Janmashtami (ISKCON)

Devotees, who observe fast on Janmashtami, should have only single meal a day before Janmashtami. On fasting day, devotees take Sankalpa to observe a day long fast and to break it on the next day when both Rohini Nakshatra and Ashtami Tithi are over. Some devotees break the fast when either Rohini Nakshatra or Ashtami Tithi is over. Sankalpa is taken after finishing morning rituals and the day long fasting begins with Sankalpa.

The time to perform Krishna Puja is during Nishita Kala which is the midnight as per Vedic time-keeping. Devotees perform detailed ritualistic Puja during midnight and it involves all sixteen steps which are part of Shodashopachara (षोडशोपचार) Puja Vidhi.

Fasting Rules on Krishna Janmashtami

No grains should be consumed during Janmashtami fasting until the fast is broken on next day after Sunrise. All rules followed during Ekadashi fasting should be followed during Janmashtami fasting also.

Parana which means breaking the fast should be done at an appropriate time. For Krishna Janmashtami fasting, Parana is done on next day after Sunrise when Ashtami Tithi and Rohini Nakshatra are over. If Ashtami Tithi and Rohini Nakshatra don't get over before Sunset then fast can be broken during day time when either Ashtami Tithi or Rohini Nakshatra is over. When neither Ashtami Tithi nor Rohini Nakshatra is over before Sunset or even Hindu Midnight (also known as Nishita Time) one should wait to get them over before breaking the fast.

Depending on end timing of Ashtami Tithi and Rohini Nakshatra fasting on Krishna Janmashtami might continue for two complete days. Devotees who are not able to follow two days fasting might break the fast on next day after Sunrise. It has been suggested by Hindu religious text Dharmasindhu.

Krishna Janmashtami is also known as Krishnashtami, Gokulashtami, Ashtami Rohini, Srikrishna Jayanti and Sree Jayanthi.
