-The period ends when the last jam ends, NOT when the clock runs down. The jam ends when the referees blow the fourth whistle, either because the lead jammer called it off (hitting her hands on her hips), because the full two minutes of the jam elapsed, or because of injury/interference.
-If there is more than thirty seconds left on the clock, a new jam will begin. If there are less than thirty seconds left, there will ONLY be another jam if either one of the teams calls a time out. If neither team calls a time out, the clock will run down and the period will end.
So the next time you're sitting in Kicks waiting for the last jam of the game to end, don't just watch the clock. Watch the jam--it may change the outcome of the game!
