history

Project history and usage

Calendar 366 II is a native macOS calendar and task application centered on a full-featured menu-bar calendar, natural-language event entry, reminders, and customizable views.

Project history

Calendar 366 II is the second major generation of Vincent Miethe's Calendar 366 application for macOS. It combines calendar events and reminders in a configurable desktop and menu-bar interface.

The current Calendar 366 product broadened the design across Apple's device platforms and added direct integrations with services including Google, Outlook, Microsoft 365, Todoist, Zoom, Fastmail, and CalDAV.

Adoption history

Calendar 366 II was distributed for macOS as both a full desktop calendar and a compact menu-bar calendar. The product subsequently evolved into a universal Calendar 366 application spanning Mac, iPhone, iPad, and Apple Watch, while the official site retained downloads for the earlier Calendar 366 II generation.

How it is used

Users view and edit events and reminders from the menu bar or desktop window, create items with natural-language input, switch among calendar sets and views, and use keyboard shortcuts or URL-scheme automation.

Calendar data can come from Apple's system database or connected calendar providers. The official privacy documentation says events and reminders remain on the device except when synchronized through a provider selected by the user.

Why package nerds care

The cask captures the second-generation standalone macOS edition from before Calendar 366 moved to its current universal Apple-platform distribution. It is representative of polished menu-bar calendar utilities that augment Apple's system calendar database without replacing the user's synchronization provider.

Timeline

  • Version 1: Calendar 366 Plus established the earlier product generation.

  • 2026: The current Calendar 366 is offered as a universal application across Mac, iPhone, iPad, and Apple Watch, with legacy Calendar 366 II downloads still referenced by the official site.
