>I have an old FoxDos program that has to validate a person's age, i.e. someone is 18 years old or older. The original calculation does not seem to work for Y2K because of leap years. My question does Fox in all versions automatically account for leap years when calculating the number of days between two dates.

Raymond,

Yes it does. And it handles Feb 29, 2000 correctly as long as you use 4 digit years.
