See what are the Fasting Rules on Krishna Janamashtmi
All the rules that are followed during Ekadashi fasting should also be followed during Janmashtami fasting. You cannot consume grains during Janamashtmi fasting until the fast is broken on next day after sunrise.
Parana which means breaking the fast is done at an appropriate time as suggested by the Pandits. During Krishna Janamashtmi fasting, Parana is done on the next day after sunrise when Ashtami Tithi and Rohini Nakshatra are over. If sometime the next day, 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. Sometimes it happens that neither Ashtami Tithi nor Rohini Nakshatra is over before Sunset or even Hindu Midnight ,then one should wait to get them over before breaking the fast.
Sometimes Krishna Janamashtmi fasting might continue for two complete days depending on the end timing of Ashtami Tithi and Rohini Nakshatra. Devotees who are not able to follow two days fasting, break their fasting the next day after sunrise and it has been suggested by Hindu religious text Dharmasindhu.
About Two Krishna Janamashtmi Dates
We have seen that most of the time, Krishna Janamashtmi is listed in two consecutive days where the first one is for Smarta Sampradaya and the other one is for Vaishanava Sampradaya. The Vaishanava Sampradaya date comes after the Smarta Sampradaya. When Janamashtmi falls on a single date, it means that both Sampradayas have observed Janamashtmi on the same date.
ISKON Followers have unity in choosing the date for Janamashtami which basically depends on the institution of ISKON.ISKON stands for International Society for Krishna Consciousness and is founded on the principles of Vaishnava traditions. Followers of ISKON are the followers of Vaishnavism. They celebrate Janmashtami on the day chosen by ISKCON. Smarta followers do not follow ISCON date for the Janamashtmi fasting. ISKCON date to observe Janmashtami is commonly followed in Braj region.
Generally, People who do not believe in Vaishnavism are followers of Smartism. Dharmasindhu and Nirnaysindhu are the two Hindu religious texts which have well defined rules to fix Janmashtami Day and if you are not the follower of Vaishnava Sampradaya then you should follow those rules. We can see during Ekadashi fasting , rules for Smarta and Vaishnava communities are different. However there is more awareness about different Ekadashi rules followed by Vaishnava Sectarian. Like Ekadashi, Vaishnava fasting day for Janmashtami and Rama Navami might be one day later than Smarta fasting day.
The main differences in the two different dates are: -
People who follow Vaishnavism give preference to Ashtami Tithi and Rohini Nakshatra and they never observe Janmashtami on Saptami Tithi. According to Vashnava Rules Janmashtami day always fall on Ashtami or Navami Tithi on Hindu calendar while Janmashtami day according to Smarta rules always falls on Saptami or Ashtami Tithi on Hindu calendar.
