2 Day was a channel event celebrating the number 2 on February 2, 2018, or 2/2.
SiIvaGunner contributor Twonko often used the number two, more specifically the number rendered as "2", as an in-joke on their channel. The contributor made several YouTube videos of songs that cut off after the word (or syllable) "two". This in-joke appeared on SiIvaGunner as an Easter egg in the CCC episode "An Acrimonious Assault", and in the rips "Rick the Hamster - Kirby's Dream Land 2", "Two - Yoda Stories", "Dimension Heist - UFO Special Stage - Sonic Mania and "SONG 6 (PART 2) - EXTREME PAINTBRAWL". It eventually culminated in this event.
Every rip uploaded during this event had the number "2" in its title.
