Example diagram of weekend() function

Example diagram showing how the weekend function converts an input date into a timestamp for the last millisecond of the week in which the date occurs.

The weekend() function determines which week the date falls into. It then returns a timestamp, in date format, for the last millisecond of that week. The first day of the week is determined by the FirstWeekDay environment variable. However, this can be superseded by the first_week_day argument in the weekend() function.

Argument Description
date The date or timestamp 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.

Specifies the day on which the week starts. If omitted, the value of variable FirstWeekDay is used.

The possible values for first_week_day are 0 for Monday, 1 for Tuesday, 2 for Wednesday, 3 for Thursday, 4 for Friday, 5 for Saturday, and 6 for Sunday.

For more information about the system variable, see FirstWeekDay


If you don't specify broken_weeks, the value of variable BrokenWeeks will be used to define if weeks are broken or not.

For more information about the system variable, see BrokenWeeks

When to use it

The weekend() function is commonly used as part of an expression when the user would like the calculation to use remaining days of the week for the specified date. For example, it could be used if a user would like to calculate the total interest not yet incurred during the week.

weekend('01/10/2013') Returns 01/12/2013 23:59:59.

Regional settings

Unless otherwise specified, the examples in this topic use the following date format: MM/DD/YYYY. The date format is specified in the SET DateFormat statement in your data load script. The default date formatting may be different in your system, due to your regional settings and other factors. You can change the formats in the examples below to suit your requirements. Or you can change the formats in your load script to match these examples.

Default regional settings in apps are based on the regional system settings of the computer or server where Qlik Sense is installed. If the Qlik Sense server you are accessing is set to Sweden, the Data load editor will use Swedish regional settings for dates, time, and currency. These regional format settings are not related to the language displayed in the Qlik Sense user interface. Qlik Sense will be displayed in the same language as the browser you are using.
