Extended Time

Real-Time Day Cycles

Extended Time gives you total control over the duration of a Minecraft day. Whether you want a realistic 24-hour cycle, a 1-hour "long day," or a custom duration, this mod handles it with precision.

SERVER-SIDE ONLY: This mod does not need to be installed on the client. Players can join your server with a vanilla client.

Features

Smooth Engine

Unlike basic commands that "skip" ticks, Extended Time uses a precise Accumulator Algorithm. It ensures the smoothest possible sun movement achievable server-side by calculating exact tick additions.

Capabilities

• Custom Duration: Set day length to any number of minutes.
• Real-Time Sync: Sync Minecraft sun with your actual server clock.
• Presets: Switch between 24h, 1h, 12h modes instantly.
• No Conflicts: Automatically handles doDaylightCycle.
• Persistent: Settings save automatically.

Mechanics

Vanilla Minecraft runs on a 20-minute cycle. Extended Time decouples game time from tick rate.
