48 minutes of play, about 2 h 15 min overall
NBA quarters last 12 minutes, so a game has 8 minutes more playing time than under FIBA rules. Breaks between quarters are short and half-time is 15 minutes; with timeouts and TV breaks the tool estimates 2 h 5 min to 2 h 24 min. A 7:30 pm tip-off usually ends between 9:35 and 9:54 pm. Ties are settled by 5-minute overtimes, each adding roughly 10–15 minutes.

- 3Enter the start time and tick “Include overtime” for knockout games.
- 4Read the playing time, scheduled breaks, estimated real time, finish-time range and the period-by-period timeline.
Why the clock and the real time differ
Soccer runs a continuous clock: 90 minutes plus stoppage time and a 15-minute half-time make about 1 h 50 min. Basketball, ice hockey and the NFL stop the clock whenever the ball or puck is dead, so 48 NBA minutes become roughly 2 h 15 min and 60 NFL minutes more than three hours. Tennis and volleyball have no clock at all, so the calculator uses typical minutes per set. That is why the result is a range, not one number.
Planning examples
A 7:30 pm NBA tip-off usually ends between about 9:35 and 9:55 pm. A Premier League 3 pm kick-off finishes around 4:51–4:57 pm. An NFL 1 pm game runs to roughly 4:02–4:17 pm, and a best-of-three tennis match that goes the distance takes about 1 h 50 min to 2 h 35 min. Cup ties with extra time and penalties add 40–60 minutes; TV timeouts and long video reviews stretch every estimate.
