Time Based Events

Time based events involve different events that happen at extended intervals throughout your minecraft world. Such as blood moons (yes, direct ripoff of Terraria, but just and idea) which turn the sky red and makes mobs stronger. Things like The Ice Moon could exist, where all non-soul light sources are temporarily extinguished and mob spawning is doubled and loot is much better. The Blazing Sun, where being out in the sun too long will cause hunger and mining fatigue, but the night is bright and mob spawning is temporarily disabled. The Nether Eclipse, where the sky turns blood red and Nether Creatures can spawn in the overworld. The Dark Moon, where the only mobs that spawn are endermen. These are just a few ideas that could make extended play in the game more fun and exciting.
