What day should you release your game on Steam?

Most of a launch takes months: the page, the trailer, the demo, the wishlists. The date takes a calendar and an hour. It will not save a weak game, but a bad one can bury a good game under a sale, a blockbuster or a weekend with nobody at Valve to help, so it is worth the hour.

The obvious question is which weekday sells best, and the internet is full of confident answers: Tuesday, Thursday, never Tuesday, always Monday. None of them comes with data Valve has published, and How To Market A Game's 2023 look at the question ended with a preference, not a measurement. What does exist is a set of Valve rules, a few hard numbers about Steam's launch lists, and practical reasons. Those are enough to pick well.

Valve's Release Dates documentation sets the rules that matter:

• Weekends are allowed but not recommended. The release-date picker hides Saturdays and Sundays, and Valve notes the Steam team may not be available to help with release problems on a weekend. The Release button still works if you press it.
• The date locks two weeks out. You can change the release date until two weeks before it. Inside that window the game shows more in upcoming lists and the date can no longer move.
• Show a vague date, keep an exact one. Players can see an exact date, a month, a quarter, a year or Coming Soon, but Valve asks for a specific intended date behind it, because it uses that date for reminders and event invitations.
• Vague dates sort last. A month-and-year date is listed as the month's last day, and a game with no date appears behind games with specific ones.

With no published data, the reasons developers give for Monday to Thursday are practical:

• Press and creators work weekdays. Launch-day coverage needs someone to publish it, and a review embargo that lifts on a Saturday lifts to an empty room.
• You need working days to fix things. A launch-day crash on a Friday night is a weekend without Valve's help and, for a solo developer, without sleep.
• The first days count. A midweek launch gives the game several days of sales, reviews and word of mouth before the weekend, when more players are online.
• Steam's weekly maintenance usually falls on Tuesday afternoon Pacific time, which is why some developers avoid launching late on a Tuesday.

Release in the morning US Pacific time, around 10 a.m. when Steam's own events start, so Europe is still awake and the Americas have the whole day.

• Mind the 30-day rule. A game must have released at least 30 days before a seasonal sale starts to join it, and cannot be discounted for 30 days after release. The last days to launch and still make the next sales are 17 November 2026 for the Winter Sale, 16 February 2027 for the Spring Sale and 25 May 2027 for the Summer Sale.
• Avoid Next Fest weeks, when the front page is given to thousands of demos: 22 February to 1 March and 14 to 21 June 2027.
• Check your genre's calendar. A big release in your genre pulls the same players, the same press and the same tags. SteamDB's upcoming lists show what is coming.
• Look at the themed fests. A fest for your genre a few weeks after launch is a second showing; one in the launch week puts you among every discounted game in your genre.

Our Steam sale calendar has every published event through June 2027.

Conventional advice says never launch during a seasonal sale. Chris Zukowski's daily scrape of Steam's launch lists in January 2026 complicates that. Popular Upcoming, the list of unreleased games about to launch, took about 5,000 to 7,000 wishlists to enter; the median game stayed on it for one day, and outside the Winter Sale about four days was the realistic best. Inside the sale, when few developers launch, a game held its place for a full week.

Where it breaks: a game launching during a sale cannot join that sale (it is in its 30-day cooldown) and competes on price with thousands of discounted games. Zukowski's own conclusion is that front-page placement amplifies a game players already like rather than creating demand. So a sale-week launch suits a game with enough wishlists to reach the launch lists and a page that converts at full price; it does not suit a game that needs a discount to be noticed.

1. Count back the hard minimums. For a first title, 30 days after paying the Steam Direct fee; the store page Coming Soon for at least two weeks; store page and build reviews of about 3 to 5 business days each.
2. Mark the calendar six months ahead: seasonal sales and their 30-day cut-offs, Next Fest, themed fests in your genre, and big releases in your genre.
3. Choose the week that clears all of them and, if you want a sale as your second wave, falls more than 30 days before it.
4. Choose Monday to Thursday in that week, a day you, your press contacts and your creators can all work.
5. Show a month or quarter publicly until you are sure, with the exact date set behind it in Steamworks.
6. Commit before the two-week lock. Once inside two weeks, the date cannot move; set the launch discount before release, too.

Pick a date you can staff. Launch week is support, patches, review replies, streams and press, all at once, and there is only one of you. Clear the week before and after of everything else, prepare the posts, emails and store-page event in advance, and choose a weekday so the people you rely on are working too. A date that suits the algorithm and not you is the wrong date.

Flockbay is a free AI game builder on the official Godot engine. It prepares the Steam page as a .zip you upload yourself, cuts launch trailers from your real gameplay, drafts the launch posts and posts to TikTok, and reads your followers and wishlists so you can see whether the game is near the Popular Upcoming threshold before you commit to a date. Its Steam numbers are free; the other publishing tools are free in beta until 1 December 2026. The date and the Release button are yours in Steamworks.
