The 2021 NFL season features a rarity as the league puts on multiple Christmas Day games for only the sixth time in history.
In fact, Christmas Day has included a grand total of 20 regular-season games and two postseason contests. However, as you can probably imagine, the NFL has capitalized on its ever-growing popularity and increased its volume since 2000. Fifteen of those regular-season matchups have happened during this millennium.
And these are truly special games, too. Although the holiday fell on a Sunday in 2005, 2011 and 2016, the NFL played a heavy majority of its schedule on Saturday each of those years.
