Like decades, centuries may be counted ordinally (&amp;quot;20th century&amp;quot;, &amp;quot;19th century&amp;quot;, etc.) or cardinally (&amp;quot;&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;1800s&lt;/del&gt;&amp;quot;, &amp;quot;&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;1700s&lt;/del&gt;&amp;quot;, etc.). Unlike decades, the ordinal terms are always used &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;(except informally) &lt;/del&gt;for centuries in most languages, including English.
