Quickly view a calendar of the current month from the menu bar. Today's date is highlighted in the current system preference highlight color. The week starts on the day selected by the 'First day of week' system preference.
Use the left and right triangle buttons to view previous and following months. Turn the week numbers on and off with the toggle menu item.
Looks great in either light or dark mode.
To make sure Quick View Calendar runs every time you log in or restart your Mac, add it as a Login Item.
