NotifReminder

A reminder can start at a clock time such as 15h15, 15h or 15:15, or at an offset from now such as +10min. Once it has fired, the reminder can be set to recur at a fixed gap, written as a whole number followed by one unit letter such as s, m, min, h or d, so 5s or 365d both work. Each reminder is delivered through chat, title, toast or a mix of them, and the sound played can be picked by a short name such as bell, chime, xp, ding, pling or levelup, or by a full game sound id such as block.anvil.fall, music disc or lava chicken.

Reminders are stored on the client, so nothing is sent to the server and the mod works with any server. Disconnecting, changing worlds or restarting the game entirely leaves every reminder in place. A reminder that has fired stays in the list marked as done, and it can be started again. On the next login the mod lists the ones that triggered, so a reminder is never lost before it is seen. Message text can use Minecraft's formatting codes, while ampersand codes are left alone. The HUD can pin a live countdown for the next reminder.

The build targets Minecraft 26.1.2 only, with Fabric Loader 0.19.3 or newer and Fabric API required. It runs on the client alone, so only the client needs it and servers do not. Files are released under the MIT License, which is not open source.
