Answer 1

One solution is to change

 for (i = 0,p=r; i < week_no; i++,p--)

To

 for (i = 0,p=r-week_no; i < week_no; i++,p++)

Answer 2

You can initialize p to 28 and increment it with each iteration of the loop as follows:

int r;
int p;
r=28;
for (i = 0,p=r; i < week_no; i++,p++)
{
     HoyahCalendar.a[i / 7][i % 7] = String.valueOf(p); 
}
