Metabox date month number to word

I use custom metabox with date (day, month and year). The problem is when I try to transform date number to date word – for example 10 to be October. I use this code:

function eventposttype_get_the_month_abbr($month) {
global $wp_locale;
for ( $i = 1; $i < 13; $i = $i +1 ) {
            if ( $i == $month )
                $monthabbr = $wp_locale->get_month_abbrev( $wp_locale->get_month( $i ) );
            }
return $monthabbr;
}

But now the month is displayed only with three symbols – Oct. I like to be full month name. Is there any way to define it?

Thank you in advance!

The code you are using is specifically for the month abbreviation, (Oct). You should be using this:

function eventposttype_get_the_month($month) {
global $wp_locale;
for ( $i = 1; $i < 13; $i = $i +1 ) {
            if ( $i == $month )
                $month =$wp_locale->get_month( $i ) ;
            }
return $monthabbr;
}
