Yoga and Karaṇa: The Two Panchāṅga Limbs Nobody Explains

Open any pañcāṅga and you will find five columns. Most people can say something about three of them. Tithi is the lunar day, vāra is the weekday, nakṣatra is the lunar mansion. Then the eye reaches the fourth and fifth columns, sees something like Siddhi and Taitila, and slides past.

Those two columns are the yoga and the karaṇa. They are the least explained limbs of the pañcāṅga, and the reason is not that they are complicated.

The reason is that almost nobody writing about them online has bothered to state the arithmetic, so the explanations that exist are lists of names with adjectives attached. A list of names is useless. The arithmetic takes two paragraphs and then the whole thing sits still in your head.

I am an engineer rather than a professional astrologer, and what follows is the classical definition and the computation behind it, stated plainly. What you do with a yoga or a karaṇa in your own life is your call.

The yoga is the only limb built from a sum

Here is the structural fact that makes the pañcāṅga click, and I have almost never seen it written down.

Four of the five limbs come from the Sun and Moon. The tithi is the Moon’s longitude minus the Sun’s longitude, sliced into thirty. The karaṇa is the same difference sliced into sixty. The nakṣatra is the Moon’s longitude on its own, sliced into twenty seven. And the yoga is the Moon’s longitude plus the Sun’s longitude, sliced into twenty seven.

So the yoga is the only limb in the entire system that is built by adding two longitudes together. Everything else subtracts, or uses one body alone.

Once you see that, the yoga stops being a mystery name in a column and becomes an obvious fifth measurement: if you are going to describe the relationship between two moving bodies, you measure their separation and you measure their combined position, and those are two different quantities.

The practical consequence follows immediately. The sum advances at the Moon’s mean daily motion plus the Sun’s, roughly 13.18 degrees plus 0.99 degrees, which is about 14.17 degrees a day. Each yoga spans 13 degrees 20 minutes.

So a yoga lasts about 22 hours 36 minutes on average, while a nakṣatra lasts about 24 hours 20 minutes on average. The yoga runs slightly faster than the nakṣatra, always. That is why the yoga column changes over a little earlier each day relative to the nakṣatra column, and it is a good sanity check that the pañcāṅga you are holding was computed rather than copied.

I have laid out how the tithi behaves in the same way in the piece on tithi length, and the five limbs together in the pañcāṅga overview.

The twenty seven yogas, and the nine that muhūrta avoids

In order: Viṣkambha, Prīti, Āyuṣmān, Saubhāgya, Śobhana, Atigaṇḍa, Sukarmā, Dhṛti, Śūla, Gaṇḍa, Vṛddhi, Dhruva, Vyāghāta, Harṣaṇa, Vajra, Siddhi, Vyatīpāta, Varīyān, Parigha, Śiva, Siddha, Sādhya, Śubha, Śukla, Brahma, Indra, Vaidhṛti.

Muhūrta texts single out nine of these as unsuitable for beginning something that you want to last: Viṣkambha, Atigaṇḍa, Śūla, Gaṇḍa, Vyāghāta, Vajra, Vyatīpāta, Parigha and Vaidhṛti.

Of those nine, Vyatīpāta and Vaidhṛti carry the most weight, because both mark a configuration where the Sun and Moon have equal declination on opposite sides of the celestial equator. That is a real astronomical event with a definition, and it is the reason those two yogas are treated more seriously than the rest of the list.

A calm way to hold this: a difficult yoga is a statement about the quality of a window, and windows are things you can choose. It says nothing about a person, and there is nothing to fix. Anyone selling you a remedy for having been born under Vyatīpāta is selling you something the texts do not ask for.

A karaṇa is half a tithi, and there are sixty in a lunar month

The karaṇa is the simplest object in the pañcāṅga once the tithi is clear. A tithi is 12 degrees of Moon minus Sun separation. A karaṇa is 6 degrees of the same separation. Half a tithi, exactly.

Thirty tithis in a lunar month therefore give sixty karaṇas in a lunar month. Every tithi contains two of them, a first half and a second half.

What makes the karaṇa interesting is that those sixty slots are filled by only eleven names, and the filling rule is not a simple repeat.

