+**Web Date Warning**
+
+Provides warnings for date field entries that fall outside of a user-specified range, with the goal of reducing data entry errors.
+- For any date or date/time picker, set the threshold that should trigger the warning
+- Allows you to set a threshold for past, future or both
+- In addition to displaying warning text, will also display how many days in the past or future the selected date is
+On a record with the date or date/time picket you wish to add the warning to, edit the form view and create an inherited view. Target the field name and include the following details:
+
+
+`widget="date-warn"` if the field is a date picker
+
+`widget="datetime-warn"` if the field is a date/time picker
+
+`options="{'warn_future': 90}"` to set a threshold for future dates where 90 is the number of days
+
+And/or `options="{'warn_past': 30}"` to set a threshold for past dates where 30 is the number of days
+
+
+Example:
+
+`<field name="date_invoice" widget="date-warn" options="{'warn_future': 90, 'warn_past': 30}"/>`
