PerfectCalendar

Gsasl · Gsasl.PerfectCalendar

Zero-bloat Win32 taskbar calendar (~230 KB). Dark mode, flat-file events, bold day highlighting, global hotkey, idle transparency.

PerfectCalendar is a pure C / Win32 API taskbar calendar that boots silently to the system tray and weighs ~230 KB on disk — no .NET, no WebView2, no background sync daemon. Key features: • Flat-file event scheduling (events.dat — plain text, always yours) • MCM_SETDAYSTATE bitmask highlighting — days with events appear bold • Wildcard recurring events: ****-12-25 (yearly), ****-**-01 (monthly) • Global hotkey (Ctrl+Shift+Space default) — summons to your cursor • Conflict-safe hotkey: shows tray notification instead of crashing • Idle fade transparency via WS_EX_LAYERED • ISO week-number column (MCS_WEEKNUMBERS) • Multi-format date copy (ISO 8601, US, long form) • UTC clock alongside local time • HiDPI / 4K aware, mouse-wheel font zoom • Explorer crash resilience (TaskbarCreated) • All settings persisted to HKCU registry
