Accurate day/night-cycles Mod (B3MReload)
by krolik9833
Accurate day/night-cycles Mod (B3MReload) changes how fast the in-game day and night pass, and keeps a calendar that counts years and dates.
What it does
A time multiplier sets the speed of the day/night cycle across a wide negative-to-positive scale. Negative settings speed time up and positive settings slow it down. Mob spawning, player actions and crop growth are kept separate from this setting, so changing the cycle speed does not alter them.
A calendar runs alongside the clock. It starts at year 1000, tracks the total number of days, the current year and the day within the year, and lets a starting date be set for new worlds. An optional real-time synchronization can tie the calendar to the system clock. Seasons change according to the B3M calendar, and the mod integrates with other seasonal systems.
The mod is a NeoForge build for Minecraft 1.21.1 only. The server and every player need the mod installed. It is released under All rights reserved and is not open source. Its primary category is world generation.
Key features
Adjustable time speed
The day/night cycle can run faster or slower through a single multiplier, set in the config.
Independent game systems
Mob spawning, player actions and crop growth keep their normal timing while the cycle speed changes.
Custom calendar
Years and days are counted from a fixed starting year, giving a stable date system for the world.
Season control
Seasons follow the B3M calendar, so the time of year shifts with the calendar date instead of fixed intervals.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Long-running survival worlds
Players who want a slower or faster cycle across many in-game years can set a multiplier and keep a dated record of progress.
Roleplay and dated events
A set starting date for new worlds gives builds and events a shared timeline.
Who it’s for: Players and server owners on NeoForge 1.21.1 who want control over day length and a calendar with dates and seasons. Servers that change the multiplier need the mod on the server side as well.
