How To Add A Date Column In Power Bi

How to Add a Date Column in Power BI

Adding a date column in Power BI can be done by manipulating existing columns or by creating a new calculated column. Here are two methods you can use:

Method 1: Manipulating Existing Columns

1. Identify a column in your data that includes date information.
2. Highlight the column in the “Fields” pane on the right side of the Power BI interface.
3. Right-click on the column and select “New Column” from the context menu.
4. In the formula bar at the top, enter the following DAX formula, replacing “YourColumnName” with the actual name of your column:

    
      DateColumn = DATE(YEAR(YourColumnName), MONTH(YourColumnName), DAY(YourColumnName))
    
  

The DAX formula creates a new column called “DateColumn” that extracts the date information from “YourColumnName”.

Method 2: Creating a New Calculated Column

1. Click on the “Modeling” tab at the top of the Power BI interface.
2. Click on the “New Column” button in the “Calculations” group.
3. In the formula bar, enter the following DAX formula, replacing “YourColumnName” with the actual name of your column:

    
      DateColumn = DATE(YEAR(YourColumnName), MONTH(YourColumnName), DAY(YourColumnName))
    
  

The DAX formula creates a new calculated column called “DateColumn” that extracts the date information from “YourColumnName”.

Once you have added the date column, you can use it in your visualizations, like any other column in your dataset.

Example:

Let’s say you have a column called “OrderDate” that includes date information in your Power BI dataset. To add a new date column:

1. Select the “OrderDate” column in the “Fields” pane.
2. Right-click on the “OrderDate” column and choose “New Column”.
3. In the formula bar, enter the following DAX formula:

    
      DateColumn = DATE(YEAR(OrderDate), MONTH(OrderDate), DAY(OrderDate))
    
  

A new column called “DateColumn” will be created in your dataset with the extracted date information from the “OrderDate” column.
