Question

I have a weird date rounding problem that hopefully someone can solve. My client uses a work week that runs from Monday through Sunday. Sunday’s date is considered the end of the week, and is used to identify all records entered in a particular week (so anything entered last week would have a WEEKDATE value of ’10/26/2008′, which is Sunday’s date).

One little twist is that users enter records for the previous week up until 11 AM on the Monday of the current week.

So I need a function that starts with DateTime.Now and returns the week-ending date (no time part) according to the rules above. Thanks for your help. I have a solution that works, but I’m too embarassed to post it.

Oh, and I can’t use LINQ.

Answer 1

public DateTime WeekNum(DateTime now) {     DateTime NewNow = now.AddHours(-11).AddDays(6);      return (NewNow.AddDays(- (int) NewNow.DayOfWeek).Date); }  public void Code(params string[] args) {      Console.WriteLine(WeekNum(DateTime.Now));        Console.WriteLine(WeekNum(new DateTime(2008,10,27, 10, 00, 00)));     Console.WriteLine(WeekNum(new DateTime(2008,10,27, 12, 00, 00)));     Console.WriteLine(WeekNum(new DateTime(2008,10,28)));     Console.WriteLine(WeekNum(new DateTime(2008,10,25)));   } 

You may hard-code DateTime.Now instead of passing a DateTime object. It just made testing easier this way.
