Datevalue function

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).

Query examples

Expression	Results
SELECT DateValue([DateTime]) AS Expr1 FROM ProductSales;	Returns the date values of the field "DateTime" in the Short date format without the time information.

VBA example

Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.

This example uses the DateValue function to convert a string to a date. You can also use date literals to directly assign a date to a Variant or Date variable, for example, MyDate = #2/12/69#.

Dim MyDate
MyDate = DateValue("February 12, 1969")    ' Return a date.
