digital clock 11 - IC 4026

Concept idea

I want Digital_Clock_11 cause only play at 1.... 12. but how the concept?.. i still confuse rite now.. usually 4026 shown 0..9 How to replace the Zero? It's something weird when you say 12 hour past 30 minutes but the display shown 0:30 ????
Desain Scheme
Just search 4026 datasheet dan start make the circuit.. good luck..
Protoype
this is must be score board !!! yes.. i plan to upgrade to digital clock 4026, huummm.. need more component
