Planetary hours for today, by day and by night
This planetary hours calculator lists today’s 24 planetary hours — the hora of Indian astrology — for any city, from the real local sunrise and sunset. The 12 day hours split daylight into twelve, the 12 night hours split the night, and each is ruled by one of the seven classical planets in the Chaldean order. Press Tomorrow or pick any date; the hour running now is highlighted.
Switch the wording between Hora (Surya, Chandra, Mangal, Budh, Guru, Shukra, Shani) and Western Planetary hours (“the hour of Venus”); the timings are the same in both traditions. This page is for tradition and entertainment, not prediction or advice.

Hora / Planetary Hours Calculator features
Unequal hours from real sunrise
Day hours are one-twelfth of today’s daylight and night hours one-twelfth of the night, so in a Delhi summer a day hora lasts about 66 minutes and a night hora 54.
Checked against a published panchang
The self-test compares all 24 horas for New Delhi and New York with a widely used online panchang, to within two minutes.
Highlight one planet
Mark every Venus, Jupiter or Mercury hour of the day; the panel shows when the next one begins.
Hora or planetary-hours wording
Sanskrit planet names for Indian users, or “planetary hour of Saturn” for the Western tradition.
Equal-hour option
Some regional almanacs count 60-minute horas from sunrise; one switch gives that table too.
How the planetary hours are calculated
The seven classical planets in the Chaldean order, from slowest to fastest, are Saturn, Jupiter, Mars, Sun, Venus, Mercury and Moon. The first hour after sunrise belongs to the planet that rules the weekday — Sunday the Sun, Monday the Moon, Tuesday Mars, Wednesday Mercury, Thursday Jupiter, Friday Venus, Saturday Saturn — and every following hour goes to the next planet in that order, wrapping round from the Moon back to Saturn.
Twenty-four hours later the sequence has advanced three planets, which lands exactly on the next weekday’s ruler: this is where the order of the weekdays comes from. Worked example for Thursday 14 August 2025 in New Delhi: sunrise 05:50, sunset 19:01, so a day hour is 13 h 11 min ÷ 12 ≈ 66 minutes. Hour 1 is Jupiter (05:50–06:56), then Mars, Sun, Venus, Mercury, Moon, Saturn, Jupiter again at 13:32, and the first night hour, from 19:01, is the Moon.
| Day | Ruler (hour 1) | Hour 2 | Hour 3 | First night hour |
|---|---|---|---|---|
| Sunday | Sun | Venus | Mercury | Jupiter |
| Monday | Moon | Saturn | Jupiter | Venus |
| Tuesday | Mars | Sun | Venus | Saturn |
| Wednesday | Mercury | Moon | Saturn | Sun |
| Thursday | Jupiter | Mars | Sun | Moon |
| Friday | Venus | Mercury | Moon | Mars |
| Saturday | Saturn | Jupiter | Mars | Mercury |
Hora in Indian astrology and planetary hours in the West
The same scheme appears in Hellenistic astrology, in medieval European magic books and in Indian texts, where each hour is a hora — the word that gave English “hour”. Indian almanacs print a hora table next to the choghadiya, and many people choose a Jupiter (Guru) or Venus (Shukra) hora for a ceremony or purchase; the Western tradition attaches similar meanings to “the hour of Venus” or “the hour of Mars”. The associations in the table are the usual textbook keywords, not advice. For a date search using tithi and nakshatra, use the muhurat finder.
Limits and differences between tables
Times depend on how sunrise is defined; this page uses the Sun’s upper edge with standard refraction, the panchang convention, so other sites may differ by a minute. Inside the polar circles there are days without sunrise or sunset, and the hours cannot be defined — the page says so. A few Tamil and Kerala almanacs use fixed 60-minute horas from a 6 am sunrise; choose equal hours and set the city to compare. See the sunrise and sunset calculator for the underlying times.
Hora / Planetary Hours Calculator FAQ

Open the page: it shows today’s 12 day and 12 night planetary hours for your chosen city, with the current hour highlighted.
What is hora time today?
The hora table above gives each hora’s start and end for today. The first hora after sunrise is ruled by the weekday’s planet.
How long is one planetary hour?
One-twelfth of the daylight or of the night, so it changes through the year — about 66 minutes by day in a Delhi summer and 47 in a New York winter.
Which planetary hour is good for buying something?
Tradition favours Venus (Shukra) and Jupiter (Guru) hours for purchases and ceremonies. Use Highlight to find them; it is a tradition, not a guarantee.
Why does my almanac show 60-minute horas?
Some regional almanacs use equal clock hours from sunrise. Choose Equal 60-minute hours to match them.
Do the Western planetary hours differ from hora?
No — both use the Chaldean order starting with the day ruler at sunrise. Only the names and meanings differ.
