Weather Watch
by Consular
Weather Watch syncs the world's day and night and weather to the real-world season, hemisphere and clock of the server.
What it does
The mod ties in-game time and weather to the real calendar. Months map to the season, and the season depends on the hemisphere where the server is located. In multiplayer the mod reads the server clock, so every player sees the same conditions. Time Sync is off by default, and it can optionally follow the system clock for the day and night cycle.
Weather Watch is a server-side mod: only the server needs it, and players join without installing anything. Survival worlds are not the intended target, since the mod removes the ability to skip the night with a bed. Peaceful worlds and roleplay servers are the better fit. The author notes that the mod literally fast forwards or rewinds with the American Daylight Saving Time change, which is a deliberate side effect.
The mod is released under the Creative Commons Attribution No Derivatives 4.0 license and is not open source, though its source code is public.

Key features
Real-world seasons
In-game months follow the calendar, so the season changes with the actual month of the server.
Hemisphere-aware seasons
The season depends on the hemisphere where the server is located, so northern and southern servers differ.
Server clock sync
Conditions are read from the server clock, so every player in a multiplayer world shares the same time and weather.
Optional system clock time
Time Sync can follow the system clock for the day and night cycle; it is off by default.

Who it’s for: Server owners running peaceful or roleplay worlds, and players who want in-game weather to follow the calendar. Traditional survival is not the intended audience, since bed skipping is removed.
How it compares
Client Time is client-side only and open source under the GNU General Public License v3.0 only, for Fabric and Quilt on 1.20.2 – 1.21.11, so it changes only the local view. Server Chat Sync is server-side only under All rights reserved, for Fabric and NeoForge on 1.20.5 – 1.21.10, and handles chat rather than time. Weather_block runs as client and server under All rights reserved on Fabric and NeoForge, 1.20.4 – 1.21.8.

The months corresponding to each season depends on the hemisphere you're located in* In multiplayer, it'll simply refer to the server clock ## Time Sync (off by default) Optionally, Weather Watch can also sync the day time to your system clock as well! This isn't recommended for traditional survival, as it does…
