DECLARE @StartDate datetime

       ,@FirstWeek int

SET @StartDate='01 'example@sqldat.com+' 'example@sqldat.com
SET @example@sqldat.com+38
SET @FirstWeek=DATENAME(week,@StartDate)-1

;with AllDates AS

)
SELECT
    DateOf ,WeekOf ,WeekDayOf
    FROM AllDates
    WHERE example@sqldat.com AND WeekDayOf LIKE @WeekDayday+'%'
    ORDER BY DateOf
