/**
 * @class
 *
 * ### Overview
 * The DateRangePicker enables the users to enter a localized date range using touch, mouse, keyboard input, or by selecting a date range in the calendar.
 *
 * ### Usage
 * The user can enter a date by:
 * Using the calendar that opens in a popup or typing it in directly in the input field (not available for mobile devices).
 * For the `ui5-daterange-picker`
 * ### ES6 Module Import
 *
 * `import "@ui5/webcomponents/dist/DateRangePicker.js";`
 *
 * ### Keyboard Handling
 * The `ui5-daterange-picker` provides advanced keyboard handling.
 *
 * When the `ui5-daterange-picker` input field is focused the user can
 * increment or decrement respectively the range start or end date, depending on where the cursor is.
 * The following shortcuts are available:
 *
 * - [Page Down] - Decrements the corresponding day of the month by one
 * - [Shift] + [Page Down] - Decrements the corresponding month by one
 * - [Shift] + [Ctrl] + [Page Down] - Decrements the corresponding year by one
 * - [Page Up] - Increments the corresponding day of the month by one
 * - [Shift] + [Page Up] - Increments the corresponding month by one
 * - [Shift] + [Ctrl] + [Page Up] - Increments the corresponding year by one
