Ganda

Ganda is the tenth nityayoga, and its name means a knot, a danger, or an obstacle. It is one of the inauspicious yogas, regarded in the panchanga as unfavourable for beginning important undertakings. Reckoned like the others from the summed longitude of Sun and Moon divided into twenty-seven parts, it takes its place as the lights separate through the lunar month. The malefic yogas such as Ganda are avoided when an astrologer selects an auspicious moment, the tradition treating them as periods of entanglement and hindrance. These are the conventions of the calendar tradition, which assigns each of the twenty-seven yogas a settled favourable or unfavourable nature; the underlying reality is the combined motion of Sun and Moon.

The word ganda, a knot, has a documented secondary use in traditional Indian numerology and naming practice: children born under certain especially inauspicious combinations of tithi, nakshatra, and yoga, this one among them, are traditionally described as born in ganda mool or a related inauspicious condition, and some regional customs prescribe a specific pacifying ritual, a shanti rite, performed shortly after birth to counteract the association before the child is formally named. This is a separate, birth-specific application of the same inauspicious classification described in general terms above, applied to the individual nativity rather than to the choice of a muhurta for an undertaking.

The yoga is the limb of the panchanga that has no counterpart in the sky. Nothing about the day looks different when one ends and the next begins. Where the tithi measures the Moon's separation FROM the Sun, the yoga measures the two longitudes ADDED together, and cuts the resulting circle into twenty seven equal arcs of thirteen degrees twenty minutes. Ganda is the arc from 120 degrees 00 minutes to 133 degrees 20 minutes of that sum. The sum climbs at roughly fourteen degrees ten minutes a day, so a yoga runs about twenty two and a half hours on average, a little shorter than a tithi, and like a tithi it can be skipped between two sunrises or carried across two of them.

The twenty seven arcs are the same width as the twenty seven nakshatras, and Ganda is the tenth arc of the grid in both schemes, which is why the two are often tabulated side by side. They are not the same thing and share nothing but their arithmetic: a nakshatra is a segment of the sky the Moon is physically standing in, while a yoga is a number derived from two positions and belongs to no part of the sky at all. Reading a yoga as a star group is the commonest confusion the term invites, and the shared name of the tenth position, Magha, is where it usually starts.

Ganda sits among the nine yogas classed as unfavourable. Nine of twenty seven is a third of the cycle, so an inauspicious yoga is a common event rather than a rare one, and the muhurta literature treats it accordingly: it weighs against a time without ruling it out, and is routinely overridden where the tithi, the nakshatra and the weekday agree.
