WWE SummerSlam 2025 is a historic two-night event held at MetLife Stadium in East Rutherford, New Jersey. Each night starts at 6 p.m. ET, with the preshow beginning at 3 p.m. ET. The event spans two days, August 2 and August 3, featuring a total of 12 matches. Given the length of similar WWE events, each night's main card likely runs approximately 3 to 4 hours, with the preshow adding an additional 3 hours collectively over both nights. Therefore, the entire SummerSlam weekend, including the preshows, could extend beyond 8 to 10 hours in total. This format marks the first time SummerSlam has been held over two nights, similar to WrestleMania's recent format expansion. The extended duration reflects the event's growth and the increased number of matches, making it one of WWE's biggest shows of the year.
