DatapacksJava
Slow World
Slows the pace of the world: day–night cycles are 3× longer, item despawn time is extended to 15 minutes, and 3x slower growth and decay.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This datapack slows time progression, item despawn, and natural growth and decay, making the flow of time feel slower and more realistic.
- Day–night cycles are 3x longer (time flows 3x slower)
- Item despawn time is extended to 15 minutes (3x longer than vanilla's 5 minutes)
- Random tick speed is set to 1, making growth and decay 3x slower (slower crop growth, longer leaf decay, etc.)
