The Five Limbs of a Hindu Day > Panchang means five limbs. Four of them are functions of just two numbers, and the fifth is the weekday. Here is what each one measures. # What Is Panchang? The Five Limbs of a Hindu Day What is panchang, in one line: it is the set of five quantities that describe a given date at a given place, and the word itself says so. *Pancha* is five, *anga* is limb. The five are tithi, vara, nakshatra, yoga and karana, and between them they answer what the Moon is doing, what the Sun is doing, and which day of the week it is according to sunrise rather than midnight. Most explanations stop at that list. The part worth knowing is that four of the five limbs are not five separate observations at all. They are four different arithmetic operations on exactly two numbers. ## What is panchang built from? The five limbs Take the Sun's sidereal longitude and the Moon's sidereal longitude for the moment you care about. That is all the raw material there is: - **Nakshatra** is the Moon's longitude divided into 27 arcs of 13°20'. It says where the Moon is sitting. - **Tithi** is the gap between them, Moon minus Sun, divided into 30 steps of 12°. It says how far the Moon has pulled ahead since the new Moon. - **Yoga** is their sum, Moon plus Sun, divided into 27 arcs of 13°20'. Nothing else in the panchang adds the two longitudes. - **Karana** is half a tithi, the same gap divided into steps of 6°, so two of them fill every tithi. - **Vara** is the weekday, and it is the odd one out. Vara is not an angle. You cannot compute it from a planetary position, because it is a position in a repeating cycle of seven that has nothing to do with where anything is in the sky today. Where that cycle came from is a genuinely good story, and it is told in full in [vara in panchang](https://mahadasha.com/vara-in-panchang) . ## Four limbs from two numbers Write the four angular limbs next to each other and the structure is hard to miss. If M is the Moon's longitude and S is the Sun's: - nakshatra = M / 13°20' - tithi = (M − S) / 12° - yoga = (M + S) / 13°20' - karana = (M − S) / 6° One uses the Moon alone. One subtracts. One adds. One subtracts and halves the step. That is the entire system, and it explains something that otherwise looks arbitrary: why the five limbs run for such different lengths of time. ## How long each limb actually lasts Nobody tells you this, and it changes how you read a panchang. None of the limbs lasts a day. Here is what they measured across the whole of 2026, taken from the same ephemeris the site's calculator uses, with every boundary crossing solved rather than estimated: - Nakshatra: 24h 14m on average, running between 20h 54m and 27h 08m. - Tithi: 23h 35m on average, between 20h 04m and 26h 43m. - Yoga: 22h 34m on average, between 19h 36m and 24h 59m. - Karana: 11h 47m on average, between 10h 02m and 13h 22m. The ordering is not random and it is not tradition. It falls out of the rates. The Moon gains about 13.18° a day, so a 13°20' nakshatra takes a shade over a day to cross. The gap between Moon and Sun opens more slowly, about 12.19° a day, because the Sun is moving forward too. And the sum of the two climbs fastest of all, about 14.17° a day, since both bodies push it in the same direction. Fastest rate over the same 13°20' step means the shortest limb, which is why yoga is always the one that turns over soonest. ## Why a panchang day begins at sunrise A panchang day runs sunrise to sunrise. That is not a rounding convention, it is the whole basis of the reckoning, and it has a consequence people trip over constantly: the five limbs quoted for a date are the values *at that sunrise*, not values that hold all day. Tithi, nakshatra, yoga and karana are all sliding continuously, and each one has an end time. A panchang that says "Saptami" means Saptami was running when the Sun came up, and it may well have given way by mid-evening. It also means the weekday changes several hours after your phone says it does. If something is prescribed for a Thursday, the Thursday in question started at Thursday's sunrise and ends at Friday's, so the small hours of Friday morning still belong to Thursday. ## The windows layered on top Once you have the five limbs and the sunrise and sunset times, a second layer becomes available: the parts of the day that are held to be favourable or best avoided. These are not extra limbs. They are subdivisions of the daylight. The daylight