Custom Day Cycle

Custom Day Cycle
_Take full control of time in Minecraft._ This datapack allows you to set the duration of Day and Night independently, while maintaining a fully functional multiplayer sleep system and accurate day counting.

Whether you want a 24-hour real-time server, long summer days with short nights, or a hardcore survival experience with endless nights, this datapack handles it all without mods—just vanilla commands.

✨ Features

• _Independent Cycles_: Set Day and Night to different lengths (e.g., a 60-minute Day and a 5-minute Night).
• _Smooth Time Progression_: Time advances smoothly every tick, not in choppy jumps.
• _Smart Multiplayer Sleep_: Set a required percentage of players to skip the night (0% to 100%).
• _Includes a cinematic sleep delay_: The night waits 5 seconds after the percentage is met, allowing players to see the “lying down” animation and screen fade before the sun rises.
• _Accurate Day Counter_: Unlike other time-skipping tools, this pack calculates the exact time for the next morning. Your F3 Day Counter and Local Difficulty will continue to increase correctly.
• _Lag Friendly_: Optimized to run minimal checks when players aren’t sleeping.

🛠️ Commands
_All settings can be changed on the fly using macro commands. You do not need to edit any files._
