The Five Limbs of the Day (the Panchang)

In the last chapter we looked up at the stars and learned how the tradition mapped them. Now let us bring that sky down into the home. For the sky is not only to be studied. It is also to be lived by.

Picture a small book kept in many Hindu homes, even today. It is called the Panchang. From it a family learns when a festival falls, when a fast begins, which day is fit for a journey or a wedding. It is the old almanac of sacred time.

The word itself tells you how it works. Pancha means "five." Anga means "a limb." So Panchang means "the five limbs." To name a day truly, the tradition reads five things in the sky at once. Let us meet them one by one.

The first limb is the tithi. This is the phase of the moon. As the moon grows from new to full and shrinks back again, that journey is cut into thirty steps. Each step is one tithi. So the tithi tells you exactly how full the moon is on this day. Many fasts and festivals are fixed to a tithi, not to a date on a wall calendar.

The second limb is the vara. This is the simplest one. It is the ordinary weekday, the seven-day week you already know. Each day belongs to one of the sky-lights — Sunday to the sun, Monday to the moon, and so on. The seven-day week itself is very old and is shared across many lands.

The third limb is the nakshatra. We met this word among the stars. The moon travels along a fixed path among the stars, and that path is divided into twenty-seven star-houses, the nakshatras. The nakshatra tells you which star-house the moon is resting in tonight. A child's birth-star is its nakshatra.

The fourth limb is the yoga. This one is a little finer. It comes from adding together where the sun stands and where the moon stands, and reading the sum. There are twenty-seven of these yogas, each with its own name and feeling. You do not need the arithmetic. Just hold that the yoga measures the sun and moon together.

The fifth limb is the karana. This is the easiest of all once you know the tithi. A karana is simply half of a tithi. Since each tithi is one step of the moon's phase, cutting it in two gives the karana. It is the smallest of the five limbs, used for choosing fit hours within a day.

So there they are, the five limbs. Tithi, the moon's phase. Vara, the weekday. Nakshatra, the moon's star-house. Yoga, the sun and moon summed. Karana, the half-tithi. Read all five, and a day is no longer a blank square on a calendar. It has a face. It has a place in the turning of the heavens.

Where did these rules come from? The watching began long ago, with the Vedic priests who needed to time their fire-rites by the moon and the stars. Over many centuries the watching grew into a careful science. The working methods were gathered in the classical star-manuals, among them a famous text called the Surya Siddhanta, the "sun-treatise," which set out how to compute the moon, the sun, and the turning year.^[1]

Hold the word Panchang gently, for it will return. In the next sections we will see how these five limbs let the tradition keep two clocks at once, the moon's and the sun's, and how, from them, the day of every great festival is found.
