About this Mod

A networking issue has been found with this mod, causing it to send far too many updates to players on servers. I cannot fix this at the moment & thus this mod is not recommended in instances where bandwidth limits or slow internet are unavoidable!

Timekeeper is a simple mod that adds a craftable calendar into your game. The goal is to make creating a world history all that more simpler, by making it possible to actually know the precise day that it is, in a much more immersive & accessible way.

This mod also includes a Real-Time calendar for convenience, and a version compatible with Serene Seasons' 96 day year cycle. Enjoy!

Types of Calendars...
