Roblox's Halloween happens game by game: each game runs its own event and dates it on its event page on Roblox. On October 8, five of the most played games already have one live, and October 17 is the big day, when Evade, RIVALS, Dress To Impress, Fisch, 99 Nights in the Forest and Jujutsu Shenanigans start theirs.
Below is every Halloween event that the games of our most played Roblox games have published, with its dates and what its developer announces. Times are in UTC, and each event name opens its page on Roblox, where you can ask to be notified.
