The NBA trade deadline is one of the key calendar dates of the season. After the deadline, no trades can be made until the end of the season. Each year the NBA trade deadline is towards the latter part of February, usually around February 21 (Feb. 21 in 2008, Feb. 22 in 2007, Feb. 23 in 2006, Feb. 24 in 2005, Feb. 19 in 2004, Feb. 20 in 2003) give or take a few days. Looking at NBA trade deadline history is always interesting. There are usually a bunch of deals, but they're often smaller in importance than expected.
