Week number go crazy....

[Steph.]

When I use the "Calendar.GetWeekOfYear" function, with "fr-BE" as CultureInfo and Monday as the first day of week, I get :



Friday 31/12/2004 : week = 53

Saturday 01/01/2005 : week = 1



(see code sample here below)

That's very interesting but totally incorrect !! Friday and Saturday of the same week should have the same week number ! Except in DOTNET..



Is there any Patch for this bug ??



Thanks,



Steph.



Code sample :



CultureInfo myCI = new CultureInfo("fr-BE");

Calendar MyCal = myCI.Calendar;

CalendarWeekRule myCWR = myCI.DateTimeFormat.CalendarWeekRule;

DayOfWeek myFirstDOW = myCI.DateTimeFormat.FirstDayOfWeek;



MessageBox.Show(MyCal.GetWeekOfYear(Convert.ToDate Time("31/12/2004"), myCWR, myFirstDOW).ToString());



MessageBox.Show(MyCal.GetWeekOfYear(Convert.ToDate Time("01/01/2005"), myCWR, myFirstDOW).ToString());

Depending on what you need:

CalendarWeekRule myCWR = CalendarWeekRule.FirstFullWeek;

or

CalendarWeekRule myCWR = CalendarWeekRule.FirstFourDayWeek;
