Guru Maharaj: Kṛṣṇa appeared at midnight and Balarāma appeared at noon. We fast for Nṛsiṁhadeva till sunset, since He appeared at that time. Because in Māyāpur we have Nṛsiṁha Deity, most of the devotees take anukalpa, it is optional, but on Janmāṣṭamī and Gaura Pūrṇimā we should take anukalpa prasād. On Gaura Pūrṇimā we fast till moon rise and on Janmāṣṭamī we fast till midnight. Because Lord Chaitanya appeared during the lunar eclipse.
