Sharing code for a JavaScript script that displays a real-time date-time field that updates automatically, without a browser refresh.
// The purpose of this block is to list the month names which will correspond with the
// corresponding numerical value of the particular month that is other derived from
// the getDate() method.
Date.prototype.monthName = function() {
const monthsOfYear = ['January', 'February', 'March', 'April', 'May', 'June',
'July', 'August', 'September', 'October', 'November', 'December'];

// As with the previous block, this block states the days of the week so the script
// can match the named days of the week to corresponding numerical values.
Date.prototype.dayName = function() {
const daysOfWeek = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday',
'Friday', 'Saturday'];
return daysOfWeek[this.getDay()];
