IsDate Function

Returns a Boolean value indicating whether an expression can be converted to a date.

Syntax

IsDate(expression)

The required expression argument is a Variant containing a date expression or string expression recognizable as a date or time.

Remarks

IsDate returns True if the expression is a date or is recognizable as a valid date; otherwise, it returns False. In Microsoft Windows, the range of valid dates is January 1, 100 A.D. through December 31, 9999 A.D.; the ranges vary among operating systems.

MyDate = "February 12, 1969": YourDate = #2/12/69#: NoDate = "Hello"
MyCheck = IsDate(MyDate)    ' Returns True.
MyCheck = IsDate(YourDate)    ' Returns True.
MyCheck = IsDate(NoDate)    ' Returns False.
