What format does JVdate show off? Why not use the same format for both the dates within datediff?
Code:
Select dbo.Fin_tblTransJournalVoucher.JVdate,
DATEDIFF(Day, CONVERT(datetime,dbo.Fin_tblTransJournalVoucher.JVdate,102),
CONVERT(DATETIME,'2004-02-15 00:00:00', 102)) AS Days
from dbo.Fin_tblTransJournalVoucher
Also check what format is set as default for your sql server.
Cheers!
