How to Change Day and Night Durations

By default, a full Minecraft cycle of one day and one night lasts 20 real-life minutes. With the Custom Time Cycle Mod installed, you can lengthen or shorten both daytime and nighttime directly through in-game commands.

Enabling Command Access

Because modifying the time cycle requires running a command, make sure you have permission to use cheats:

1. In a singleplayer world where cheats were disabled at creation, press Esc, click Open to LAN, toggle Allow Cheats: ON, and start the LAN world.

2. On a multiplayer server, ensure your account has operator permissions.

Modifying the Time Cycle

Time adjustments only apply to the dimension your character is currently standing in, so make sure you are in the Overworld—or whichever dimension you want to edit—before starting.

1. Open the chat window by pressing T or /.

2. Type /timecycle set followed by a space.

3. Follow Minecraft's built-in command prompt suggestions above the chat bar to enter your desired durations for both the day and the night, then press Enter.

4. Open chat again and run /timecycle status to confirm your new day and night durations are active in the current dimension.

Once applied, the sun and moon will immediately adjust to moving at your newly configured pace while keeping the rest of the world running at normal speed.
