winget install --id=Gsasl.PerfectCalendar -eDescription
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
PerfectCalendar is available through winget as package ID Gsasl.PerfectCalendar, with version 1.3.0. Use the install command above to set it up on Windows without downloading a separate installer manually.
