Choghadiya or hora: two ways of reading the same day

Choghadiya and hora are two ways the panchang, the traditional Hindu almanac, divides the same day. Both count from the local sunrise, but the choghadiya cuts the daylight and the night into eight parts each and gives every part one of seven traditional names, while the hora cuts each into twelve and gives every part to one of the seven grahas, the moving bodies of traditional astronomy that name the weekdays. Set side by side, the choghadiya vs hora question has a tidier answer than it first seems: the two read the same seven grahas around the same ring, at different grains.

This note compares how each divides the day, the grahas behind both, where they meet and drift apart, and what a reading does when they disagree. What either count favours is a preference for a beginning, not a forecast.

How choghadiya and hora divide the day

The choghadiya cuts the daylight, from sunrise to sunset, into eight equal parts, and the night, from sunset to the next sunrise, into eight more. Its name is usually explained as four ghadi, a traditional unit of about twenty-four minutes that the note on the ghati covers. Each part carries one of seven names. Tradition favours four: Amrit (nectar), Shubh (good), Labh (gain) and Char (moving). It sets aside the other three, Udveg (restlessness), Kaal (time) and Rog (illness), when choosing a time to begin something.

The hora cuts each half into twelve instead, and each hora belongs to one graha. Tradition explains the word as ahoratra, the Sanskrit for a full day and night, with its first and last syllables dropped; Tamil calendars write it horai.

Both counts are fractions of the real daylight and night, not fixed minutes, so they stretch and shrink together with the seasons, and a part always lasts one and a half horas.

The seven grahas behind both counts

The hora's grahas follow one fixed order, repeating without a break: Sun, Venus, Mercury, Moon, Saturn, Jupiter, Mars. The first hora after sunrise belongs to the lord of the weekday, the vara in a panchang, and the run continues through the night without restarting. What is a hora? shows how that order sets the days of the week.

The choghadiya names belong to the same seven: Udveg to the Sun, Char to Venus, Labh to Mercury, Amrit to the Moon, Kaal to Saturn, Shubh to Jupiter and Rog to Mars. Listed in that order, the names are the daytime loop and their grahas are the hora's ring. The first part of the day takes the name of the weekday's own graha, so both counts open the day together: Friday is Venus's day, and its daylight opens with Char and with a Venus hora. What is choghadiya? gives each weekday's opening names.

The verdicts follow the grahas too. The four favoured names belong to Venus, Mercury, the Moon and Jupiter, the gentler grahas whose horas tradition generally looks to for beginnings; the three set aside belong to the Sun, Saturn and Mars, whose horas it keeps for other kinds of work. Panchangs commonly explain the choghadiya this way, judging each part by the nature of the graha behind it.

The night keeps the pairing. On every weekday the first night name belongs to the graha of the first night hora: Friday's night opens with Rog, the part of Mars, and with a Mars hora.

Where the two counts meet, and where they part

Two choghadiya parts span exactly three horas, so every second choghadiya boundary is also a hora boundary: the counts meet at a quarter, a half and three quarters of the daylight, and the night repeats the pattern. The proportions hold in every season.

The grahas behave differently. By day both counts walk the ring one graha at a time, but a hora is two thirds of a part, so the hora draws ahead. Take an example Friday, in round illustrative figures rather than any real city, with sunrise at 6:00am and sunset at 6:00pm: each part lasts 90 minutes and each hora 60.

The first part names Venus in both counts, and the second pairs Labh with Mercury's hora for its first half hour. From the third part to sunset the hora never names the part's own graha: Amrit opens under Saturn's hora and Shubh under the Sun's. That is why the two counts so often disagree: a choghadiya name says which graha the part belongs to, the hora whose hour is running, and through most of the daylight those differ.

By night the choghadiya takes a longer stride, five places round the ring for each part, which brings the counts back into step: each odd-numbered night part opens with a whole hora of its own graha. Those night parts still belong to the day that began at sunrise, as the note on the Vedic day explains.

