One of the features of HTML5 is the ability to validate most user data without relying on scripts.

This is done by using validation attributes on form elements, which allow you to specify rules for a form input like whether a value needs to be filled in, the minimum and maximum length of the data, whether it needs to be a number, an email address, or something else, and a pattern that it must match.

There have been so many problems with users not entering the date in mm/dd/yyyy, even when specifically stated on the screen.
