Valve has dated 17 Steam events between 16 November 2026 and 8 July 2027: three seasonal sales, two Next Fests and 12 themed fests. For a launch date, the cutoff matters most: a game must be out at least 30 days before a sale starts to discount in it. For the three seasonal sales, those cutoffs are 17 November 2026, 16 February 2027 and 25 May 2027. On 12 November 2026, the Winter cutoff is five days away.
What are the Steam sale dates for 2027?
Every date below comes from Valve’s Steamworks pages, read on 4 November 2026 and checked again on 12 November 2026. Valve first published the 2027 schedule in a Steamworks announcement on 15 July 2026, and its Upcoming Steam Events page carries the same list. The cutoff column is our arithmetic: the start date minus 30 days, the length of Steam’s release cooldown.
| Event | Dates | Type | Released by (to discount in it) | Note for a launch |
|---|---|---|---|---|
| Auto-Battler RPG Fest | 16 to 23 Nov 2026 | Themed fest | 17 Oct 2026 (passed) | Theme fits few games |
| Black Friday highlight | November 2026 | Special Offers hub | Not dated | Still undated on 12 Nov 2026 |
| Winter Sale | 17 Dec 2026 to 4 Jan 2027 | Seasonal sale | 17 Nov 2026 | Starts at 10am Pacific |
| Desktop Companion Fest | 14 to 18 Jan 2027 | Themed fest | 15 Dec 2026 | |
| Shop Keeper Fest | 25 Jan to 1 Feb | Themed fest | 26 Dec 2026 | |
| Sheep Fest | 4 to 8 Feb | Themed fest | 5 Jan | |
| Couch Co-Op Fest | 8 to 15 Feb | Themed fest | 9 Jan | Local co-op required |
| Next Fest | 22 Feb to 1 Mar | Next Fest | Must release after 1 Mar | Registration closes 10 Jan |
| Rhythm Fest | 8 to 15 Mar | Themed fest | 6 Feb | |
| Spring Sale | 18 to 25 Mar | Seasonal sale | 16 Feb | |
| Dinos vs. Robots Fest | 29 Mar to 5 Apr | Themed fest | 27 Feb | |
| Racing Fest | 12 to 19 Apr | Themed fest | 13 Mar | |
| Witch Fest | 22 to 26 Apr | Themed fest | 23 Mar | |
| Fighting Fest | 26 Apr to 3 May | Themed fest | 27 Mar | Fighting games in the FGC sense |
| Real-Time Strategy Fest | 10 to 17 May | Themed fest | 10 Apr | |
| Mountaineering Fest | 31 May to 3 Jun | Themed fest | 1 May | |
| Next Fest | 14 to 21 Jun | Next Fest | Must release after 21 Jun | |
| Summer Sale | 24 Jun to 8 Jul | Seasonal sale | 25 May |
Two gaps remain. The Autumn Sale 2027 is listed as TBD, and nothing after 8 July 2027 has a date yet. For reference only, the 2026 Autumn Sale ran 1 to 8 October and the October 2026 Next Fest ran 19 to 26 October. Some fest cutoffs fall on a Saturday, and the Steamworks date picker hides weekends, so in practice the last pickable day is the Friday before.
If the date you are weighing leaves less runway than planned, our free QA hours calculator estimates testing hours from your genre, build size and milestone, so you can check what fits before the cutoff.
A sale cutoff is a release date, and a release date is a build date. A Smoke Test fits the week before it: one outside tester spends 8 hours on the candidate you plan to ship by that date, and the bug list comes back while there is still time to fix it or move the date.
Which release dates can still join the Winter, Spring and Summer Sales?
Valve’s rule is short. On the events page, “any game released at least 30 days before the event start date is welcome to participate with a discount.” The discounting rules explain why: a product cannot be discounted for 30 days after release, and seasonal sales are exempt only from the cooldown between two discounts, not from the release cooldown.
Valve’s own worked example uses this exact winter. A fictional game releases into Early Access on 15 November with a 7-day launch discount. Its release cooldown ends on 15 December, so it can join the Winter Sale on 17 December. The launch discount does not block it, because the seasonal sale ignores discount-to-discount cooldowns.
Our cutoffs are on the edge: a release on 17 November ends its cooldown on 17 December, the same day the sale opens at 10am Pacific. A release a day or two earlier removes the doubt.
