weekend - script and chart function

This function returns a value corresponding to a timestamp of the last millisecond of the last day (Sunday) of the calendar week containing date. The default output format will be the DateFormat set in the script.


WeekEnd(date [, period_no = 0 [, first_week_day=0]])

Return data type: dual


WeekEnd arguments
Argument Description
date The date to evaluate.
period_no shift is an integer, where the value 0 indicates the week which contains date. Negative values in shift indicate preceding weeks and positive values indicate succeeding weeks.

If you don't specify first_week_day, the value of variable FirstWeekDay will be used as the first day of the week.

If you want to use another day as the first day of the week, set first_week_day to:

  • 0 for Monday
  • 1 for Tuesday
  • 2 for Wednesday
  • 3 for Thursday
  • 4 for Friday
  • 5 for Saturday
  • 6 for Sunday

The integer returned by the function will now use the first day of the week that you set with first_week_day as base (0).

Examples and results:  

These examples use the date format DD/MM/YYYY. The date format is specified in the SET DateFormat statement at the top of your load script. Change the format in the examples to suit your requirements.

Example 1:  


Returns 12/01/2013 23:59:59.

Example 2:  

weekend('10/01/2013', -1)

Returns 06/01/2013 23:59:59.

Example 3:  

weekend('10/01/2013', 0, 1)

Returns 14/01/2013 23:59:59.

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.

This example finds the final day in the week following the week of each invoice date in the table.


LOAD RecNo() as InvID, * Inline [


















WeekEnd(InvDate, 1) AS WkEnd

Resident TempTable;

Drop table TempTable;

The resulting table contains the original dates and a column with the return value of the weekend() function. You can display the full timestamp by specifying the formatting in the chart properties.
