Krishna Janmashtami celebrates the birth of Shri Krishna, which tradition places at midnight on the Ashtami of the dark fortnight, under Rohini nakshatra. It falls on Bhadrapada Krishna Ashtami in the Purnimanta calendar, which is the same day as Shravana Krishna Ashtami in the Amanta calendar (see Amanta and Purnimanta).

It is common to see Janmashtami listed on two consecutive days, one marked Smarta and one Vaishnava. Both follow long-standing traditions; they simply give weight to different factors.

The Smarta rule: Ashtami at Nishita

The Smarta approach centres on the moment of birth. Janmashtami is observed on the night when Ashtami prevails at Nishita. Nishita is the 8th of the 15 muhurtas of the night (measured from sunset to the next sunrise), so it falls around local midnight. If Ashtami touches Nishita on two nights, the night with the larger overlap is chosen. The midnight puja, with abhisheka of Bal Gopal, is performed within this Nishita window.

This is the rule used on this platform.

The Vaishnava practice: udaya Ashtami and Rohini

Many Vaishnava communities, including ISKCON, place greater emphasis on:

  • Udaya Ashtami: Ashtami prevailing at sunrise of the observance day, and
  • Rohini nakshatra, the birth star of Krishna, and its presence on that day.

Because Ashtami that reaches midnight on one night often continues past the next sunrise, the Vaishnava date is frequently the day after the Smarta date. In some years both methods agree on the same day.

Fasting and Parana

Devotees usually fast until the midnight puja. Parana conventions vary: some break the fast after Nishita on the same night, while others wait until the next day, after sunrise, and some traditions consider when Ashtami and Rohini end. Traditions may vary by region, sampradaya and Panchang convention, so follow your family or temple practice.

In Maharashtra and some other regions, the day after Janmashtami is celebrated with Dahi Handi, and temples across India hold night-long kirtan.
