Why different observance dates can occur
Janmashtami is tied to Krishna Paksha Ashtami and the traditional Rohini association. Smarta and Vaishnava calendars apply different rules for tithi, sunrise, overlap and the avoidance of preceding-tithi influence. Vaishnava traditions are themselves diverse: it is inaccurate to say all insist on Rohini overlap or always celebrate one day later. Differences arise in particular years, not automatically every year.
Which 2026 date should you follow?
The Mumbai calendar lists Janmashtami on 4 September 2026 and Dahi Handi on 5 September. Source: Drik Panchang’s Mumbai calendar. Follow the published calendar of your temple or family tradition, especially outside India. Dahi Handi’s separate date is not itself proof of a Smarta–Vaishnava split.
Keep the observance and parana rule consistent
Ask your temple which date, night puja and parana rule go together. Do not combine one calendar’s fast date with another’s breaking time. If you have no established custom, ask a local officiant rather than assuming all householders must use the same tradition. See the parana guide.
