The document discusses a JavaScript function that calculates the difference between two dates and times entered by a user. It first validates that the dates and times are in the proper format. It then converts the dates and times to Date objects, calculates the difference between them in milliseconds, and breaks that down into weeks, days, hours, minutes and seconds to display to the user. The function returns false so the form it is used in will not submit.
