CReminder

A reminder is created with the creminder command, and the time can be given in seconds, minutes, hours, days or weeks, combined in one value like 2d or 1w2d6h. When the time runs out, the reminder appears in chat with colored formatting that stands out from ordinary messages, along with a note of what to do next. The reminders are saved locally in the Fabric config folder, so they survive restarts of the game.

The mod is built for recurring tasks such as voting, claiming kits, checking farms or collecting rewards, and for keeping track of a timed activity like playing a game. Reminders can be tied to a command that has already run, such as a vote or kit command, and the mod watches commands sent from the client. Commands with arguments, such as kit hourly10, can be wrapped in quotes when the reminder is created. After the tracked command runs, the timer restarts on its own, and a recurring reminder rolls forward after it triggers.

The mod runs on the client alone and works in single-player as well as on multiplayer servers, so a player can install it locally without asking a server owner to add anything. Files are published for Fabric only, for Minecraft 1.21.10, and the mod needs Fabric API and Java 21 or newer.
