The National Hockey League's trade deadline is calculated as the 40th day before the final day of the regular season, ensuring that it typically falls during the last week of February or the first week of March. Much like Major League Baseball and the National Basketball Association, the NHL's trade deadline is often a period of increased player movement; teams that are either making a final push to secure a playoff spot or hoping to go deep into the playoffs attempt to trade to acquire key veterans or proven scorers in order to solidify their rosters. Conversely, teams that are rebuilding with younger players may be willing to trade away their more expensive players in order to "dump" (reduce) salary and get draft picks/prospects in return.
