Examples
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 an Object
or Date
variable, for example, oldDate = #2/12/69#
.
Dim oldDate As Date
oldDate = DateValue("February 12, 1969")
Remarks
If StringDate
includes only numbers from 1 through 12 separated by valid date separators, DateValue
recognizes the order for month, day, and year according to the Short Date format specified for your system. DateValue
uses the current calendar setting from the CurrentCulture property of the CultureInfo class in the System.Globalization namespace. The default CurrentCulture values are determined by Control Panel settings. You can override the Short Date format by setting the ShortDatePattern property of the DateTimeFormatInfo class in the System.Globalization namespace.
DateValue
recognizes month names in long, abbreviated, and numeric 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 StringDate
is omitted, DateValue
uses the current year from your computer's system date.
If the StringDate
argument includes time information, DateValue
does not include it in the returned value. However, if StringDate
includes invalid time information, such as "89:98", an InvalidCastException error occurs.
