Real Serene Seasons
by cintreck
Real Serene Seasons makes the seasons of Serene Seasons follow the date on the clock, so the season a world shows matches the time of year outside.
What it does
The mod syncs the real-world calendar into Serene Seasons. The cycle can be set to a year-long run of months, weeks or days, with optional smooth time-of-day interpolation, and a timezone setting decides which calendar date counts as current.
Installation needs Fabric API and Serene Seasons, both required. Cloth Config API and Mod Menu are optional: with them, a hemisphere toggle and other tweaks can be changed in-game. The mod runs on client and server, so the jar goes on the server and every client. Players who join always see the season state tied to the calendar, and it works with the Serene Seasons dimension whitelist. Files are published for Fabric for game versions 1.21.3 – 1.21.10, and the code is open source under the CC0 1.0 Universal license. The latest Fabric file is 1.0.4 for 1.21.10, updated 2025-10-07.

How it compares
Seasonal Let's Do is server-side only and open source under the Apache License 2.0, with files for Fabric, Forge, NeoForge and Quilt across 1.20 – 1.21.11, so clients need nothing installed. Stardom's Sync is also client and server, but it is published for Fabric alone across 1.21 – 1.21.11 and is not open source, and Seasons&Scarcity:Core is client and server with a single 1.21.11 build and no open source.
