I have a bunch of raw data that I am working with. One of the columns
displays dates and I am trying to strip out the year. If I try to use the
YEAR function I get strange answers back.

For example:

Cell reads: 1/1/2006
Answer using YEAR function: 06/1905
Answer that I want: 2006

My data comes from a CSV file, so I think maybe it is in a different date
format than excel uses as a standard. Any suggestions on how to reformat
this data or some other formula I can use to get the answer I am looking for?
