ShutdownTimer
by qw1zzr
ShutdownTimer lets server owners schedule automatic shutdowns and restarts, with countdowns announced to players in chat before the server stops.
What it does
A server owner sets a shutdown or restart time and the mod announces it in global chat. Warnings go out at 10 minutes, 5 minutes, 1 minute, and as a five-second countdown before the server stops. Before shutdown, connected players are disconnected gracefully rather than cut off mid-action.
The timer accepts durations in seconds, minutes, hours and days. Command syntax auto-completes in the chat, which helps when entering longer schedules. The mod is a Fabric and Quilt project that runs only on the server, so players join without installing anything, and a lightweight design keeps its footprint small on a busy host.
Installation covers Fabric and Quilt only, for game versions 1.21 – 1.21.11 across 12 release versions. It is released under the MIT License and is not open source. The author plans to update more Minecraft versions and add features if the mod gains interest.
Key features
Scheduled shutdowns
Automatic shutdowns and restarts run at a set time, so the server stops without manual intervention.
Chat countdown warnings
Global chat messages warn players at 10 minutes, 5 minutes, 1 minute and in a final five-second countdown.
Graceful disconnects
Players are removed from the server cleanly before shutdown, rather than being dropped mid-session.
Duration units
Timers accept seconds, minutes, hours and days, so both short restarts and long maintenance windows can be set.
Command auto-completion
Command syntax completes automatically while typing, which reduces mistakes when entering schedules.
