Hi Sonam,
While checked your requirement we noticed that, this is similar to the keyboard functionality of the DatePicker component. While press the right arrow via keyboard then next date value of the selected date will be maintained in the focused state and while press the left arrow via keyboard then previous date value of the selected date will be maintained in the focused state. If you press the enter key, then which value in the focused state will be updated in the input of the DatePicker component.
This functionality not meets your requirement, please share the complete details of your use case and exact behavior (how to proceed the next and previous button within the calendar popup to select next and previous date value) that will help us to check and provide the solution earliest.
Regards,
Ashokkumar B.
