Flipkart’s Big Billion Days sale is usually held once a year around late September to early October, and upcoming info is only confirmed close to the event.

Latest expected dates

  • For 2025, several deal-tracking sites report the sale is expected around late September to early October 2025 (for example, 27 September–5 October in some listings), but note that these are expected/announced schedules and can shift slightly.
  • For 2026 , some sale calendars list Flipkart Big Billion Days Sale starting around 23 September 2026 and running into early October.

Flipkart itself typically announces the official dates a few weeks before the sale on its app, website, and social channels, so always double‑check there as the event approaches for the exact start and end times.

Tip: Plus members often get early access (usually from midnight a day earlier than regular users), so if you have Flipkart Plus, you may see deals slightly before the public dates.

TL;DR:
The Big Billion Days sale happens once a year, usually in the last week of September spilling into early October , with official dates confirmed by Flipkart shortly before the festival season each year.
