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