week mis match

[Anonymous]

Hi All,

I am having a date column with timestamp. And when I am trying to create Week for the chart it is getting mismatched.

Ex:

DATE:12/30/2014 8:12:00 PM

When I am trying to create the week with above DATE field ,it shows as 1 week. Any ideas?

When end of Dec how it can be a first week?

Hi Ij

It is correct it should be 1, you may think its should b week 52, but this week overlaps with the first week of January 2015, as in week 52 of 2014 is combined with week 1 of 2015, therefore you will get 1. please check your calendar to verify this.

Hope this helps you.

Kind regards

The week numbers are calculated using the ISO 8601 standard. The week number for 12/30/2014 is 1. It's correct. If you want to do it differently read this blog post: Redefining the Week Numbers

Hi IJ

"

There is a definition made by the International Organization for Standardization (ISO 8601) that QlikView uses to calculate week numbers. It states that

1. The week starts on a Monday.
2. A week is always unbroken, i.e. some years week 1 starts already in December, and in other years week 52 or 53 continues into January.
3. Week 1 always contains Jan 4th. Or, differently put: Week 1 always has at least 4 days in January. A third way to say it is: The first Thursday of the year always lies in week 1."

Hello Jai,

Try the below code in your script if you don't want 2014-12-30 as your 1st week.

LOAD Dates , Div(Dates-YearStart(Dates,0,1) + WeekDay(YearStart(Dates,0,1)) +7,7) as FiscalWeek

FROM

Dates.xlsx

(ooxml, embedded labels, table is Sheet1);

Thanks and Regards,
