Itsycal

Itsycal is a lightweight calendar that lives in the macOS menu bar, providing quick access to dates and events without opening a full‑screen app. It syncs with the native Mac Calendar, showing existing events and allowing users to create new ones directly from the menu bar interface. The tool also supports joining virtual meetings, displaying ISO week numbers, and can replace the system clock with a customizable time display.

The application is designed for keyboard‑centric workflows, offering extensive shortcuts, Vim‑style motions, and a URL scheme for date navigation. Users can adjust visual aspects such as dark‑mode support, font size, and the number of months shown (up to two at once), as well as configure a shortcut to launch Itsycal instantly.

Itsycal is open‑source, free to use, and built on macOS 11 or newer, leveraging Sparkle for updates and MASShortcut for shortcut handling. Its minimalist design and deep integration with macOS make it suitable for users who need a compact, always‑available calendar.
