CodePudding user response：

$firstDate = Carbon::parse('2022-09-07');
$limit = '2022-12-31';

// List dates:
foreach ($firstDate->range($limit, '2 weeks') as $date) {
  echo $date; // 2022-09-07, 2022-09-21, 2022-10-05, ...
}

// Check if days is a day off:
function isDayOff($date) {
  return ((int) Carbon::parse('2022-09-07')->diffInDays($date)) % 14 === 0;
}

if (isDayOff('2022-10-19')) {
  echo "Yes 2022-10-19 is off";
}
