Return Value
A Date representing the date specified by the arguments
Description
Returns a Date whose value is specified by the three date components (year, month, and day).
For the function to succeed, all three components must be present, and all must be numeric values. The value returned by the function takes the short date format defined by the Regional Settings applet in the Control Panel of the client machine.
Rules at a Glance
If the value of a particular element exceeds its normal limits, DateSerial adjusts the date accordingly. For example, if you tried
DateSerial(96,2,31)
— February 31, 1996 — DateSerial returns March 2, 1996.You can specify expressions or formulas that evaluate to individual date components as parameters to DateSerial. For example,
DateSerial(98,10+9,23)
returns 23 March 1999. This makes it easier to use DateSerial to form dates whose individual elements are unknown at design time or that are created on the fly as a result of user input.
Example
Dim iYear As Integer = 1987 Dim iMonth As Integer = 3 + 11 Dim iday As Integer = 16 MsgBox(DateSerial(iYear, iMonth, iday))
