Can you give a schematic layout or a block diagram... I know i'am asking here too much, but please if you have time, can you? THX 4 d reply . . . :)

The project goes like dis.. An alarm will start to ring at 7:30a.m.(5 sec ring) and after minutes(7:35) it will ring again... This will happen every hour after 7:30(8:30..8:35..9:30..9:35...) until 12:30..12:35 After 12:35, it will ring at 1:00(same pattern above) until 8:00p.m. How can I design this project? What components will I use?
