+<h3 id="Using_DateTimeFormat">Using <code>DateTimeFormat</code></h3>
+
+<p>In basic use without specifying a locale, <code>DateTimeFormat</code> uses the default locale and default options.</p>
+
+<pre class="brush: js">var date = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));
+
+// toLocaleString without arguments depends on the implementation,
+// the default locale, and the default time zone
+console.log(new Intl.DateTimeFormat().format(date));
+// → "12/19/2012" if run with en-US locale (language) and time zone America/Los_Angeles (UTC-0800)
+</pre>
+
+<h3 id="Using_locales">Using <code>locales</code></h3>
+
+<p>This example shows some of the variations in localized date and time formats. In order to get the format of the language used in the user interface of your application, make sure to specify that language (and possibly some fallback languages) using the <code>locales</code> argument:</p>
+
+<pre class="brush: js">var date = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));
+
+// Results below use the time zone of America/Los_Angeles (UTC-0800, Pacific Standard Time)
+
+// US English uses month-day-year order
+console.log(new Intl.DateTimeFormat('en-US').format(date));
+// → "12/19/2012"
+
+// British English uses day-month-year order
+console.log(new Intl.DateTimeFormat('en-GB').format(date));
+// → "19/12/2012"
+
+// Korean uses year-month-day order
+console.log(new Intl.DateTimeFormat('ko-KR').format(date));
+// → "2012. 12. 19."
+
+// Arabic in most Arabic speaking countries uses real Arabic digits
+console.log(new Intl.DateTimeFormat('ar-EG').format(date));
+// → "١٩<span dir="rtl">‏/١٢‏/٢٠١٢</span>"
+
+// for Japanese, applications may want to use the Japanese calendar,
+// where 2012 was the year 24 of the Heisei era
+console.log(new Intl.DateTimeFormat('ja-JP-u-ca-japanese').format(date));
+// → "24/12/19"
+
+// when requesting a language that may not be supported, such as
+// Balinese, include a fallback language, in this case Indonesian
+console.log(new Intl.DateTimeFormat(['ban', 'id']).format(date));
+// → "19/12/2012"
+</pre>
+
+<h3 id="Using_options">Using <code>options</code></h3>
+
+<p>The date and time formats can be customized using the <code>options</code> argument:</p>
+
+<pre class="brush: js">var date = new Date(Date.UTC(2012, 11, 20, 3, 0, 0, 200));
+
+// request a weekday along with a long date
+var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };
+console.log(new Intl.DateTimeFormat('de-DE', options).format(date));
+// → "Donnerstag, 20. Dezember 2012"
+
+// an application may want to use UTC and make that visible
+options.timeZone = 'UTC';
+options.timeZoneName = 'short';
+console.log(new Intl.DateTimeFormat('en-US', options).format(date));
+// → "Thursday, December 20, 2012, GMT"
+
+// sometimes you want to be more precise
+options = {
+  hour: 'numeric', minute: 'numeric', second: 'numeric',
+  timeZone: 'Australia/Sydney',
+  timeZoneName: 'short'
+};
+console.log(new Intl.DateTimeFormat('en-AU', options).format(date));
+// → "2:00:00 pm AEDT"
+
+// sometimes you want to be very precise
+options.fractionalSecondDigits = 3;
+console.log(new Intl.DateTimeFormat('en-AU', options).format(date));
+// → "2:00:00.200 pm AEDT"
+
+
+// sometimes even the US needs 24-hour time
+options = {
+  year: 'numeric', month: 'numeric', day: 'numeric',
+  hour: 'numeric', minute: 'numeric', second: 'numeric',
+  hour12: false,
+  timeZone: 'America/Los_Angeles'
+};
+console.log(new Intl.DateTimeFormat('en-US', options).format(date));
+// → "12/19/2012, 19:00:00"
+
+
+// to specify options but use the browser's default locale, use 'default'
+console.log(new Intl.DateTimeFormat('default', options).format(date));
+// → "12/19/2012, 19:00:00"
+
+// sometimes it's helpful to include the period of the day
+options = {hour: "numeric", dayPeriod: "short"};
+console.log(new Intl.DateTimeFormat('en-US', options).format(date));
+// → 10 at night
+</pre>
+
+<p>The used calendar and numbering formats can also be set independently via <code>options</code> arguments:</p>
+
+<pre class="brush: js">var options = {calendar: 'chinese', numberingSystem: 'arab'};
+var dateFormat = new Intl.DateTimeFormat('default', options);
+var usedOptions = dateFormat.resolvedOptions();
+
+console.log(usedOptions.calendar);
+// → "chinese"
+
+console.log(usedOptions.numberingSystem);
+// → "arab"
+
+console.log(usedOptions.timeZone);
+// → "America/New_York" (the users default timezone)
