The National Football League occasionally schedules matchups on Christmas, December 25 or Christmas Eve, December 24. Unlike their November holiday counterparts, the Thanksgiving Classic games, Christmas Day and Christmas Eve games in the National Football League are not a regular annual part of the NFL''s schedule; rather, the NFL only schedules a Christmas game on a night when football would be played anyway, and has only scheduled regular season games on Christmas Day since 1989. In recent years, the NFL has generally scheduled games on Christmas only if it falls on a day normally used for games (Saturday, Sunday, and Monday); as of yet, it has never scheduled a Christmas or Christmas Eve game on a Thursday, though it has scheduled Christmas games on Friday, which is one of the only times the league ever plays regular-season games on that day of the week. If Christmas falls on a Sunday, as it did in 2005, most of the games will be played on the preceding day (with no games that night or the following afternoon in deference to the holiday), and then one or two games are scheduled for Christmas Night to be broadcast nationally.
