OSX Yosemite My Calendar Icon Stopped Updating Since upgrading to Yosemite, the calendar icon in my dock has been stuck on October 17. I have had no luck getting it to display the correct date.

Has anyone else run into/found a solution for this issue? Its driving me insane.
This is a little old, but for those still looking for a quick fix:

Open up the terminal and enter the following command:
'killall Dock'  

This should reload your dock, including all of the icons thus updating the date displayed in the calendar icon.
