Valve has launched a separate page called “Steam Results” where each player can view their personal stats for the past 12 months. The statistics collected take into account the playing time from the first second of January 1 to the last second of December 14 (according to Greenwich).
So there was no offline or offline game time. Also excluded are tools, third-party software, and unreleased or deleted Steam games.
On their profile, players can see the time spent in games, the number of achievements, preferred genres, community activity, and so on.
You can check out your Steam results for 2022 at this link.
