Can I change Month(Now) date only within MsAccess 2007 DB

[baba]

Can I change Month(Now) in Msaccess to point to someother month without changing the system date in the taskbar date/time settings of my computer.

In otherwords,is there a way to change the date/time settings to affect only MsAccess DB without affecting other documents.

I am using the below query and I want to control Month(Now) to point to a month of my choice rather than taking the system month/date.

SELECT  Table1.[StartDate],  Count(*) AS Expr1
FROM  Table1
WHERE  [StartDate]  >= dateadd("m" ,-13,DateSerial(Year(Now), Month(Now), 1) )
 And (Table1.[EndDate])<DateAdd("m",0,DateSerial(Year(Now()),Month(Now()),1))
and ( Table1.[System] = "TEST")
GROUP BY  Table1.[StartDate];

It looks like you're already doing so with the DateAdd function so I'm not sure what you mean.
