OnTemp

by Jgers1

OnTemp puts world time, weather and moon phase information on a client-side screen and in hints, for players who want those readings without leaving the game.

FabricClient-side onlyMIT LicenseOpen source1.21.1

What it does

Installed on the client, OnTemp shows the world time along with other details about the current world, such as weather and the phase of the moon. A time bar screen gathers these readings in one place, and hints add extra information where it is useful. Only the player's own installation needs the mod, so a server does not have to run it for it to work.

The mod is configurable through YetAnotherConfigLib, which it uses for its settings screen, and it can be reached from the Mod Menu list. Fabric API, Mod Menu and YetAnotherConfigLib (YACL) are all required. Files exist for Fabric only and cover 1.21.1, with 1.0.0 as the latest file, published on 2026-07-03 under the MIT License. The source code is public, and the project is open source.

Key features

  1. Time bar screen

    A screen that shows the world time as a bar, so the current hour can be read at a glance.

  2. Weather and moon phase

    Weather and moon phase readings are shown alongside the time, so the current conditions are simple to check.

  3. Hints with extra information

    Short hints supply additional details about the world while playing, without a separate menu to open.

  4. Detailed configuration

    The options screen lets the player adjust which readings appear and how they are displayed.

How it compares

Full comparison

Moon Info Updated is also a client-side Fabric mod under the MIT License, built for 1.21.1, and it focuses on the moon phase rather than the whole set of world readings. BetterTotemHighlight is open source under the MIT License as well, but it is client-side only for 1.21.4 – 1.21.8 and does not show time or weather, so it covers a different job.
