Question

I am trying to list the next 10 weeks

The result should be like this:

Week        Year
----------------
45:         2012  
46:         2012  
47:         2012  
48:         2012  
49:         2012  
50:         2012  
51:         2012  
52:         2012  
1:          2013  
2:          2013  

some years there is a week 53, and this year the 31st of December is on a Monday, is this week 1 or week 53??

Anyways, I want to skip week 53, whenever it occours. This means that 1 or 2 days will not be a part of any week on the list, but this doesn’t matter.

Answer 1

i just wrote a small console app that does just that:

static void Main(string[] args)
    {
        System.Globalization.CultureInfo ci = System.Threading.Thread.CurrentThread.CurrentCulture;
        DateTime dt = DateTime.Now; //Use current date as starting point
        for (int i = 0; i < 10; i++)
        {

            int weekNo = ci.Calendar.GetWeekOfYear(
            dt,
            ci.DateTimeFormat.CalendarWeekRule,
            ci.DateTimeFormat.FirstDayOfWeek
             );
            int year = ci.Calendar.GetYear(dt);
            if (weekNo == 53) //if week number==53, then go to next week
            {
                dt = dt.AddDays(7);
                weekNo = ci.Calendar.GetWeekOfYear(
                dt,
                ci.DateTimeFormat.CalendarWeekRule,
                ci.DateTimeFormat.FirstDayOfWeek
                 );
                year = ci.Calendar.GetYear(dt);
            }

            dt = dt.AddDays(7);
            Console.WriteLine(weekNo + "-" + year);
        }
    }  

output today:

    46-2012
    47-2012
    48-2012
    49-2012
    50-2012
    51-2012
    52-2012
    1-2013
    2-2013
    3-2013
