Calendar 366 II is a macOS calendar and reminders app that helps you view schedules, manage tasks, and access upcoming events from the menu bar.
What is Calendar 366 II?
Calendar 366 II is a native macOS productivity app for managing calendars, events, and reminders from the desktop and menu bar. It is designed for people who want quicker access to their schedule than the built-in Calendar app alone, especially users who rely on multiple calendars, task lists, and day planning throughout the workday. The app supports viewing and editing events and reminders, working with calendar sets, and opening schedule information directly from widgets and menu bar views. It also includes automation support through Apple Shortcuts and a URL scheme, which can help users fit it into broader Mac workflows. Calendar 366 II is published by Nspektor and focuses on giving Mac users a compact but capable way to monitor appointments and tasks without keeping a full calendar window open all the time.

Safety overview
Status: Safe
Calendar 366 II is legitimate calendar software for macOS. Access to calendars and reminders is normal for its purpose, and optional access to contacts, location, photos, or camera can support address suggestions and event attachments. Event and reminder data is handled through your device and chosen sync providers such as iCloud, Google, or Outlook, so you should review those account permissions and only grant extra access you plan to use.
Recommendation: Keep Calendar 366 II if you use it for scheduling or reminders on your Mac. If you no longer use the app, removing it is generally fine, but you may lose its saved preferences, widgets, and convenience features until you reinstall it.
