How do I set up a time function?

Straw Hat Xephos (1)
So I started off with a simple project below. Basically I set it up so that when it was the weekends it would say "Its The Weekends!". However I'm a beginer at programming, and so I had to make it so I manually had to tell the program what day it way. I was hoping I could make it so that the program automatically grabs the time from the OS, and calculated if its the weekends or Weekdays.

	enum Days { Monday, Tuesday, Wednesday, 
		Thursday, Friday, Saturday, Sunday }; 

		
	int tmain() 
      {
          SYSTEMTIME st;
          GetSystemTime(&st);
          printf("Year:%d\nMonth:%d\nDate:%d\nHour:%d\nMin:%d\nSecond:% d\n" ,st.wYear,st.wMonth,st.wDay,st.wHour,st.wMinute,st.wSecond);
      }

	 

	if (today== Saturday || today==Sunday); 
		std::cout << "\nIts the weekends!\n";

	else 

		std::cout << "\nBack to work!\n"; 


	system("PAUSE"); 

	return 0; 

}


This is what I got from someone online, but idk how to implement it or fix the errors visual studios gives me.
