All this "mod" does is inject into the TimeHelper.class of Corail Tombstone and sets the logic depending on config values. Uses a mixin to achieve this.
Default config values:
#Is Corail Tombstone april fools date logic enabled?
isAprilFoolsDayEnabled = false
#Is Corail Tombstone halloween date logic enabled?
isHalloweenEnabled = false
#Is Corail Tombstone christmas date logic enabled?
isChristmasEnabled = false
#Is Corail Tombstone easter date logic enabled?
isEasterEnabled = false
