I am trying to find a simple way to get the week number for a year, given a data in the format dd/mm/yyyy (e.g. 07/01/2006). The year will not necessarily be the curent year, it could be a past or future year. (This is what's giving me the problem).

Thanks!

Try this

static int weekOfYear(DateTime dt)
{
     return (int)((int)(dt.DayOfYear + DateTime.ParseExact(dt.Year.ToString(), "yyyy", null).DayOfWeek) / 7 + 1);
}

Week is from Sunday to Saturday.

I think this can help you and show you the exact ISO way to do this:

The only thing you have to add is the parsing of the date with:

DateTime date = DateTime.ParseExact ("07/01/2006", "dd/mm/yyyy", null);
