Bob, The only thing I could suggest is to check the format of that cell. Press control-1 and tab and scroll to the date selection, and make sure that specific cell has the same date format as the others. I took a look at my Excel 2010, and there are several selections of formatting the date and it maybe the problem.

On a worksheet when I enter 1-5 in a date column it reads 5-Jan., which is fine. Only on one line when I enter 1-5 it reads Jan. 11, and nothing I do can stop it, regardless of what I enter in that cell. help! __________ Information from ESET NOD32 Antivirus, version of virus signature database 5765 (20110106) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
