Below is a nice little script to output the various formats displayed by sql server when using convert(varchar, getdate(), n).

It just outputs the current date in the various formats so you can quickly find the one your after

[csharp]
Declare @date datetime
Declare @i int
set @date = getdate()
set @i = 1

while(@i <= 31)
begin
if(@i not in (15, 16, 17, 18, 19, 22, 23, 24, 25, 28, 29))
begin
if @i < 22
print convert(varchar, @i) + ‘: ‘ + convert(varchar, @date, @i)
print convert(varchar, @i+100) + ‘: ‘ + convert(varchar, @date, @i+100)
end
set @i = @i + 1
end
[/csharp]

Hope it helps
