A DateTime Picker is a user interface component that allows users to select a date and time easily. It typically presents a calendar view for date selection and a clock or time input for choosing the time. This tool is commonly used in applications where scheduling or time-sensitive data entry is required, such as in event planning or appointment booking. DateTime Pickers enhance user experience by minimizing errors in date and time input. They can be found in various software applications, including web forms, mobile apps, and desktop software. By providing a visual way to select dates and times, they streamline the data entry process.
