how can check number of days in a month are 28,29,30,or 31?

int GetNumberOfDays( int nYear, int nMonth )

    COleDateTime objDate;    
    int nDay = 29;
    
    for( ;nDay < 32; nDay++ )

Wouldn't this always return 31?

If you call GetStatus on a COleDateTime object constructed with the default, it will return valid

Now see it again, its 3.3

int daysOfMonth(int month, int year)

  switch( month )
  {
    case 4:
    case 6:
    case 9:
    case 11:
    return 30;
    case 2:
    return  year % 400 ? year % 100 ? year % 4 ? 28 : 29 : 28 : 29;
