PerfectCalendar
A lightweight Win32 taskbar calendar designed for a seamless and efficient user experience. It runs silently in the system tray with minimal resource usage, weighing just 230 KB on disk. Built using pure C without relying on .NET or WebView2, PerfectCalendar offers a clean, no-frills approach to managing your calendar.

Key Features:

Flat-file event scheduling: Events are stored locally in a plain-text file (events.dat), giving you full ownership and control.
MCM_SETDAYSTATE bitmask highlighting: Days with events are automatically emboldened using native OS rendering, ensuring clarity without custom drawing code.
Wildcard recurring events: Supports yearly (-MM-DD) and monthly (-**-DD) recurrences for flexible scheduling.
Global hotkey: Summon the calendar instantly to your cursor with a configurable shortcut (default: Ctrl+Shift+Space).
Conflict-safe hotkey: Shows a tray notification if another app uses the same shortcut, ensuring smooth operation.
Idle fade transparency: Automatically adjusts opacity when not in use, enhancing desktop organization without distracting animations.
ISO week-number column: Displays ISO week numbers for better time tracking.
Multi-format date copy: Right-click to copy dates in ISO 8601, US, or long-form formats.
UTC clock alongside local time: Provides dual-time display for global users.
HiDPI/4K awareness: Optimized for high-resolution displays with mouse-wheel font zoom for readability.
Explorer crash resilience: Automatically re-injects the tray icon and re-registers hotkeys after Explorer restarts.

Audience & Benefit:
PerfectCalendar is ideal for users who value lightweight software without unnecessary bloat. It offers tangible benefits such as low system resource usage, complete control over event storage, and seamless integration into your taskbar experience. The calendar's design ensures it runs efficiently in the background, only appearing when needed via the global hotkey.