Valve also describes a late entry. The seasonal sales FAQ says that if your “30-day Price Introduction Cooldown ends during a seasonal sale”, you can join the sale in progress by entering a custom discount once it ends, “30 days or more from your release date or price increase”. Counting back from the last day of each sale, that points to a release by about 4 December for the Winter Sale, 22 February for Spring and 7 June for Summer. This is our arithmetic, not a Valve date, and the later the release, the fewer sale days are left. Valve does not say how a late entry is placed on the sale pages.
Valve itself plays the cutoffs down. The same FAQ says “you shouldn’t feel pressured to change your release date or pricing updates for the sake of a seasonal sale event”, since there are always future discount opportunities.
Why can’t a February Next Fest game discount in the Spring Sale?
This follows from two rules that sit on different Valve pages. The February 2027 Next Fest page requires a participating game to release “any time after the conclusion of the fest on March 1, 2027”. The release cooldown then blocks discounts for 30 days, until at least 31 March. The Spring Sale ends on 25 March.
June repeats the pattern. A June Next Fest game releases after 21 June, its cooldown runs to at least 21 July, and the Summer Sale ends on 8 July. Neither game can join partway, because neither cooldown ends inside the sale.
That is not a reason to skip Next Fest. It means the first seasonal sale a Next Fest game can discount in is a later one: the Summer Sale for a February participant releasing by 25 May, or the Autumn Sale 2027, still undated, for a June participant. Our February 2027 Next Fest QA plan maps the demo deadlines for that edition week by week. A game may appear in only one Next Fest, so the choice between February and June is also a choice of which sale comes first after launch.
Should a new release join a themed fest?
Fests work differently from seasonal sales. Valve’s themed sale events page lists four differences that matter at launch:
- Invitation by tags. Valve selects games whose store tags and store page match the theme, and the game must be primarily about it. A racing mini-game inside an adventure game does not qualify.
- No discount needed. A discount is optional, though “the event page will most prominently feature discounted games.”
- Cooldowns apply in full. Fest discounts follow the 30-day rules, and Valve writes that “no exceptions are possible.” A game inside its release cooldown can take part only at full price.
- Upcoming games have a place. Each fest has sections for upcoming games and free demos, so a Coming Soon game with a fitting theme can collect wishlists there before launch.
Partners “usually have six weeks or more” to register. Where Valve asks for an extra opt-in for the event trailer, the deadline is typically 6 weeks before the start. We could not open the individual fest pages on 4 November 2026, so check each one for its own deadline.
For a release date, the practical reading is this. A fest that matches your tags is useful before launch, as an upcoming game with a demo, or more than 30 days after launch with a discount. In the 30 days after release, it adds a full-price listing below the discounted games.
What changes for a launch that lands inside a seasonal sale?
Three documented effects, none of them a ban on launching. A seasonal sale redesigns the Steam front page around the sale for its whole run, according to Valve’s seasonal sales page. Valve’s wishlist page says notification emails can take longer in high-volume periods, and that the 2-week email cooldown may be extended during seasonal sales. And a game in its release cooldown cannot take a sale discount, so it sits at full price, apart from its own launch discount, while the store is built around discounts.
Our reading is that a launch inside the Winter Sale, the longest of the three and running into the new year, competes with the most discount-focused front page of the year. That is an inference from Valve’s descriptions, not a measured effect. The weekday question is separate, and our release weekday data found no weekday that clearly did better on reviews in September 2026.
Which launch windows does the calendar leave?
The table turns the rules above into release windows. It covers only what Valve documents: discount eligibility and Next Fest timing.
| Release between | First seasonal sale with a discount | Next Fest status |
|---|---|---|
| Now and 17 Nov 2026 | Winter Sale 2026 | Not eligible (released) |
| 18 Nov and about 4 Dec 2026 | Winter Sale, joined partway (our reading of the FAQ) | Not eligible (released) |
| About 5 Dec 2026 and 16 Feb 2027 | Spring Sale 2027 | Not eligible (released) |
| 17 Feb and 1 Mar 2027 | Spring Sale partway for a release up to about 22 Feb; otherwise Summer | A February Next Fest game releases only after the fest ends on 1 Mar |
| 2 Mar and 25 May 2027 | Summer Sale 2027 | February Next Fest games can release here; June needs an unreleased game |
| 26 May and 21 Jun 2027 | Summer Sale partway for a release up to about 7 Jun; otherwise Autumn 2027 (undated) | A June Next Fest game releases only after 21 Jun |
| After 21 Jun 2027 | Autumn Sale 2027 (undated) | June Next Fest games release from here |
