Returns a Variant (Date).
Syntax
DateValue ( date )
The required dateargument is normally a string expression representing a date from January 1, 100 through December 31, 9999. However, date can also be any expression that can represent a date, a time, or both a date and time, in that range.
Remarks
If date is a string that includes only numbers separated by valid date separators, DateValue recognizes the order for month, day, and year according to the Short Date format you specified for your system. DateValue also recognizes unambiguous dates that contain month names, either in long or abbreviated form. For example, in addition to recognizing 12/30/1991 and 12/30/91, DateValue also recognizes December 30, 1991 and Dec 30, 1991.
If the year part of date is omitted, DateValue uses the current year from your computer's system date.
If the date argument includes time information, DateValue doesn't return it. However, if date includes invalid time information (such as "89:98"), an error occurs.
Note: For date, if the Calendar property setting is Gregorian, the supplied date must be Gregorian. If the calendar is Hijri, the supplied date must be Hijri. If the supplied date is Hijri, the argument date is a String representing a date from 1/1/100 (Gregorian Aug 2, 718) through 4/3/9666 (Gregorian Dec 31, 9999).
