SELECT DATEADD(MONTH, 12 * dobYear + dobMonth - 22801, dobDay - 1)

N 56°04'39.26"

for calculating age you can use logic like


CASE WHEN MONTH(dob)> MONTH(GETDATE()) 
      OR  (MONTH(dob)= MONTH(GETDATE()) AND DAY(dob)> DAY(GETDATE()))
     THEN DATEDIFF(yy,dob,GETDATE())
     ELSE DATEDIFF(yy,dob,GETDATE()) -1
END
