In the attached XL sheet, I have a Date column that I want to sort by year. The problem is, for some of the dates, I don't know the exact day or monty, only the year, so I've put a double zero (00) placeholder in there for the days/months I'm not sure of. It needs to be exact so I can't put 01 or anything like that in there. When I do this, it does not sort correctly. Is there some way to maintain the double zeroes and have the sheet column sort correctly by year?
