Remove the thousand separator in a calculated column

When you use a cal­cu­lat­ed col­umn to dis­play the year instead of the com­plete date you end up with a thou­sand sep­a­ra­tor. So the year 2013 will look like 2.013 in your list view.

To remove the sep­a­ra­tor use a for­mu­la like this:   =””&YEAR([Column])
