This is a variation on my previous Real-Time Date-Time script

A Real-Time Date-Time Script in JavaScript (ES6) - variation

Date.prototype.dayName = function() {
  const today = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
  return today[this.getDay()];
}

function time() {
  const now = new Date().toLocaleTimeString('en-GB');
  const dateNow = new Date().toLocaleDateString('en-GB', {year: 'numeric', month: 'long', day: 'numeric'});
  const todayNow = new Date().dayName();
  document.querySelector('.clock').innerHTML = `<p>Today is ${todayNow}, ${dateNow}. The current time is ${now}.</p>`;
}

setInterval(time, 1000);
