Explain the DATE Function ' DAY' in Tableau with Example?

 In Tableau, the DAY function is used to extract the day component from a given date or datetime value. It returns an integer representing the day of the month.

The syntax of the DAY function in Tableau is as follows:

DAY(date)

• date is the date or datetime value from which you want to extract the day component.

Here's an example to illustrate the usage of the DAY function in Tableau:

Suppose you have a dataset with a date field called "Order Date" containing date values. To extract the day component from the "Order Date" field, you can use the DAY function as follows:

DAY([Order Date])

In this example, the DAY function is applied to the "Order Date" field. It will return an integer representing the day component of each date value in the "Order Date" field.

The resulting output will be a column of integers representing the day of the month for each corresponding date in the "Order Date" field.

The DAY function in Tableau is useful when you need to analyze or group data based on the day of the month. You can use it to create visualizations or calculations that depend on the day component, such as analyzing sales patterns on specific days or calculating the average number of orders per day.
