Troubleshooting a Calendar Slot That Still Appears in Your Inventory

Check That the Pack Is in the World Folder

A common mistake is placing a data pack into the main mods or resourcepacks directory instead of the save-specific datapacks folder. Unlike the main SeasonHUD mod—whether you use the standard version or the Fabric version—a data pack only affects individual saves that contain it. Open your singleplayer menu, select your world, click Edit, and click Open World Folder to verify the pack is inside that save's datapacks folder. On a multiplayer server, the pack must be placed inside the server world's datapacks folder rather than on your client alone.

Verify Pack Status and Refresh Your Session

Even when placed in the right directory, a data pack can remain in the available queue without running. Open your chat window while playing in your world, type /datapack list, and press Enter to read the chat output. Confirm the pack is listed as active; if it appears as available instead, turn it on using /datapack enable. If the calendar slot still lingers on your Curios, Trinkets, or Accessories screen after confirming the pack is active, exit to the main menu and reload the world so your accessory slots refresh.
