Loop week based on culture info

Question

How do I loop the whole week (monday-sunday) based on culture info, so in my case monday will be the first day of the week? And is it possible to find the int value of the day at the same time?

For some information: I need to make this in order to make some generel opening hours for a store.

I think what you need is the following loop.

        DayOfWeek firstDay = CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek;
        for (int dayIndex = 0; dayIndex < 7; dayIndex++)
        {
            var currentDay = (DayOfWeek) (((int) firstDay + dayIndex) % 7);

            // Output the day
            Console.WriteLine(dayIndex + " " + currentDay);
        }

The modulo 7 is important, because the firstdayofweek can vary by different cultures.
