Dynamic Daytime

by imalittlhigh · on Modrinth

Changes length of day and night depending on the number of days you played. Free Minecraft Java datapack for 1.21, 1.21.1, 1.21.2.

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.

Mod loader

Minecraft version

⬇ Download for 1.21–1.21.5 · Data pack⬇ Download for 1.21–1.21.5 · Fabric⬇ Download for 1.21–1.21.5 · Forge⬇ Download for 1.21–1.21.5 · NeoForge⬇ Download for 1.21–1.21.5 · Quilt
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.

Want your World to feel more dynamic?

This Datapack adjusts the length of the Day/Night cycle depending on the number of days the world is played.

I have implemented a yearly cycle. One year is 100 Days to not make it to long. After 100 Days have passed the cycle starts anew.

Day and Night change length from 0.5x to 2x normal speed. If the Day is 0.5x speed, the Night will be 2x speed.

You start in the middle of "summer" so your Days will be twice as long as normal Days and your Nights twice as fast.

These come from our own check of the pack file, not from the source page.
