Pegasus Calendar is an app for viewing and editing calendars and schedules from the menu bar, improving on macOS’s shortcomings in this area. All “Calendar” features can now be accessed from the menu bar. Please note that the app cannot run independently without the system’s native “Calendar” app. At the same time, because macOS cannot completely turn off the system time display, enabling Pegasus Calendar will cause two times to appear in the menu bar. You can reduce the display options in System Settings > Time and change the style to analog to make it more streamlined.
