Day Length

Day Length gives you absolute control over Minecraft's time progression. Whether you want a strictly realistic 24-hour cycle or custom-speed days for your unique playstyle, this mod handles it with precision and smoothness.


🚀 Features

  • Custom Day Duration: Set the day-night cycle to any length you want (e.g., 40 minutes for double length, or 48 hours for extreme realism).
  • Real-Time Synchronization: Sync Minecraft time with your system clock or a specific UTC offset.
  • Smooth Transitions: No more sun/moon jitter. Time progresses smoothly tick by tick.
  • Vanilla Sleep Support: Players can still sleep to skip the night normally (available when not synced with real-time).
  • Easy Configuration: Direct access to configuration from the in-game mod list.

🛠️ Configuration

Day Length uses a standard configuration system. You can find the config file at: .minecraft/config/daylength-common.toml (or similar depending on your loader/version).

In-Game Access

  1. Go to the Mods menu in Minecraft.
  2. Select Day Length.
  3. Click the Config button.
  4. The configuration file will open directly in your system's default text editor.

Settings

  • customDayLength: Set the length of the day in minutes (Vanilla is 20).
  • realTimeSync: Toggle synchronization with real-world time.
  • manualUtcOffset: Adjust time if using real-time sync with a specific timezone.
  • smoothTimeTransition: Enables gradual adjustments when syncing time.

💾 Installation

  1. Download: Get the correct JAR for your version and loader from GitHub, CurseForge, or Modrinth.
  2. Mod Loader: Ensure you have a compatible mod loader installed.
  3. Deploy: Place the file into your .minecraft/mods folder.
  4. Launch: Start the game and enjoy your custom time!
