Trying to get the month and day of the last year, and the year before the data

Here I built a query that returns the policy expiration dates from today and 11 months ago.

Since this query is retrieving data, I need to change the query to retrieve data from 1 year ago from today's date and one year before.

For example, I need policies that expire between 5/19/2013 and 5/19/2014.

I'm trying to use a function call between functions, but I'm not sure how to implement it.

This is what I have for my current data, which is displayed below:

Customer Number| Name | EMail | Producer | Policy Expired

abcde-12345-fghij-67890 | Bob Builder | somewhere@email.com | 31000 | Dora Explorer | 2014-07-29
abcde-12345-fghij-67890 | Bob Builder | somewhere@email.com | 31000 | Dora Explorer | 2014-08-07
abcde-12345-fghij-67890 | Bob Builder | somewhere@email.com | 31000 | Dora Explorer | 2014-08-10

      

        
        
        
      

    

  SELECT DISTINCT   
                Customer.custno as [Customer Number], 
                CONCAT(Customer.FirstName, ' ', Customer.LastName) AS Name, 
                Customer.EMail,
                (isnull(Employee.Firstname + ' ','') + isnull(Employee.LastName,'')) AS Producer,
                BasicPolInfo.polexpdate as [Policy Expired]

  FROM 
                Customer INNER JOIN
                BasicPolInfo ON Customer.CustId = BasicPolInfo.CustId INNER JOIN
                Transaction ON BasicPolInfo.PolId = Transaction.PolId INNER JOIN
                GeneralLedgerBranch ON Customer.GLBrnchCode = GeneralLedgerBranch.GLBrnchCode INNER JOIN
                GeneralLedgerDepartment ON Customer.GLDeptCode = GeneralLedgerDepartment.GLDeptCode INNER JOIN
                GeneralLedgerDivision ON Customer.GLDivCode = GeneralLedgerDivision.GLDivCode INNER JOIN
                Employee ON BasicPolInfo.ExecCode = Employee.EmpCode

  WHERE 
                Customer.firstname IS NOT NULL 
                AND Customer.EMail IS NOT NULL 
                AND Customer.Active = 'Y' 
                AND Customer.typecust = 'P'
                AND BasicPolInfo.PolExpDate >= DATEADD(MONTH, -10,CONVERT(VARCHAR(11),GETDATE(),106))               
                AND BasicPolInfo.PolExpDate <= CONVERT(VARCHAR(11),GETDATE(),106) 
                AND BasicPolInfo.status <> 'D'
                AND GeneralLedgerDepartment.Name = 'Personal -'

  ORDER BY      BasicPolInfo.PolExpDate ASC

      

        
        
        
      

    

Above, I am trying to translate

And BasicPolInfo.PolExpDate> = DATEADD (MONTH, -10, CONVERT (VARCHAR (11), GETDATE (), 106))
                    AND BasicPolInfo.PolExpDate <= CONVERT (VARCHAR (11), GETDATE (), 106)

Between 05/19/2013 and 05/19/2014. How can i do this?

I looked online but couldn't come to a conclusion.
