realday
by Lumix12
RealDay replaces the default 20-minute Minecraft day with a real-time cycle in which one full in-game day lasts 24 real-world hours.
What it does
Roleplay servers and long-term survival worlds can use RealDay to tie the passage of in-game time to the clock. The day length is configurable, so a server owner can keep the 24-hour default or set shorter days. Only the server needs the mod, since clients join without installing anything and the changes happen on the server side.
RealDay is built for Fabric and is published for 26.2 only, with version 1.0.0 as the latest file, dated 2026-06-26. It is lightweight and optimized to stay server-friendly, and its author says it is compatible with other Fabric mods. The mod is released under the MIT License and is not open source.
