# day Script and chart function

This function returns an integer representing the day when the fraction of the expression is interpreted as a date according to the standard number interpretation.

The function returns the day of the month for a particular date. It is commonly used to derive a day field as part of a calendar dimension.

Syntax:

day(expression)

Return data type: integer

Function examples

| Example | Result |
| --- | --- |
| `day(<br>1971-10-12 )` | returns 12 |
| `day(<br>35648 )` | returns 6, because 35648 = 1997-08-06 |

## Example 1 – DateFormat dataset (script)

#### Load script and results

Overview

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

The load script contains:

* A dataset of dates named `Master_Calendar`. The `DateFormat` system variable is set to DD/MM/YYYY.

* A preceding load that creates an additional field, named `day_of_month`, using the `day()` function.

* An additional field, named `long_date`, using the `date()` function to express the full month name.

Load script

```

SET DateFormat='DD/MM/YYYY';

Master_Calendar:
Load
        date,
        date(date,'dd-MMMM-YYYY') as long_date,
        day(date) as day_of_month
Inline

The day of the month is correctly evaluated by the `day()` function in the script.

## Example 2 – ANSI dates (script)

#### Load script and results

Overview

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

The load script contains:

* A dataset of dates named `Master_Calendar`. The DateFormat system variable DD/MM/YYYY is used. However, the dates that are included in the dataset are in ANSI standard date format.

* A preceding load that creates an additional field, named `day_of_month`, using the `date()` function.

* An additional field, named `long_date`, using the `date()` function to express the date with the full month name.

Load script

```

SET DateFormat='DD/MM/YYYY'; 
Master_Calendar: 
Load 
       date, 
       date(date,'dd-MMMM-YYYY') as long_date, 
       day(date) as day_of_month

## Example 3 – Unformatted dates (script)

[](https://help.qlik.com/en-US/sense/Subsystems/Hub/Content/Sense_Hub/Scripting/DateAndTimeFunctions/day.htm)

#### Load script and results

Overview

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

The load script contains:

* A dataset of dates named `Master_Calendar`. The`  DateFormat ` system variable DD/MM/YYYY is used.

* A preceding load that creates an additional field, named `day_of_month`, using the `day()` function.

* The original unformatted date, named `unformatted_date`.

* An additional field, named `long_date`, using the `date()` is used to convert the numerical date into a formatted date field.

Load script

```

SET DateFormat='DD/MM/YYYY'; 

Master_Calendar: 
Load 
      unformatted_date, 
      date(unformatted_date,'dd-MMMM-YYYY') as long_date, 
      day(date) as day_of_month

## Example 4 – Calculating expiry month (chart)

[](https://help.qlik.com/en-US/sense/Subsystems/Hub/Content/Sense_Hub/Scripting/DateAndTimeFunctions/day.htm)

#### Load script and chart expression

Overview

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

The load script contains:

* A dataset of orders placed in March named `Orders`. The table contains three fields:

  * id

  * order\_date

  * amount

Load script

```

Orders: 
Load 
	 id, 
	 order_date, 
	 amount 
Inline  
[ 
id,order_date,amount 
1,03/01/2022,231.24 
2,03/02/2022,567.28 
3,03/03/2022,364.28 
4,03/04/2022,575.76 
5,03/05/2022,638.68 
6,03/06/2022,785.38 
7,03/07/2022,967.46 
8,03/08/2022,287.67 
9,03/09/2022,764.45 
10,03/10/2022,875.43 
11,03/11/2022,957.35 
]; 

```

Results

Load the data and open a sheet. Create a new table and add this field as a dimension:`order_date`.

To calculate the delivery date, create this measure `=day(order_date+5)`.

Results table

| order\_date | =day(order\_date+5) |
| --- | --- |
| 03/11/2022 | 16 |
| 03/12/2022 | 17 |
| 03/13/2022 | 18 |
| 03/14/2022 | 19 |
| 03/15/2022 | 20 |
| 03/16/2022 | 21 |
| 03/17/2022 | 22 |
| 03/18/2022 | 23 |
| 03/19/2022 | 24 |
| 03/20/2022 | 25 |
| 03/21/2022 | 26 |

The `day()` function correctly determines that an order placed on the 11th of March would be delivered on the 16th based on a 5 day delivery period.
