You need to use 4 digit years as the Access help file shows that
1/1/00 through 12/31/29 is converted to 1/1/2000 through 12/31/2029
1/1/30 through 12/31/99 is converted to 1/1/1930 through 12/31/1999
Use four-digit years To ensure that Access interprets year values the way that you intended, you can type year values as four digits (for example, 2001, rather than 01).