gets split eight ways for [Rahu Kaal timing](https://mahadasha.com/rahu-kaal-timing) , [Yamaganda Kaal](https://mahadasha.com/yamaganda-kaal) and [Gulika Kaal](https://mahadasha.com/gulika-kaal) , and eight ways again on a different footing for [Choghadiya muhurat](https://mahadasha.com/choghadiya-muhurat) . It gets split fifteen ways for the muhurtas, of which the middle one is [Abhijit muhurat](https://mahadasha.com/abhijit-muhurat) . And it gets split twelve ways for the planetary hours covered in [hora timing in astrology](https://mahadasha.com/hora-timing-in-astrology) . Different divisors, same daylight. Two of those windows turn out to be derivable rather than tabulated, which surprised us when we checked: Gulika is always Saturn's eighth part of the day and Yamaganda is always Jupiter's. Rahu Kaal, the one everybody actually observes, is the exception, and the reason is simple enough that it is worth saying here. Rahu owns no planetary hour, so there is no lord to look for. ## Reading a real day, start to finish Take 5 August 2026 at Delhi. Sunrise at 05:45:50, sunset at 19:08:12, so the daylight span is 13 hours 22 minutes. The five limbs at that sunrise: - Tithi: Saptami of the Krishna paksha, ending 20:42:50. - Vara: Wednesday. - Nakshatra: Ashwini, second pada, ending 21:18:22. - Yoga: Shula, ending 17:29:02. - Karana: Vishti, ending 09:26:59. Read the end times and the day organises itself. Vishti karana, the one called Bhadra, clears before half past nine in the morning. Yoga turns over at half past five. The tithi and the nakshatra both run into the evening. Nothing here holds for twenty-four hours, and a reading that ignores the end times is describing a day that does not exist. Layer the windows on and it sharpens further. Rahu Kaal on that Wednesday runs 12:27 to 14:07, Gulika 10:46 to 12:27, Yamaganda 07:26 to 09:06. Abhijit sits 12:00 to 12:53. And here is the catch that makes Wednesday different from every other day: on Wednesdays the inauspicious Dur Muhurtam is the same window as Abhijit, exactly. Same start, same end. That is the arithmetic behind the old instruction not to use Abhijit on a Wednesday, and it is the only day of the seven where the two coincide and nothing else does. ## What a panchang is not It is not a horoscope. Nothing in the five limbs is personal to you, and none of it needs a birth time. A panchang describes a *day* at a *place*, which is why two people in the same city share one, and why someone in another timezone has a different one for the same calendar date. Sunrise moves, so everything anchored to sunrise moves with it. It is also not a verdict. The limbs are inputs. Choosing a moment to begin something means weighing several of them together and accepting that they will sometimes disagree, which is the subject of [auspicious and inauspicious days](https://mahadasha.com/auspicious-and-inauspicious-days) . ## Frequently asked questions ### What is panchang used for in practice? Two things, mostly. Fixing the date of a festival, which is defined by tithi and month rather than by the Gregorian calendar, and choosing a time to start something that matters. The second use is what the muhurat tools are for. ### Why five limbs and not four, or six? Because the five cover the two bodies in every combination that yields a usable period: the Moon alone, the difference, the sum, half the difference, and the weekday that carries the ritual calendar. Adding a sixth would either repeat one of these or produce a period too short to plan around. ### Does a panchang need my birth details? No. It needs a date, a latitude and a longitude. Every quantity in it is shared by everyone standing in the same city on the same day. ### Why does my panchang differ from someone else's? Usually one of three reasons. A different ayanamsa, which shifts every sidereal longitude and therefore every limb. A different location, which moves sunrise and therefore moves the whole day. Or the purnimanta versus amanta month convention, which changes the month name without changing the tithi at all. Run your own date and city through the [panchang calculator](https://mahadasha.com/panchang-calculator) and it will return all five limbs with their end times, plus every window described above. If you would rather start from the Moon's own division of the sky, the [27 nakshatras in Vedic astrology](https://mahadasha.com/27-nakshatras-in-vedic-astrology) covers that limb star by star.
