the clock.

Sunrise, sunset, moonrise and moonset come from the Navamsha astrology API; where it is not available they are computed by our own engine, which agrees with it to a fraction of a second. The moment each tithi, nakshatra, yoga and karana ends is computed by that engine from the positions of the Sun and Moon (NASA JPL DE421 ephemeris) in the sidereal zodiac with the Lahiri ayanamsa. Rahu Kaal, Choghadiya, Hora, Abhijit Muhurat and the other periods are fixed fractions of the day worked out from sunrise and sunset.

Almanacs differ in how they define sunrise. Here the Sun rises when the centre of its disc is on the horizon, with no allowance for refraction. Almanacs that use the Sun's upper edge and refraction show sunrise a few minutes earlier and sunset a few minutes later, and their Rahu Kaal and other periods move with it. For a ceremony, follow the Panchang your family priest or local temple uses.
