# LongDayNames

The format defined replaces the long weekday names convention in the regional settings.

Syntax:

LongDayNames

The following example of the `LongDayNames` function defines day names in full:

`Set 
 LongDayNames='Monday;Tuesday;Wednesday;Thursday;Friday;Saturday;Sunday';`

When modifying the variable, a semicolon `;` is required to separate the individual values.

The `LongDayNames` function can be used in combination with the [Date - script and chart function](https://help.qlik.com/en-US/sense/May2025/Subsystems/Hub/Content/Sense_Hub/Scripting/FormattingFunctions/Date.htm) function which returns `DayNames` as field values.

## 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.

#### Load script and results

Overview

Open the Data load editor and add the load script below to a new section.

The load script contains:

* A dataset with dates, which will be loaded into a table named, `Transactions`.

* A `date` field.

* The default `LongDayNames` definition.

Load script

```
SET LongDayNames='Monday;Tuesday;Wednesday;Thursday;Friday;Saturday;Sunday'; 
						
Transactions: 
LOAD 
date, 
Date(date,'WWWW') as dayname, 
id, 
amount 
INLINE  
[ 
date,id,amount 
01/01/2022,1,1000 
02/01/2022,2,2123 
03/01/2022,3,4124 
04/01/2022,4,2431 
]; 
```

Results

Load the data and open a sheet. Create a new table and add these fields as dimensions:

* `date`
* `dayname`

Create this measure:

`=sum(amount)`

Results table

| date | dayname | =sum(amount) |
| --- | --- | --- |
| 01/01/2022 | Saturday | 1000 |
| 02/01/2022 | Tuesday | 2123 |
| 03/01/2022 | Tuesday | 4124 |
| 04/01/2022 | Friday | 2431 |

In the load script, to create a field called, `dayname`, the `Date` function is used with the `date` field as the first argument. The second argument in the function is the formatting `WWWW`.

Using this formatting converts the values from the first argument into the corresponding full day name that is set in the variable `LongDayNames`. In the results table, the field values of our created field `dayname` display this.

#### Load script and results

Overview

Open the Data load editor and add the load script below to a new tab.

The same dataset and scenario from the first example are used. However, at the start of the script, the `LongDayNames` definition is modified to use the days of the week in Spanish.

Load Script

```
SET LongDayNames='Lunes;Martes;Miércoles;Jueves;Viernes;Sábado;Domingo'; 

Transactions: 
LOAD 
date, 
Date(date,'WWWW') as dayname, 
id, 
amount 
INLINE  
[ 
date,id,amount 
01/01/2022,1,1000 
02/01/2022,2,2123 
03/01/2022,3,4124
04/01/2022,4,2431 
]; 
```

Results

Load the data and open a sheet. Create a new table and add these fields as dimensions:

* `date`
* `dayname`

Create this measure:

`=sum(amount)`

Results table

| date | dayname | =sum(amount) |
| --- | --- | --- |
| 01/01/2022 | Sábado | 1000 |
| 02/01/2022 | Martes | 2123 |
| 03/01/2022 | Martes | 4124 |
| 04/01/2022 | Viernes | 2431 |

In the load script, the `LongDayNames` variable is modified to list the days of the week in Spanish.

Then, you create a field called, `dayname`, which is the `Date` function used with the `date` field as the first argument.

The second argument in the function is the formatting `WWWW`. By using this formatting Qlik Sense converts the values from the first argument into the corresponding full day name set in the variable `LongDayNames`.

In the results table, the field values of our created field `dayname` displays the days of the week written in Spanish and in full.
