Diagram that shows a calendar of a month. The start date of work is set on the 10th of the month and the end date of work is set on the 26th. The days inbetween the start and end date, excluding Saturdays and Sundays, are highlighted in green.

There is no method to modify the lastworkdate() function for regions or scenarios that involve anything other than a work week that begins on Monday and ends on Friday.

The holiday parameter must be a string constant. It does not accept an expression.

The lastworkdate() function is commonly used as part of an expression when the user would like to calculate the proposed end date of a project or assignment, based on when the project begins and the holidays that will occur in that period.

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. For more information, see Modifying app regional settings.

Default regional settings in apps are based on a combination of identity provider settings, system settings, or browser settings. These regional format settings are not related to the language displayed in the Qlik Cloud user interface. Qlik Cloud will be displayed in the same language as the browser you are using.
