lunarweekname - script and chart function

This function returns a display value showing the year and lunar week number corresponding to a timestamp of the first millisecond of the first day of the lunar week containing date. Lunar weeks in QlikView are defined by counting 1 January as the first day of the week.


LunarWeekName(date [, period_no[, first_week_day]])

Return data type: dual


LunarWeekName arguments
Argument Description
date The date to evaluate.
period_no period_no is an integer or expression resolving to an integer, where the value 0 indicates the lunar week which contains date. Negative values in period_no indicate preceding lunar weeks and positive values indicate succeeding lunar weeks.
first_week_day An offset that may be greater than or less than zero. This changes the beginning of the year by the specified number of days and/or fractions of a day.

Example 1:  


Returns 2013/02.

Example 2:  

lunarweekname('12/01/2013', -1)

Returns 2013/01.

Example 3:  

lunarweekname('12/01/2013', 0, 1)

Returns 2013/02.

Example 4:  

Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in your document to see the result.

In this example, for each invoice date in the table, the lunar week name is created from the year in which the week lies and its associated lunar week number, shifted one week by specifying period_no as 1.
