It's been 36 years since the Celtics have lost on Leap Day. Their 102-98 loss to the New York Knicks on Feb. 29, 1984, snapped a five-game Leap Day win streak for Boston that dated back to the start of the NBA.
After not playing on Feb. 29 for two decades, Boston started a new streak in 2004 and has won four Feb. 29 games in a row.
