Eternal Christmas
Eternal Christmas makes snowfall possible in biomes that normally stay dry or warm, so a winter-themed world can include deserts, jungles and savannas.
What it does
The mod enables snowfall in every biome regardless of its temperature, expanding where snow can generate. Players who want a frosty atmosphere in an otherwise warm world can use it to build winter-themed survival challenges. The natural weather cycle of vanilla Minecraft is kept, because the mod only widens the snow generation rules and does not alter temperature-based weather behavior.
Installation is on NeoForge only. Eternal Christmas is a client and server mod, so server owners and every player need it. It is released under the MIT License and is open source, with its source code and issue tracker publicly available. Files cover 1.21 – 1.21.11, with 1.0.0-1.21.1 for 1.21.11 as the latest NeoForge build, published on 2025-12-23.
