# DatePicker Incomplete Date Validation

The Kendo UI for Angular DatePicker provides a built-in mechanism for handling incomplete dates.

By default, the incomplete date validation is disabled. To enable it, set the [`incompleteDateValidation`](https://www.telerik.com/kendo-angular-ui/components/dateinputs/api/datepickercomponent#incompletedatevalidation) property of the DatePicker to `true`.

The incomplete date validation gets activated when some, but not all, input segments contain a value—for example, `3/10/year`. The logic behind the validation is to prevent the user from accidentally leaving a non-required field partially populated.

The [`incompleteDateValidation`](https://www.telerik.com/kendo-angular-ui/components/dateinputs/api/datepickercomponent#incompletedatevalidation) setting differs from the [`required`](https://angular.dev/api/forms/RequiredValidator) one as it will not get activated when the value is completely empty—for example, `month/day/year`.
