When does the 2009-2010 NHL regular hockey season end?

In the NHL, the regular season ends in early April (this season all 30 teams play their final game on April 7th). The playoffs begin shortly after and 4 rounds of best of 7 play usually ends early to mid-June. (playoff schedule doesn't come out until later, but last season game 7 of the finals was June 15th, and regular season ended on April 10th).
