Splatfest will begin on August 28th, at 9PM PT. Once the event begins, players will have a full 24 hours to rack up wins for their side. In other words, you have until August 29th at 9PM PT to get those wins in.
For those in EST, Splatfest begins at midnight. Those in BST, Splatfest begins at 5AM. However, before you start thinking about completely wrecking the other team though, don’t forget to choose which side you’re on in Splatoon and get your free t-shirt (which will unfortunately disappear once Splatfest is over) to represent your team.
