C++ Calendar

AWbman (2)
I've nearly completed my C++ project to create a calendar, but am running into a small problem. After my calendar is displayed, the Saturday on the first week is always blank. I've nearly scratched my hair out trying to figure this out.

Any assistance would be appreciated.

Make day start at 0 not 1.

for (day = 0; day < daysInMonth; day++)

Then just display what you want it to look like by adding +1

cout << setw(4) << day+1;

Overall -

for (day = 0; day < daysInMonth; day++)
		{
			if ((monthStartDay + day) % 7 == 0)
				cout << endl;
			cout << setw(4) << day + 1;
		}
