A standard ice hockey game has three periods in regulation time, each lasting 20 minutes of stop-time play.

In most common formats (like the NHL and international play), that means:

  • 3 periods × 20 minutes = 60 minutes of regulation play.
  • 2 intermissions of about 15–18 minutes each between the periods.

If the game is tied after those three periods, different leagues may add overtime and possibly a shootout, but those are extra beyond the basic three- period structure.
