Dayly

A lightweight macOS menu bar calendar for Chinese public holidays.

Built with Tauri 2, React 19, TypeScript, and Vite.

Overview

Dayly is a small desktop app that lives in the macOS menu bar and opens a floating calendar window on demand. It focuses on Chinese public holidays and transfer workdays, with a simple bilingual interface in Chinese and English.

The app is designed for quick access:

• Click the tray icon to toggle the calendar window.
• The tray title shows the current date in YY-M-D星期X format.
• The window hides automatically when it loses focus.
• Launch-at-login can be toggled inside the app.

Features

• macOS menu bar app with a fixed floating window
• Monthly calendar view with today highlighting
• Chinese public holiday and transfer workday labels
• Bilingual UI: zh and en
• Launch at login support
• Transparent, always-on-top tray window
