Extra Long Days
by smami
Extra Long Days lengthens the Minecraft day and night cycle, so each part of the day lasts longer than in vanilla play.
What it does
The mod is a datapack that stretches the day and night timers. Players can set day and night to run between 20 minutes and 2 hours, and the daylight cycle slows to a sixth of its normal speed when the longest settings are chosen. Versions for Fabric, Forge, NeoForge and Quilt are published, and the datapack is also available for servers, covering 1.20 – 1.21.11.
Only the server needs the mod for the timers to change, while players may add it to their own game. It works alongside other mods for the same world, though the author notes major compatibility issues with some of them. The mod is released under the GNU Lesser General Public License v3.0 or later and is not open source.
Key features
Adjustable day and night length
Day and night phases can be extended from 10 minutes up to 60 minutes each, with presets for 20 minutes and 2 hours.
Slowed daylight cycle
The daylight cycle can be slowed to one sixth of its normal speed, so dawn and dusk arrive far less often.
Datapack removal steps
Before removing the pack from a world, two commands should be run on the server so the timers return to normal.

How it compares
Longer Days is also a server-side option, released under the MIT License and open source, for 1.20.3 – 1.21.8. Day Length takes a different route, running on both client and server with files for 1.14.4 – 1.21.6 under the GNU General Public License v3.0 only.

What the author says
Extends the length of a Minecraft day, from 20 Minutes to 2 Hours, by very simply slowing down the daylight cycle to 1/6th speed. This is a datapack, and thus entirely server-side and not needed on the client unless you are playing singleplayer
