In Game Calendar

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

• Real-World Clock: mirrors the player's system date and time exactly
• In-Game Clock: starts from any date you choose and runs at any speed 
• (1 real second = 1 game minute, 1 game hour, 1 game day — your choice)
• Exposes Day, Month, Year, Hour, and DayOfWeek every frame
• Fires OnDayChanged and OnMonthChanged C# events
• Full public API: JumpToDate(), SetCurrentHour(), SetTime()

WallCalendar — Prop visual controller

• 6×5 grid of day cells aligned to the correct 'day column' each month
• Handles every month length and leap years automatically
• Red X marks cross off past days; today's cell is highlighted in a distinct colour
• Day number labels rendered via TextMeshPro inside each cell
• Top illustration panel driven by a 4×4 UV-sliced texture atlas
• Month name label via TextMeshPro
• Configurable Monday-first or Sunday-first week layout
• Subscribes to GameCalendar.OnDayChanged — zero Update() overhead

CalendarPageTurn — Animated month transition

• Skinned mesh page-turn animation triggered automatically on month rollover
• Animated page shows the previous month's illustration and the next month's
• Page-turn sound effect included (WallCalendarPageTurn.wav)
• Animation Event hooks for full timeline control

SunController — Demo directional light driver

• Positions a scene directional light as a sun based on the time of day
• Seasonal arc: sun elevation at noon varies across the year
