CalendarPop

CalendarPop is a simple app that puts Time and Date your Status Bar, just like the Mac’s default Time and Date, but with a little catch. It gives you access to a handy calendar below the time view. You can open the calendar by clicking on the date and time. It comes very helpful at times when you need to look at a calendar quickly to fix an appointment and you have it in your reach on Status Bar. You can customize the view with different time and date attributes.
