Try this:

WITH qry AS
(
    SELECT a.*,
           ROW_NUMBER() OVER(ORDER BY Date) rn
      FROM MyTable a
)
SELECT a.Id,
       CASE 
        WHEN b.Id IS NULL THEN CONVERT(VARCHAR, a.Date, 101) 
        ELSE 'Label: ' + 
              CONVERT(VARCHAR, b.Date + 1, 101) + 
              ' to ' + 
              CONVERT(VARCHAR, a.Date , 101) 
       END AS Date
  FROM qry a LEFT JOIN qry b
    ON a.rn  = b.rn+1

Table Setup:

CREATE TABLE MyTable (ID INT, DATE DATETIME)
INSERT INTO MyTable VALUES(63,'07/06/2011');
INSERT INTO MyTable VALUES(64,'07/13/2011');
INSERT INTO MyTable VALUES(65,'07/20/2011');
INSERT INTO MyTable VALUES(66,'07/27/2011');
INSERT INTO MyTable VALUES(67,'08/03/2011');

Results:

Id  Date
63  07/06/2011
64  Label: 07/07/2011 to 07/13/2011
65  Label: 07/14/2011 to 07/20/2011
66  Label: 07/21/2011 to 07/27/2011
67  Label: 07/28/2011 to 08/03/2011
