error 'DAYOFWEEK' is not a recognized built-in function name.

hi friend 
I used the following query with sql server 2008 to select group by records

SELECT
    sum(ljoin)as lct,
    sum(rjoin)as rct,
CONCAT(DATE_FORMAT(DATE_ADD(date, INTERVAL(1-DAYOFWEEK(date)) DAY),'%Y-%m-%e'),' TO ',
DATE_FORMAT(DATE_ADD(date, INTERVAL(7-DAYOFWEEK(date)) DAY),'%Y-%m-%e'))AS DateRangeFROM Pairs_Details WHERE userid='jitu'GROUPBY YEARWEEK(date)

it return the  following error 'DAYOFWEEK' is not a recognized built-in function name.

But I can not get my desire result there are my following table, data and desire output which I want

Pairs_Details table definition:

CREATETABLE[dbo].[Pairs_Details]([sno][int]IDENTITY(1,1)NOTNULL,[userid][nvarchar](50)NULL,[date][datetime]NULL,[ljoin][int]NULL,[rjoin][int]NULL)ON[PRIMARY]

Example data:

    sno     userid         date                             ljoin   rjoin1       jitu           2014-01-2115:48:24.0001NULL2       jitu           2014-01-2215:48:24.000NULL13       tetu1234       2014-01-2215:48:24.0001NULL4       jitu           2014-01-2415:48:24.000NULL15       saurbh123      2014-01-2515:48:24.0001NULL6       jitu           2014-01-2615:48:24.0001NULL7       tetu1234       2014-01-2816:40:05.000NULL18       jitu           2014-01-2816:40:05.000NULL1
