A few years back I had an app that would show a simple calendar icon in the menubar which when clicked would drop down a simple calendar of the current month. It did nothing else, but it was useful to me to be able to see a full month calendar. But it stopped working long ago. I gave up looking for a simple replacement.

A few days ago I came across Pop-Calendar from Magnesium-App. Pop-Calendar is a free utility that placed the date in a calendar icon in your menubar. When you click the icon, you can view the entire year at once or single month view (click the screenshot above for a larger view) by clicking on the month name. Pop-Calendar will remember which you view you used last, but you can switch at any time.

Pop-Calendar uses Apple’s built-in Calendar app to display all your events in either view. When you click on an individual day, you can see the day’s events. You can also add new calendar events simply by clicking a small + icon at the top of the pop-up window that appears when clicking on a day.

Pop-Calendar offers the ability to set a keyboard shortcut to show the window, as well as the ability to turn on and off individual calendars from Apple’s Calendar app. That’s all there is to it, and that’s why I love it!

Beside being free, simple to use, and easy on the eyes, it already works in Mac OS X Yosemite—though I do hope the developer adds transparency once Yosemite ships in the fall. Pop-Calendar is available directly from the developer’s site, or in the Mac App Store.
