25 Days of Nickmas

25 Days of Christmas was a programming event that aired on the NickToons network in December 2020. Each night, the network aired at least an hour of Nickelodeon Christmas specials at 9:00 PM EST, notably including Christmas episodes of Nicktoons that are no longer on the channel's regular schedule. The event culminated in a 24-hour marathon of the Christmas-themed episodes of The Loud House and The Casagrandes, beginning at 5 PM on Christmas Eve and ending at 5 PM on Christmas Day.
Despite the channel's name, several of the programs that aired in this block are live-action.

Oddly, NickToons aired more Christmas specials on certain days than just the ones that were designated with the "25 Days of Nickmas" banner. The specials that aired outside of the "25 Days of Nickmas" time slot are highlighted with a grey background.
