🍂 Ecliptic Seasons

A seasonal environment mod inspired by the 24 Solar Terms.

Spring rain drifting across distant fields.

Long summer days filled with the sound of insects.

Autumn forests slowly turning gold and red.

Snow quietly gathering during the longest nights of winter.

Ecliptic Seasons is a standalone seasonal environment mod inspired by the traditional Chinese 24 Solar Terms.

Rather than treating seasons as a simple switch between spring, summer, autumn, and winter, the year is divided into twenty-four distinct periods. Weather, temperature, daylight length, vegetation, agriculture, wildlife, sounds, particles, and environmental atmosphere all evolve alongside the passing seasons.

Our goal is simple:

Make Minecraft feel like a world where time truly passes.

🌱 Feel the Seasons

The world follows a complete cycle of four seasons and twenty-four solar terms.

Instead of abrupt transitions, the environment changes gradually throughout the year.

• Dynamic seasonal progression
• Twenty-four solar terms
• Seasonal daylight length
• Long summer days and long winter nights
• Smooth seasonal transitions

As the year progresses, the world naturally transforms around you.

🌦 Dynamic Weather & Snow

Weather is no longer limited to vanilla Minecraft's predictable patterns.

Different seasons have different weather tendencies, creating a more varied and believable climate.

Features include:

• Seasonal weather probabilities
• Continuous rain and snowfall
• Dynamic snow accumulation
• Temperature-based melting
• Snow scenery system
• Optional vanilla snow layer support

Snow no longer appears instantly when winter begins. Instead, it gradually forms and retreats with the climate.

🌾 Agriculture, Humidity & Ecology

The environment affects more than appearance.

Crop growth can depend on both season and humidity.

• Seasonal crop growth
• Humidity-based agriculture
• Greenhouse support
• Seasonal wildlife behavior
• Ecological interactions

Farming in a desert can feel completely different from farming in a temperate forest.

🍂 Seasonal Atmosphere

Ecliptic Seasons focuses heavily on atmosphere.

The seasonal timeline can drive:

• Seasonal sounds
• Ambient effects
• Particles
• Foliage colors
• Block appearance changes
• Seasonal models
• Resource-pack-driven music

Listen to birds during spring mornings.

Watch leaves drift through autumn forests.

Experience the quiet stillness of a snowy winter landscape.

🔧 Data-Driven by Design

The mod is designed around flexibility and customization.

Players, server owners, modpack creators, and resource pack authors can tailor the experience to their needs.

• Modpack-friendly design

Nearly every major feature can be adjusted through configuration files.
