Give your game world a living sense of time.
In-Game Calendar is a complete, ready-to-drop-in wall calendar prop system for Unity. It connects to a flexible game clock — either mirroring the player's real-world system clock or running on a fully configurable in-game time scale — and updates a detailed 3D calendar prop in real time. Days get crossed off as they pass, months flip with an animated page-turn, and the sun moves across the sky to match the time of day.
Everything ships pre-configured. Drop the prefab into your scene, press Play, and your calendar is already working.
✅ What's Included
GameCalendar — Scene singleton game clock

WallCalendar — Prop visual controller

- Top illustration panel driven by a 4×4 UV-sliced texture atlas
