average spent at nba game
Â· just now. Report Abuse. The average time period for an NBA game is 2 hrs. and 30 minutes. If the game goes on OT, especially on a double OT, then it may extend up to 3 hours. So to answer your question, if the game starts at 7:30 PM, then it will be finished at around 10 PM if it is a regular game. But it it goes on OT, or a double OT, then it would be complete at around 10:30 PM. Good luck to you and God Bless you.
