How can I get the Month Name from Archive?

I have created an archive page.. where i wanted to display which archive month is displaying.. how can I display the month name?

If you want to get the month of the current archive page you’ll have to use single_month_title. The following code will output ” August 2014″ (notice the space before the month)

<?php single_month_title(' ') ?>

Without a space before the month:

<?php echo trim(single_month_title(' ',false)) ?>
