Date Time Display
by okdashi
Date Time Display puts the in-game date, time and weekday on a top-of-screen overlay, with its calendar tracked to match the real world.
What it does
The overlay shows the current in-game time, weekday and date. The day tracker mirrors the real calendar: an in-game April 6 2025 lands on the weekday April 6 2025 has on Earth, and leap years follow the standard 4-100-400 rule. Day-of-year is worked out with modulo and floor division on the game ticks, and the weekday uses Zeller's Congruence. Recalculation happens from the tick time, so setting the time with a command does not throw the date off.
Movable holidays, including Easter, Lunar New Year and Thanksgiving, are worked out with the same formulas that astronomy software relies on. Special events fire at set moments: a firework show in chat at midnight on New Year's Eve outdoors, fireflies appearing on Lunar New Year, hearts on Valentine's Day and green particles on St Patrick's Day. Addon packs can attach their own actions to holidays through ready-made hooks. Installation needs Fabric API on Fabric. The mod is published for Fabric, Forge, NeoForge and Quilt for 26.1 and earlier builds, and a data pack version exists for servers that want the same calendar.

How it compares
Clock Mod is a Fabric-only, client-side mod for 26.1.2 under the CC0 1.0 Universal license and is open source, so only the client needs it. Real Events runs on Fabric, NeoForge and Quilt for 1.21 – 1.21.11, needs both sides, and uses a custom license that is not open source. Timekeeper (Calendar) covers Forge and NeoForge for 1.20.1 – 1.21.8 with both sides required under a Creative Commons Attribution Share Alike 4.0 license, not open source.
