Calendar 366 II2.16.0

Calendar 366 II puts a full calendar in the Mac menu bar, letting you review events and reminders without leaving your current work. It creates events and tasks from natural-language text describing what, when, and where, then lets you refine them with durations, time zones, reminders, recurring schedules, locations, priorities, and notes. This gives busy users one place to turn appointments and to-dos into an organized daily plan.

Views are available in portrait and landscape, with swipes and taps for quick switching, while calendar and list sets control what appears on screen. Categories and labels color-code events and tasks, and invitations arrive in the inbox for accepting or declining while showing attendee status. Travel-time alerts update automatically according to your location and chosen mode of transport, including car, bicycle, or walking.

A single tap schedules Zoom, Google Meet, or Microsoft Teams meetings, and event links can open directly in Webex, Skype, FaceTime, and other services. Calendars stay synchronized across devices, with iPad multi-window support and Apple Watch tools for checking schedules, creating or completing entries, and deleting them; complications and widgets keep information visible. The app includes 20 home-screen and desktop widgets, six lock-screen widgets, and ten watch complications.

Light, dark, and black themes combine with nine accent choices. Siri AI understands conversational wording, extracts the title, day, and time, and adds the event to the appropriate schedule, while Calendar 366’s own natural-language engine is another option. Version 2.16.0 is freeware Productivity software for macOS on Intel and Apple Silicon, and Apple Intelligence requires iOS, iPadOS, or macOS 27.
