Showing the month on an archive page
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 %}
