Trouble with date format when making one range equal to another

I am using something like this to copy data from one workbook to another

Set Ws1 = Workbooks("worksheet1.xls").Sheets("Copy From")
Set Ws2 = Workbooks("worksheet2.xls").Sheets("Copy To")
Ws2.Range("A1", "K5") = Ws1.Range("A1", "K5").Value

One of my columns is a date field, formatted using Custom dd/mm/yyyy

After using this macro the date in the copied data is mm/dd/yyyy even though the receiving cell is formatted the same.... WHY?!?!?

Try this:

Ws2.Range("A1:K5").Value2 = Ws1.Range("A1:K5").Value2
