Timekeeper (Calendar)
by Lunakibby
Timekeeper adds a craftable calendar to Minecraft, so a world can show the current day and year at any time.
What it does
A calendar item is crafted and used in the world to read out the date. Players can find out which day and year the world is on without leaving the game or checking outside tools, which makes it easier to record a world's history by exact day. The mod is meant for players who keep a timeline of events in a world.
Timekeeper runs on both client and server, so the server and every player need it. Files exist for Forge and NeoForge across four game versions, 1.20.1 – 1.21.8, with the latest release on both loaders dated 2025-12-01. It is released under the Creative Commons Attribution Share Alike 4.0 license and is not open source. Timekeeper pairs with the Real-Time calendar convenience version, and it is compatible with the 96 day year cycle of Serene Seasons.
