The NBA Playoffs always begin in late April, with eight teams in each conference qualifying for the playoffs. The top three seeds for each conference are determined by taking the winners of the conference's three divisions and ranking them by regular season record. The remaining five seeds are determined by taking the five teams with the next-best records from among the non-division winning teams in the conference. However, the seeding system has one feature that is unusual in North American sports; division champions do not necessarily have home-court advantage in the playoffs. Although the playoff brackets are not reseeded, home-court advantage is based strictly on regular-season record, without regard to whether a team won its division.
