Super Bowl Sunday is the day on which the Super Bowl, the National Football League (NFL)'s annual championship game, is played. It is currently observed on the first Sunday in February, although in 2022 will be moved to the second Sunday, and is sometimes referred to as an unofficial national holiday. The 55th annual event, Super Bowl LV, occurred on February 7, 2021. Festivities for Super Sunday typically involve groups of people gathering to watch the game. Both "Super Sunday" and "Super Bowl Sunday" are registered trademarks of the National Football League.[1] On Guam, it is known as Super Bowl Monday, due to the time zone, the game airs live Monday morning
