Inauspicious Nitya Yogas gathers the nine of the panchanga's twenty seven daily yogas classed as unfavourable, computed the same way as the eighteen auspicious yogas: from the combined longitudes of the Sun and the Moon, divided into twenty seven spans of thirteen degrees twenty minutes, a new yoga completing each time the two luminaries together advance by one such span.
Most name the harm they warn against directly. Vishkambha, a support and also an obstacle, opens the full cycle and is generally avoided for delicate beginnings, though some authorities hold only its opening portion unfavourable. Atiganda, a great knot or great danger, calls for propitiatory worship rather than simple avoidance. Shula, a piercing pain, is avoided for surgery and sharp tools. Ganda, a knot or obstruction, is avoided on the reasoning that it knots up whatever is started under it. Vyaghata, a striking or collision, is avoided for confrontations and contracts. Parigha, the iron bar set across a gate, is a yoga of blockage, though authorities differ on whether only its first half is unfavourable.
Two are treated as more than merely inauspicious. Vajra, named for Indra's thunderbolt weapon despite that powerful association, is judged too hard and confrontational for peaceable beginnings. Vyatipata and Vaidhriti, calamity and poor support, form a pair the tradition treats as gravely inauspicious rather than simply unfavourable, avoided outright for auspicious work and marked in the almanacs for expiatory observance. Vaidhriti closes the twenty seven day cycle, which then returns again to Vishkambha.
