The Steam “Christmas sale” for 2025 is the Steam Winter Sale, which runs from December 18, 2025 to January 5, 2026.

Quick Scoop

  • Start date: December 18, 2025 at around 10 AM PT / 6 PM GMT.
  • End date: January 5, 2026.
  • This Winter Sale is effectively the big Steam Christmas sale for 2025, covering the whole holiday period and into early January.

Why these dates matter

  • Major gaming outlets and sale trackers list the 2025 Steam Winter Sale as running December 18–January 5, aligning with Valve’s usual late‑December schedule.
  • It is the last major Steam sale of 2025 and also overlaps into 2026, so it’s the best time in that window for deep discounts on a wide range of games.

Tips to get ready

  • Build a wishlist: Steam will highlight discounts on your wishlist games during the sale, making it easier to track price drops.
  • Use price trackers: Third‑party sites can show historical lows so you know whether a discount in the Winter Sale is actually good.
