Events concerning the Grand Theft Auto series in 2013.
- Grand Theft Auto V was released for the PlayStation 3 and Xbox 360 on September 17.
- Grand Theft Auto Online was released for the PlayStation 3 and Xbox 360 on October 1.
- The DLCs, the Beach Bum Update, the Deathmatch & Race Creators Update, the Capture Update, and the Holiday Gifts were added to Grand Theft Auto V and Grand Theft Auto Online. All of them were free; however, the Holiday Gifts were only available for a limited time.
- Mock police records on the Grand Theft Auto 2 website are dated between 13/07/13 and 03/11/13. This, along with the game's futuristic setting led some fans to believe that the game takes place in 2013. However, the game's manual uses the phrase "three weeks into the future," and the website's clock is always set three weeks ahead of the current time — this puts forward the idea that the game takes place in an unspecific time and place, fitting with the game's setting of "Anywhere, USA." On top of this, radio host Johnny Riccaro mentions in the game that "the millennium's coming," which would make the possibility that the game is possibly set in 1999.
