DayTimeControl

Vanilla Minecraft uses one fixed cycle for day and night. DayTimeControl replaces it with two independent settings: the number of ticks for daytime and the number for nighttime, with a standard value of 12,000 each. Raising the daytime value makes days longer, and raising the nighttime value makes nights longer. Whether a server wants a long summer with extended days or a harder survival experience with lengthened nights, both can be set with a few configuration changes.

The mod scales the game clock toward the desired tick counts rather than jumping to them, so the transition stays smooth. An admin command freezes the sun and moon at once and a second call resumes the cycle under the custom configuration, which suits map makers waiting for players to finish setting up an event. DayTimeControl also manages the doDaylightCycle gamerule automatically so its own timing logic takes priority over it.

DayTimeControl is server-side only, so players join without installing it. It is published for Forge only, across six release versions 1.20.1 – 1.20.6, and the latest file is 1.0.0 for 1.20.6. The mod is not open source and is licensed as All rights reserved.
