Yes...that would be how I would define the weeks. Two things I can share. 1. Our numbering system for the weeks is YYYYWW. For week 1 of the year 2010 would be 201001.
2. I use a counter to provide a continuous numbering system. I our business, we sometimes want to look at the last 13 weeks. This may be over a time frame when you switch years. If you subtract 13 weeks from the week of 201105, you would only consider the first 5 weeks of 2011. Here is the definition I use for my date tracking table... 1 WMWeek Type : INTEGER NOT NULL WM Week 2 WkIndx Type : INTEGER NOT NULL Sequencial index for week identification 3 CompWk Type : INTEGER Comparative week for previous year. Helps when there is 53 wks 4 WMMonth Type : INTEGER WM Month - Their system is based on 4-5-4 for 13 weeks 5 WMFYr Type : TEXT 6 Their fisal year. Their fiscal year begins approx Feb 1 6 WMCYr Type : TEXT 6 The Calendar year. 7 WkBegin Type : DATE Beginning date of the week 8 WkEnd Type : DATE Ending date of the week 9 SPKWeek Type : TEXT 8 Our company's fiscal week I am sure there are other aspects you can come up with. I do find the WkIndx to be a valuable column to determine the timeframe between weeks.

I agree that consistency of the parameters is the key. I would say that what you do Gary , track the weeks as you go, is the best way to go. Would I be correct in thinking you define the weeks by dates as in: Wk start wk end week number 01/04/2009 01/11/2009 1 Etc?

I do a Year over Year looking at months so I just modified for weeks. SET VAR vCurrentYear = (IYR4(.#DATE)) SET VAR vPreviousYear = (IYR4(ADDYR(.#DATE,-1))) SET ERROR MESSAGE 677 OFF DROP VIEW CurrentYearWeeklySummary DROP VIEW LastYearWeeklySummary SET ERROR MESSAGE 677 ON CREATE TEMPORARY VIEW `CurrentYearWeeklySummary` + (Week,TotalSales) + AS SELECT + 1,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vCurrentYear AND (IWOY(InvoiceDate)) = 1 + UNION SELECT + 2,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vCurrentYear AND (IWOY(InvoiceDate)) = 2 + UNION SELECT + 3,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vCurrentYear AND (IWOY(InvoiceDate)) = 3 + UNION SELECT + 4,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vCurrentYear AND (IWOY(InvoiceDate)) = 4 CREATE TEMPORARY VIEW `LastYearWeeklySummary` + (Week,TotalSales) + AS SELECT + 1,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vPreviousYear AND (IWOY(InvoiceDate)) = 1 + UNION SELECT + 2,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vPreviousYear AND (IWOY(InvoiceDate)) = 2 + UNION SELECT + 3,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vPreviousYear AND (IWOY(InvoiceDate)) = 3 + UNION SELECT + 4,(SUM(InvoiceTotal)) FROM InvoiceHead + WHERE (IYR4(InvoiceDate))=.vPreviousYear AND (IWOY(InvoiceDate)) = 4 I only did this for four weeks so you should be able to get the gist of it. CAUTION!!! The views are created pretty fast but looking at them is slow. Another thing when I looked at it is that there are no sales in week1 for the current year. That's because the first day of the year was a Friday so the first full week begins on January 4, 2010.
