How do I install ActiveTime?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does ActiveTime work with?

The listing gives Minecraft 1.20.3, 1.20.4, 1.20.5, among others. This is the version stated by the author or source site, not something we verified ourselves.

ActiveTime

Your world only progresses while you play. Automatically freezes the Minecraft simulation when no players are online.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

ActiveTime

Your world only progresses while you play.

ActiveTime is a lightweight server-side mod/plugin built for private SMPs, co-op groups, and modded survival playthroughs.

Leaving a 24/7 server running shouldn't punish you. When nobody is online, world progression shouldn't advance needlessly—seasons shouldn't rotate, days shouldn't tick away, and time-based difficulty shouldn't scale up while everyone is asleep.

Using Minecraft's native tick simulation freeze (1.20.3+), ActiveTime automatically pauses the world the moment the server is empty, and resumes instantly before the next player loads in.

Available for: Paper / Purpur, Fabric, and Forge (1.20.3+)

Why use this?

Scenario	Vanilla / Default Server	With ActiveTime
Everyone is offline	Days cycle needlessly, seasons pass, crop timers run out	World simulation freezes completely in place
Modded progression	Difficulty scales up, food spoils while you sleep	All mod timers (seasons, day counters) pause safely
A friend joins at 3 AM	They wake up to a different in-game week	Resumes instantly right where the group left off
