MacCalendar
MacCalendar is a macOS menu bar calendar app for viewing dates, holidays, lunar calendar details, and your system calendar events in one place.
What is MacCalendar?
MacCalendar is a native macOS calendar app designed to keep date and schedule information accessible from the menu bar. It helps users quickly check the current date, browse months, view Chinese lunar calendar details, and see holiday and public holiday arrangements without opening a full calendar workspace. The app also works with macOS calendar data, so you can view, filter, edit, and delete system calendar events from its interface. MacCalendar includes customization options for menu bar display, calendar style, week numbers, and date or time formatting, which makes it useful for users who want a compact calendar tool that stays available throughout the day. It also offers a desktop widget workflow for users who want calendar information visible on the desktop.

Safety overview
Status: Use with caution
MacCalendar is an open source calendar utility, but its current installation method requires manually clearing macOS quarantine and opening an app that is not signed through the usual Apple developer process. That extra step is not typical for most Mac apps and means you should download it only from the publisher's official project page and avoid repackaged copies from third-party sites. Because it can read and manage your system calendar data, review what calendars you have connected before using editing features.
Recommendation: Keep MacCalendar if you actively use its menu bar calendar, lunar calendar, holiday view, or desktop widget. If you do not use it, removing it is reasonable and should only affect this app's calendar views, widget, and related settings.
