When we are developing web services or web applications, we need users to input dates sometimes. We would like users input dates in a certain format so the data can be manipulate easily. If we ask users to input dates in certain format manually, it will be very clumsy. Therefore, a good date picker or calendar is needed. Users can click on the calendar icon, a calendar will pop up and let the user choose the date. The date will be input into a specific text field after choosing a certain date from the calendar.
