How to determine week no. of a given date?

For example I have a list of dates

5/11/2006, 5/18/2006, 5/25/2006

How can I categorize these dates

sample output:

Today:

5/25/2006

Last Week:

5/18/2006

I was under the impression that you wanted to determine if a given date was in the last(previous)week.

Can you kindly mark the post as an answer if it helped you

for Today,compare with DaysOfYear for Date.Now with DayeOfYear of the passed Date.Time and if 0,then today

Use this method to categorize weeks-

First time pass DateTime.Now - get week

Next time pass the date to determine-get week

(if 1 then last week)

public static int GetWeek(DateTime t)

{

int dayOfYear = t.DayOfYear;

double week = Math.Floor(dayOfYear / 7.0)+1;

return (int)week;

}

GetWeek will return the week number right what's (if 1 then last week) for
