Thanks @james you rock! That worked great. For anyone interested, I’m posting my complete code below.
<?php if( have_rows('contact_hours', 25) ): ?>
<div class="footer-hours">
<div class="footer-hours-title">Hours</div>
<?php while ( have_rows('contact_hours', 25) ) : the_row(); ?>
<?php
$begin_date = DateTime::createFromFormat('m', get_sub_field('date_range_beginning'));
$end_date = DateTime::createFromFormat('m', get_sub_field('date_range_ending'));
$current_date = (int) date('m');
$start = (int) get_sub_field('date_range_beginning');
$end = (int) get_sub_field('date_range_ending');
if ($current_date >= $start && $current_date <= $end) { ?>
<div class="footer-hour-segment">
<div class="contact-range">
<div class="contact-date-range"><?php echo $begin_date->format('F'); ?> - <?php echo $end_date->format('F'); ?></div>
<div class="contact-hour-days"><?php the_sub_field('contact_hour_days', 25); ?></div>
<div class="contact-hour-hours"><?php the_sub_field('contact_hour_hours', 25); ?></div>
</div>
</div>
<?php } ?>
<?php endwhile; ?>
</div><!--footer-hours-->
<?php endif; ?>
