RealWorld Sync
by StutelYT
RealWorld Sync ties the Minecraft day and night cycle and weather to the real clock and the real sky, so the in-game world follows the outside world.
What it does
Each in-game day runs on a real 24-hour cycle at one minute of real time per minute in the game, and daylight and nighttime follow the system clock. Weather is taken from live real-world data through the Open-Meteo API, so rain outside brings rain into the world. Time and weather commands are disabled to keep the experience intact, and a small overlay in the top-left corner shows the current real-time weather status, which can be toggled with H. The mod is published for Forge only, for 1.20.1, and it needs to run on both the client and the server.
Key features

Live weather sync
In-game weather is matched to real-world conditions fetched from Open-Meteo.
Command override
Time and weather commands are disabled so the world cannot be changed against the real clock.
