Realtime Day
Syncs Minecraft's day/night cycle to real-world time.
When it's noon where the server is running, the sun is overhead. When it's midnight, it's night in-game. Singleplayer uses your PC's clock; dedicated servers use the host machine's timezone (or one you configure).
Features
- Overworld time follows real local time (dawn ≈ 6:00, noon, dusk, midnight)
- Uses the server/host timezone by default
- Optional IANA timezone override (e.g.
America/Chicago) - Optional on-screen real-time clock in the bottom-right corner
- Sleep still works — after a vanilla night skip, time snaps back to real time
- Reload config in-game with
/realtimeday reload - Server sync works without the mod on clients; install on the client to see the HUD
Config
Created automatically at config/realtimeday.json:
{
"enabled": true,
"showHud": true,
"hudTimeFormat": "24h",
"timezone": "",
"syncIntervalTicks": 20,
"dimensions": ["minecraft:overworld"]
}

Commands
/realtimedayhud— toggle the on-screen clock (any player, saved to your client config)/realtimedayhud on//realtimedayhud off— show or hide the clock/realtimedayhud 12h//realtimedayhud 24h— set 12-hour or 24-hour clock (10:52 PM/22:52)/realtimedayhud format— show your current format/realtimeday reload— reload world time sync config (server / op)
Notes
- Install on the server (or in singleplayer) for day/night sync. Install on the client for the HUD clock.
- HUD visibility and time format are per-player on each client (
config/realtimeday.json). - Requires Fabric API.
