I am relatively new to the Excel program but I have recently started using it for my job. I have 200 dates in column A and I am trying to find out which dates fall into time periods of 1/1/2008 - 1/1/2009, 1/1/2009 - 1/1/2010, 1/1/2010 - 1/1/201. Any help would be greatly appreciated, thank you for your time.
