When light fall on ldr in day then the resistance of both ldr is low and when the resistance is very then the all voltage through passes the r2 droped with negative supply and no sufficient voltage goes at base terminal of transistor. The circuit works on 220v ac and if you are not accustomed to working with mains voltage or do not have ample experience in working with 220v ac mains voltage please stay away from this project.
