Custom Dates

You can create a custom date that is binned or truncated to a specific level. The custom date becomes a new field in the Data window. Custom dates are useful if you always use a date at a specific level or you want to create calculations that rely on a binned or truncated date. Custom dates can also be created using the DATEPART and DATETRUNC functions in a calculated field. Follow the steps below to create a custom date:

1. Right-click a date field in the Data window and select Create Custom Date.
   
2. In the Create Custom Date dialog box, type a name for the custom date. For example, Date (Quarter, Year).
   
3. Select the level you want to show the date at.
   
4. Specify whether you want the custom date to be discrete Date Parts or continuous Date Values.
   
   
5. When finished, click OK.
