TASMAC dry days: every date the shops stay shut
Four dates repeat every year, and in practice there are always more — 2026 had eight. Miss one and you have made a wasted trip. Here are the dates you can plan around, how the election ones work, and what our own stock data says happens the day after. For every date this year, see the complete 2026 list.
The four you can plan around
These four are dry across the whole of Tamil Nadu, every year, and they do not move. They are the floor, not the total — declared dry days (memorial days, religious observances) and election closures are added on top, and 2026 had eight in all. Every TASMAC shop stays shut for the full day — not reduced hours, closed.
| Date | Occasion | Scope |
|---|---|---|
| 26 January | Republic Day | Statewide · national |
| 1 May | May Day | Statewide · state |
| 15 August | Independence Day | Statewide · national |
| 2 October | Gandhi Jayanti | Statewide · national |
So the next dry day is Friday 2 October 2026, Gandhi Jayanti. After that, 26 January 2027.
Election dry days are the ones that catch people out
Beyond the fixed four, the state declares dry days around polling — typically the 48 hours before voting closes, plus counting day. These are the ones people miss, because they are announced separately and can be district-specific: shops shut in the districts going to the polls while the rest of Tamil Nadu trades normally. There is no fixed annual pattern to them; they follow the election calendar.
Rule of thumb: the four national and state dry days are predictable and statewide. Election dry days are announced, local, and worth checking the day before.
What our data shows: a dry day does not reduce drinking, it moves it
This is the part we did not expect. We track stock movement across every TASMAC shop in Tamil Nadu, several times a day. On 15 August 2026, Independence Day, our count across all 38 districts was exactly what it should have been on a dry day: zero bottles. Nothing moved anywhere in the state.
Then look at the next morning. 16 August was the single largest day in our entire dataset — about 12.1 million bottles statewide, against a typical trading day of roughly 7.6 million. That is around 59% above a normal day, and it is not spread out over the following week; it lands almost entirely in the first day back.
We saw the same signature again on 26 August 2026, when statewide movement fell to zero and our system flagged the closure automatically — the day after came in around 8.8 million, again above the 7.6 million baseline. The pattern is consistent: demand does not disappear on a dry day, it is deferred to the next morning, and the queues the following day are correspondingly worse.
What to do about it
Two practical consequences. If you plan to drink on a dry day, buy the day before, not the morning of — and expect that everyone else has had the same idea, because the day before a dry day also runs above baseline. If you are shopping the day after, go early: the surge lands in the first session back, and popular products are the first to run out.
Stock depth matters more than usual on those two days. A shop that is normally reliable for your brand can be cleared out by mid-evening on a post-dry-day surge, which is precisely when a live stock count is worth having in your pocket.
How Sarakku handles dry days
The app knows the fixed dates and marks them ahead of time, so the map tells you the shops are shut before you walk. It also detects unexpected statewide closures from the stock data itself — the 26 August signature above was flagged automatically, without anyone filing a notice. Election dry days are added as they are announced.
Four dates a year are certain. The rest is worth a ten-second check before you leave the house.
