Nepali Calendar

A modern Nepali (Bikram Sambat) calendar for Windows, built with WPF on .NET 10. It pairs a full dashboard with lightweight, always-on-top desktop widgets so the current BS date is never more than a glance away.

Features

• 📅 Bikram Sambat calendar with accurate BS↔AD conversion (verified round-trips), month/date navigation, and keyboard arrows.
• 🧩 Three desktop widgets (Small, Medium, Large) — drag to position, remembers where you put each, switches size, and refreshes at midnight.
• 🔔 System tray icon — the app lives in the tray, so closing a widget never loses it. Re-open a widget, open the calendar, or quit from the tray menu.
• 📝 Events — create, edit, and delete events (persisted locally); they appear on the dashboard, on calendar dots, and on the large widget.
• 🔄 Date converter — convert any date between BS and AD, both directions, live.
• ⬇️ Export — export your events to iCalendar (.ics) or CSV.
• 🌐 English / नेपाली — switch language anywhere; Nepali mode uses Nepali numerals.
• ⚙️ Settings — language, default widget size, and "Start with Windows".
• 🛡️ Resilient — graceful handling of out-of-range dates and a global error handler so a hiccup never takes the app down.

Requirements

• Windows 10/11
• .NET 10 SDK (to build) or the .NET 10 Desktop Runtime (to run a published build)

Running from source

git clone https://github.com/Nelessx/CalanderAppWin.git
cd CalanderAppWin
dotnet run --project CalanderAppWin

A widget appears first — right-click it (or use the tray icon) and choose Open App for the full dashboard.

Building a release

Framework-dependent (needs the .NET 10 Desktop Runtime on the target machine):

dotnet publish CalanderAppWin/NepaliCalendar.App.csproj -c Release -r win-x64 --self-contained false

Self-contained, single file (no runtime install required):

dotnet publish CalanderAppWin/NepaliCalendar.App.csproj -c Release -r win-x64 `
  --self-contained true -p:PublishSingleFile=true

The build is pinned to the .NET SDK in global.json, and every push/PR to main is built and tested by GitHub Actions.

Not yet packaged: a signed installer (MSIX/Inno), auto-update, and code signing are planned but require external accounts (a code-signing certificate, an update feed) and are not part of this repository yet.

Data range

The bundled calendar data covers BS 2081–2087 (≈ AD 2024–2031). Outside this range the app degrades gracefully rather than failing. To extend it, add rows to CalanderAppWin/Data/bs-calendar-raw.txt and regenerate the JSON.
