I have two things I wish to accomplish:

1)  Based on the current date determine the StartDate of the current Work Week  and the End Date of the current Work Week.  

2)  Based on the current date generate a list of  the prior 10 work week ranges and the upcoming 10 work week ranges.  

 I would like to implement both of these as public methods within a class.  My language of choice is C#

Thanks In Advance

It is simply math.

Assume that a week starts on Sunday and ends on SAtruday.  Then the formula is:

DateTime today = DateTime.Now.Date;
DateTime weekStart;
DateTime weekEnd;

// Calculate the start date
weekStart = today.AddDays(-((int)today.DayOfWeek));

// End date can be calculated based on adding 6 days to weekStart or manually as:
weekEnd = today.AddDays(6-((int)today.DayOfWeek));

As for the 10 work ranges, just do a loop subtracting 7 days from teh start date for each week range you want.

There is one big problem with work week calculations. Observered holidays, see :http://www.codeproject.com/dotnet/HolidayCalculator.asp for that. After that work week is trivial.

mrichmon seems to have the correct solution so please do not award any points to this comment. I just wanted to chime in and and say, this is how you do it in SQL just in case someone stumbles across this and wonders:

DECLARE @Today AS DATETIME
SET @Today = GETDATE()

SELECT DATEADD(wk, DATEDIFF(wk, 0, @Today), 0) AS Monday, DATEADD(wk, DATEDIFF(wk, 4, @Today), 4) AS Friday

Want to thank you all for you quick input.  I guess the wrinkle I failed to communicate is that I need to determine the current range on any given day.


Given today  07/12/2006 the current date range is

Work week start date 07/10/2006   work week end date  07/15/2006 - we work saturdays :-(

So basically given the current date I need to determine the date of the prior monday and the date of the upcoming saturday.

flashaoy,

It actually depends.  At least in all of the applications I have written or worked on a work week is a work week, regardless of holidays.  Now business days are a different matter.  A work week may or may not consist of 5 business days depending on holidays.

So my above is for a work week - not business days.

Very easy.  My solution is for Suday to Satruday.

If you want Monday to Satureday then simply do:

weekStart = today.AddDays(-((int)today.DayOfWeek)).AddDays(1);
weekEnd = today.AddDays(6-((int)today.DayOfWeek));
