What it is, and why advertisers care

Kerala's harvest festival and the state's largest retail moment by a wide margin. Thiru Onam is 12 September 2027, with the ten days before it being the actual shopping window. Onam advances paid to employees in Kerala put money in hand before the day.

What people are actually buying

Descriptions of the occasion, not promises about what will work. What works is an account question and this page has no data on your account.

  • Onam kodi, new clothes for the family
  • Onam sadya groceries
  • gold and jewellery
  • home appliance upgrades
  • Malayalam creative

Key dates and the run-up

Working back from 12 September 2027, a Sunday. These are suggestions, not measured figures, and the defaults behind them live in one file so they can be changed once rather than page by page.

  • Planning, 3 weeks
  • In market, 3 weeks before
  • The moment
  • After, 1 week

Suggested planning window, not a measured figure.

    Creative briefed and in production. Landing pages and offer pages built

  4. 2 weeks before 29 August 2027, Sunday
    Budgets raised on what is working. Weak creative cut
  5. The day itself 12 September 2027, Sunday
    The day itself. Watch delivery and spend pacing, not conversion rate
  6. After19 September 2027, Sunday
    Stop. Pull the numbers while the campaign is still fresh, and write down what you would change, because you will not remember in twelve months.

Who gains

Categories this moment reaches, and why. The reason is about the occasion, not about expected results.

Ad platform notes

Nothing here yet. A note only goes in this section when a platform documents something about this moment on its own help or business pages, with the link. Plenty of advice about seasonal bidding circulates without a platform ever having said it, and an empty section is more useful to you than a repeated claim.

For how the auctions themselves behave, the sourced version is in the algorithm pages linked at the bottom of this page.

Before you launch

Creative

  • One set of assets per placement, not one resized five ways. Current dimensions: meta ads, instagram, google ads.
  • Offer legible at thumbnail size, before anyone taps.
  • Dates on the creative if the offer ends, so nothing runs stale.
  • Language versions for the regions that call it Thiru Onam.

Measurement, and what breaks

  • Check conversion tracking before the spend ramps, not after.
  • Agree the attribution window now. Changing it mid-season makes the numbers unreadable.
  • Compare against the same weeks last year in your own account, not against a published benchmark.
  • The three that actually land mid-season: facebook ad rejected, facebook ad set not delivering, facebook pixel not firing.
  • Keep a note of what you changed and when, so next year starts from evidence.