Reading the two together

The two counts answer slightly different questions. The choghadiya gives a broad verdict on beginnings, with a few names tied to particular undertakings, Char above all to travel and Shubh to ceremonies and first days. The hora is read more for the kind of work in hand: panchangs that describe the horas pair each graha with its own, Mercury with learning and Venus with music and the arts, for example, though the lists vary between sources.

Either count can be read alone, and how the two are weighed together varies by region, lineage and family. The cautious reading, and the one followed here, looks for stretches where they agree, a favoured name under a gentler graha's hora, and sets aside Rahu Kaal, Yamaganda and Gulika, three classical daytime periods that each fill one of the same eight parts, chosen by the weekday. On a Friday they take the fourth, seventh and second; the guide to Rahu Kaal, Yamaganda and Gulika gives every weekday's parts.

That leaves four stretches on the example Friday: the whole first part, Char from sunrise to 7:30am; Jupiter's hora from 10:00am to 10:30am, closing Amrit; Venus's hora from 1:00pm to 1:30pm in Shubh; and Jupiter's hora in the closing Char, from 5:00pm to sunset. Labh agrees throughout, but Gulika fills that part, so it is passed over. Where the counts disagree, as in the Saturn hour that opens Amrit, this reading waits for the gentler hora. Where your family follows its own panchang, follow it. The note on finding an auspicious time today adds the further layers a fuller reading weighs.

How Sumuhurta reads both

Sumuhurta, the iPhone and Android app this site is about, reads both counts and gives them different jobs. On the phone it calculates sunrise, sunset and the next sunrise for your place, and the choghadiya works as a gate: a minute can join a window only if it sits wholly inside an Amrit, Shubh, Labh or Char part and wholly outside Rahu Kaal, Yamaganda and Gulika. Inside that gate, the hora is one of the inputs that shape where a window falls, weighed with the abhijit muhurta around local noon and the Brahma muhurta before dawn against the birth chart entered on your phone. Its rule reads:

Every personal window Sumuhurta surfaces is calculated to avoid Rahu Kaal, Yamaganda, Gulika, and the Kaal, Rog and Udveg choghadiya periods.

So no hora, however gentle its graha, can carry a window into a Kaal, Rog or Udveg part. What comes out is not a table but one to three personal windows in each sunrise-to-sunrise cycle, day or night, running roughly twenty to a hundred and fifty minutes and never crossing sunrise or sunset. Each carries a plain-English quality, Clear run, Sharp or Steady, and a quiet attribution naming the hora and the choghadiya at its middle, in the form Venus hora · Char. Under Char, the window puts the tradition in plain words: For travel and setting out.

That rule is narrow on purpose. The app does not perform a complete electional-muhurta assessment, the fuller traditional work of choosing a moment for one occasion, which weighs many more factors. It does not replace a full panchang: no screen shows a choghadiya, hora, Rahu Kaal or other panchang table. It shows no score or rating, never marks any part of the day as a bad time, and does not predict outcomes. How it reads the day covers the rest of the calculation.

Common questions

Which is better, choghadiya or hora?

They are less rivals than two grains of one reading, built on the same seven grahas. The choghadiya gives a broad verdict on beginnings, the hora names the graha of the hour, and a cautious reading looks for a stretch where the two agree.

Can I use choghadiya and hora together?

Yes. Divide the daylight into eight parts and into twelve, keep the parts named Amrit, Shubh, Labh or Char, look inside them for the horas of Jupiter, Venus, Mercury or the Moon, and set aside the day's Rahu Kaal, Yamaganda and Gulika. A full panchang for your city lists both counts.

Do both counts restart at sunset?

The hora does not: its night horas continue the run that began at sunrise. The choghadiya starts the night from a new name set by the weekday, the name of the first night hora's graha.

Does the app show choghadiya or hora times?

No. It names the hora and the choghadiya of each window in its attribution and shows no table of either. A full panchang for your city lists both.
