filters – The right way to use apply_filters(‘get_calendar’) to vary get_calendar() output?

I’m utterly new in utilizing apply_filters() whereas making a theme.
I take advantage of a normal WordPress widget to show calendar.
Nevertheless i would like to vary his HTML output to get a hyperlink button to present month in sure place.
That is how I discovered the apply_filters() operate however i do not know the way to use it.

Do am i proper I can obtain the specified impact with it?

Authentic operate get_calendar() have part of code under:

if ( $subsequent ) {
    $calendar_output .= "ntt" . '<span class="wp-calendar-nav-next"><a href="' . get_month_link( $next->yr, $next->month ) . '">' . $wp_locale->get_month_abbrev( $wp_locale->get_month( $next->month ) ) . ' &raquo;</a></span>';
} else {
    $calendar_output .= "ntt" . '<span class="wp-calendar-nav-next">&nbsp;</span>';
}

What i would like is to vary else outuput to :

$calendar_output .= "ntt" . '<span class="wp-calendar-nav-next"><a href="#">My hyperlink</a></span>';

I do know that if I duplicate get_calendar() to my operate.php i will do something I need, however i need to attempt make this by utilizing any filter or hook if the WordPress provides us such risk.

Thank You upfront in your response.
