Steam Halloween, Autumn, and Winter sale data has been leaked. Whoops. We now have the exact start and end times of the three major upcoming Steam sales, so it's time to start planning around them!
These dates have been revealed in a developer-specific Steam forum, only to get leaked practically immediately. This time around, it's due to a supposed loophole saying that developers aren't allowed to post about the sales on their own websites and Steam Community, but mentions nothing about Twitter.
Whether this is true or not - we cannot say, but we can tell you all about the dates! The first up-and-coming sale will, obviously, be the Halloween sale, which also makes for the shortest of the three.
Steam Halloween Sale Start and End Times
-Monday, October 29th at 10 AM PT/1 PM ET/5 PM GMT
-Thursday, November 1st at 10 AM PT/1 PM ET/5 PM GMT
Steam Autumn Sale Start and End Times

Steam Winter Sale Start and End Times

Now, of course, not only can these dates change post-leak, but they should also be taken with a pinch of salt, as Valve aren't usually keen on widely announcing sale dates. All the same, this primer might come in handy in case the dates do not change!
