These are set by the companies that run them, usually a few days ahead. They are on the calendar because you still have to plan around them, and the weekly check moves each one into its month the day the date is announced.
Dates not announced
Amazon India's festive sale, and the event that runs against Flipkart's Big Billion Days.
2027 dates not announced. Amazon sets them and announces them a few days ahead, so no date is shown here. The weekly check looks for the announcement and upgrades this entry when it appears.
Early to mid October, timed to the run between Dussehra and Diwali. The 2026 edition, its thirteenth, began on 9 October with early access the day before.
Flipkart's festive sale, and one of the two events that define the Indian ecommerce year.
2027 dates not announced. Flipkart sets these dates and announces them a few days ahead, so this entry shows the typical window only. The weekly check upgrades it the day Flipkart announces.
The specs, the platform mechanics and the things that break, for the campaigns these dates are for.
the current dimensions, from each platform's own documentation
the disapprovals and delivery problems that actually land mid-season
official ranking signals, sourced, not recycled myths
plain definitions, with a position taken
A campaign planned in September and launched in October runs on whatever the platforms shipped in between.
This calendar carries 32 moments for India in 2027: 26 with a date confirmed by an official source, 4 expected but not yet confirmed, and 2 where the body or company that sets the date has not announced 2027 yet. It is not every observance in the country, only the ones that change what an advertiser should do.
From the body that sets them. Every moment on this page links to its own source, and the quoted line that was checked against that source is stored alongside it. The sources are re-fetched every month and every provisional date is re-checked every week. Nothing here is worked out from a calendar table on this site.
Because they are not. Retailers set their own sale dates and announce them days ahead, not a year out. Religious dates that depend on a moon sighting are confirmed locally close to the day. Showing you a guess in those cases would be worse than showing you the window, so the page shows the window.
A suggestion, not a measured figure, and every page says so where it appears. It works backwards from the date: when to agree the offer and budget, and when ads should be live. The defaults are set once per type of moment in one file, so they can be argued with and changed in one place rather than being different on every page.
Yes. The calendar file on this page imports into Google Calendar, Apple Calendar and Outlook as all-day events, so nothing lands a day out. The CSV has the same moments with the planning windows and the source URL for every row, which is the version to use if you are building a media plan.
No date on this calendar is calculated here. Every one is read off an official source and checked against it again every month. Where a 2027 date does not exist yet, the page says so rather than guessing.
