A "Date Input" is a user interface element that allows users to select a date from a calendar or enter it manually. It is commonly found in forms on websites and applications, enabling users to provide specific dates for events, appointments, or deadlines. This input type helps ensure that the date format is consistent and reduces errors in data entry. Typically, a date input can be displayed as a text box or a calendar pop-up. It may also include features like date pickers, which allow users to navigate through months and years easily. This functionality enhances user experience by simplifying the process of selecting dates.
