Calindock is a handy application that displays a monthly or daily calendar in Mac OS X's Dock.
Calindock brings a simple but attractive monthly or daily calendar to the Dock. There's no denying that they're strange bedfellows! Sometimes it's the odd combinations in life that bring people the most joy. Cycle through 1, 3, 6 or 12 months with the click of your mouse. Toggle between a monthly or daily calendar view. Start your week on Sunday or Monday as you prefer. Fully localized for English, Japanese, German and Spanish languages.
Please note that Calindock isn't for everyone. If you don't use the Dock's magnification feature or don't have your Dock size set somewhere near "Large" Calindock may not be a terribly useful application for you!
