Forestry has a group of bees that can only be bred at specific times of the year. This mod makes so they also can be bred at specific times of the in-game year. This pairs well with a season mod.
The default configs give the year 96 days in the form of 12 months of 8 days. Make sure this matches with your season mod. For example Serene seasons uses 7 days per month.