Seven karaṇas that move and four that stay put

Seven karaṇas are called chara, moving: Bava, Bālava, Kaulava, Taitila, Gara, Vaṇija and Viṣṭi. These seven cycle in that order, over and over, eight full times, which accounts for fifty six of the sixty slots.

Four are called sthira, fixed, and each occurs exactly once per lunar month, always in the same place: Kiṁstughna in the first half of Śukla Pratipadā, then Śakuni in the second half of Kṛṣṇa Chaturdaśī, Catuṣpāda in the first half of Amāvāsyā and Nāga in the second half of Amāvāsyā.

Fifty six plus four is sixty. The whole month is accounted for with no remainder, which is the kind of closure that tells you a scheme was designed rather than accumulated. Notice also that the four fixed karaṇas cluster at the two ends of the lunar month, bracketing the new moon. The cycle of seven runs uninterrupted through everything in between.

Viṣṭi karaṇa is Bhadrā, and this is the Raksha Bandhan question

Here is the connection that almost no listing makes explicit. The seventh moving karaṇa, Viṣṭi, is the same thing as Bhadrā.

Every year there is a public argument about the correct window for tying the rākhī, and the argument is entirely about Bhadrā. It is the same object sitting in the fifth column of the pañcāṅga, under a different name, appearing eight times a month like clockwork.

If you have ever wondered why the rākhī timing question exists at all while nobody argues about most other festivals, that is why: the ritual is tied to Śrāvaṇa Śukla Pūrṇimā, and Bhadrā lands on Pūrṇimā often enough to matter.

I have written out the 2027 timing in the Raksha Bandhan piece, which uses the verified festival date from the site’s own engine.

The rarely quoted part is that classical muhūrta does not treat Bhadrā as uniformly obstructive. There is a rule about where Bhadrā is residing, determined by the rāśi the Moon occupies.

When Bhadrā is said to reside in svarga or in pātāla, its effect on earthly beginnings is treated as far lighter than when it resides on the earth. Most modern calendars flatten this into a single warning band and drop the residence rule entirely.

Per Muhūrta Chintāmaṇi (svarge bhadrā śubhaṁ kuryāt pātāle ca dhanāgamaḥ, mṛtyuloka-sthitā bhadrā sarva-kārya-vināśinī), the grouping runs by the Moon’s rāśi: Aries, Taurus, Gemini or Scorpio places Bhadrā in svarga, favourable; Virgo, Libra, Sagittarius or Capricorn places her in pātāla, also favourable; Cancer, Leo, Aquarius or Pisces places her on martyaloka, the earth, and that is the one placement the texts actually ask you to avoid starting something in.

The misreading: this yoga is not the yoga you have heard of

This is the single most common confusion, and it is a naming accident.

When somebody says “you have Gaja Kesari yoga in your chart,” they are talking about a combination of planets in a birth chart, a permanent feature of that chart, described in the yoga chapters of BPHS.

When a pañcāṅga says “today’s yoga is Sukarmā,” it is talking about the Sun plus Moon sum on that particular day, a quantity that changes every twenty two and a half hours and applies to the entire planet at once.

These are two unrelated objects that share an English transliteration. The pañcāṅga kind is properly called the nitya yoga, the daily yoga, precisely to keep it separate. Nobody has Vyatīpāta yoga as a chart feature the way they have Gaja Kesari. They were simply born during a Vyatīpāta window, along with everyone else born on Earth in that same twenty two hours.

I bring this up because I have seen readers frightened by the adjective attached to a nitya yoga in a birth report, believing it described something personal and permanent. It does not.

How to actually use these two limbs

For a birth chart, the yoga and the karaṇa are minor. They are two of the five things that describe the sky’s condition on a date, and the chart already encodes the same Sun and Moon positions with far more resolution. If a reading leans hard on your birth karaṇa, it has run out of better material.

For muhūrta, choosing a moment for something, they matter more. The classical practice is to check the tithi, the vāra, the nakṣatra and the lagna first, and treat the yoga and karaṇa as filters that can rule a window out rather than reasons to pick it.

Bhadrā rules out a window. Vyatīpāta rules out a window. A clean yoga on its own does not make a bad muhūrta good.

And the honest caveat: a well chosen muhūrta is a preference expressed in time, and it makes no promise about how anything turns out. The texts describe what conditions are traditionally considered supportive. They do not offer a guarantee, and neither will I.
