Question: Why Janmāṣṭamī is on both days 11th or 12th, nobody is able answer properly whether we have to fast on 11th or 12th. How can we easily convince them that why actually Janmāṣṭamī is on 12th?

Guru Maharaj:  So we have our Vaiṣṇava opinion regarding the fasting. Sometimes if the fasting day is touched by the daśamī tithi, it is not auspicious to follow.  Sometimes the smārtha calculations, it gets clashed with the Vaiṣṇava opinion.
