Panchanga Suddhi for Muhurtha

A Panchanga consists of tithi, vara, nakshatra. yoga and karana. All these must be
auspicious. In regard to lunar days, the 4th, 6th, 8th, 12th and 14th, full
and new moon days should be avoided. In regard to vara, Thursday and
Friday are held to be suitable for all works. Tuesday, is to be generally
avoided except when it happens to be the 10th, 12th or 16th day of the
child's birth when the child's Namakarana (baptising or giving name)
may be performed. Of the several Nakshatras, Bharani and Krittika
should be avoided for all auspicious works as these two are said to be
presided over by the god of death (Yama) and the god of fire (Agni)
respectively. In urgent cases if the Lagna could be fortified, the dosha
due to nakshatra may get neutralised. The last parts of Aslesha,
Jyeshta and Revati should also be avoided. Coming to the Yoga (vide
page 12) the 6th (Atiganda). 9th (Soola). 10th (Ganda), 17th (Vyatipata)
and 27th (Vydhruti) have deleterious effects upon events which are
started or commenced under them. - The Karana chosen must be
appropriate to the election in view. Thus Bava is auspicious for starting
works of permanent importance while Thaithula is propitious for
marriage. Bhadra is unfit for any good work but is eminently suitable for
violent and cruel deeds. For getting initiation into kshudra mantras
Sakuni Havana is propitious.

Therefore, Panchanga Suddhi means a good lunar day, a beneficial
weekday, an auspicious constellation, a good yoga and a fertilising
Karana.
