title: Pikaday JS How to use full day and month names for input format without moment js
body: <p>I'm using Pikaday.js like so:</p>
  <pre><code>new Pikaday({
              field: document.getElementById('top-banner-datepicker'),
              minDate: new Date()
  </code></pre>
  <p>I know that the answer lies in this example from the documentation:</p>
  <pre><code>var picker = new Pikaday({
      field: document.getElementById('datepicker'),
      format: 'D/M/YYYY',
      toString(date, format) {
          // you should do formatting based on the passed format,
          // but we will just return 'D/M/YYYY' for simplicity
          const day = date.getDate();
          const month = date.getMonth() + 1;
          const year = date.getFullYear();
          return `${day}/${month}/${year}`;
      },
      parse(dateString, format) {
          // dateString is the result of `toString` method
          const parts = dateString.split('/');
          const day = parseInt(parts[0], 10);
          const month = parseInt(parts[1], 10) - 1;
          const year = parseInt(parts[2], 10);
          return new Date(year, month, day);
      }
  });
  </code></pre>
  <p>But I can't figure out how to use full day (Monday, Tuesday, Wednesday, etc) and full month names (January, February, etc) instead of the abbreviations (Mon, Tue, Wed... Jan, Feb, Mar... etc)</p>
  <p>I don't want to use Moment.JS as it's a giant dependency.</p>
  <p>Any help much appreciated!</p>
  <p>Thank you</p>
