Help needed to format date/time

Hi Experts,

I'm trying to format the output from the Now() function (current date and time).

I want to create a string of the form "yyyy-mm-dd".

Here's my code:
        Dim strBackupFolder As String
        'create subfolder with date and time information
        strBackupFolder = Format(Now(), "yyyy-mm-dd")

But at 2.35 pm on 1 September 2015, the output I get is "2015-35-01 02.35", not the expected "2015-09-01 02.35".

I'm running Microsoft Visual Studio Professional 2013
Version 12.0.21005.1 REL
Microsoft .NET Framework
Version 4.5.51209

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There's a difference between MMM and MM for month and mm for minutes

Thanks, codequest, for the suggestions.

"yyyy-MM-dd" gives the right format.  

("yyyy-MMM-dd" gives something like "2015-Sep-01 03.02" )
