Article Number:040214

You cannot specify a Date field as the Record title.
Fields that can be specified as the Title field

However, you can use a Calculated or Text field, which can be specified as the Record title, to display the content of a Date field as the Record title.
To do so, you need to set a formula to display the content of a Date field in a Calculated or Text field, and then specify the field as the Record title.
The detailed steps are as follows.

Steps to use a "Calculated" field

  1. Check the field code of the Date field you want to display as the Record title. Screenshot: The field code section is highlighted in the "Date settings" dialog

  2. Place a Calculated field, then click Settings from the gear-shaped Settings icon at the top right of the field. Screenshot: Navigating to "Settings" in the "Calculated" field

  3. Enter the field code of the Date field, which you have checked in Step 1, in the Formula input field.
    Select Date (Aug 06, 2012) as the display format.

Steps to use a "Text" field

To display the content of a Date field in a Text field, you need to use the "DATE_FORMAT" function.

  2. Place a Text field, then click Settings from the gear-shaped Settings icon at the top right of the field. Screenshot: Navigating to "Settings" in the "Text" field

  3. Select Calculate automatically and enter the formula.
    For example, if the field code you have checked in Step 1 is "Date", the formula is as follows:

    DATE_FORMAT(Date,"YYYY-MM-dd","Etc/GMT")
