Answer 1

This is the normal behavior, you would get the same with DatePeriod, it overflows if the day is higher than the number of days in a month, still you can easily detect this overflow comparing current day to your initial one.

But you should more likely do a simple for-loop for this, it's way less overkill:

$start_day = '2021-01-29';
$start = CarbonImmutable::parse($start_day);

$years = [];
for ($i = 0; $i < 24; $i++) {
    $date = $start->addMonthsNoOverflow($i);

    $years[$date->format("Y")][$date->format("m")]['title'] = $date->format("d n");
}
