So, I know in my solo play game at 50% my day takes about half an hour, but when playing multiplayer with my husband it takes considerably less time and we can't get much done in a day? Are we the only ones with this issue? Or is this deliberate? We are on Xbox S'.

My previous experience with Stardew Valley when that game released multiplayer seems to match what I saw with Coral Island comparing multiplayer to solo, which is that the in-game time itself isn't faster. However, it also doesn't automatically pause when opening menus or interacting with dialogue like it does in single player. (Since it would be really annoying for the other players to have their games autopause when one person opens a chest, for example.) This makes the irl time per day much shorter without all those short pauses. Could this be what you are experiencing?
