Showing the month on an archive page I've set up an archive page as described in the docs... so my archive page url looks something like this http://mysite.dev/news/2014/09. 

How do I then make the title display Archive for September 2014?

The {{ month }} variable is set as 09 and doing this -> {{ month|date("F") }} outputs January not September.

Any help would be appreciated.
Figured out a way to do this if anyone who has the same problem.

    {% if year is defined and month is defined %}
    {% set archiveDate = year ~ '-' ~ month ~ '-01' %}
    &lt;h2 class='archive-title'&gt;Archive for {{ archiveDate|date('F') }} - {{ year }}&lt;/h2&gt;
    {% endif %}
