Function that converts an expression into a date value.
Syntax
CDate (expression)
The expression must be a valid date. The Date data type accepts either the date or the time, or both. Possible values range from January 1, 100 to December 31, 9999.
CDate() has identical syntax to CVDate(), CVDate() returns a Variant with the subtype of Date, CDate() returns an actual Date type.
CDate cannot handle Null values, use Nz() to convert Nulls to a valid date.
Example
Dim dtmRetirement as Date
dtmRetirement = CDate("Aug 6, 2083")
dtmRetirement = CDate(Nz(Me!txtDate, #01/01/1980#))
