Auspicious for all good work: marriage, charity, the consecration of images, and the parana, the breaking of the Ekadashi fast. Bhadra class.
Meaning
Dwadashi is the twelfth tithi, and it belongs to Vishnu as the day on which the Ekadashi fast is broken. The pair of Ekadashi and Dwadashi is the classical unit of the fortnight's observance, and the tithi is read as benefic for anything that follows a restraint.
