This is how I ended up solving it. I know I'm a little late but I hope this saves someone a lot time and lines of code.
I used DateInterval::format to display a human readable countdown clock in years, months, and days. Check https://www.php.net/manual/en/dateinterval.format.php for the format table to see your options on how to modify your return values. Should give you what you're looking for.

$origin = new DateTime('2020-10-01');
$target = new DateTime('2020-12-25');
$interval = $origin->diff($target);
echo $interval->format('%y years, %m month, %d days until Christmas.');

Outputs: 0 years, 2 month, 24 days
