ACalendar

ACalendar is a simple calendar app which enables access to a month-to-month calendar directly in menu bar.

With a modern layout, ACalendar enables you to: Select periods on each month aiming to temporarily underline critical occasions in each calendar view. Select different themes for the calendar. Display the date and time in Menu Bar instead of the application icon. ACalendar is a simple app intent only for replace the original date and time menu from menu bar of OS X, which doesn't have any mode for visualizing the calendar itself.
