I'm having 2 different dates with less than 24 hours difference. When I try to get difference in days I get 0

$end = 2022-09-07 02:20:47  
$now = 2022-09-06 16:00:00 
$diffDays = $end ->diffInDays($now , false); // return 0
$diffDays = $now->diffInDays($end, false); // return 0

How to make detect that this is another day and should return diffInDays as 1 not 0

You can use diffInHours() < 24, and you can also mix it with diffInMinutes < 60. If it's either of those, then return 1. However, I would suggest dropping the absolute = false flag for doing that, as negative numbers will always hit those checks.

$end = Carbon::parse('2022-09-07 02:20:47')  ;
$now = Carbon::parse('2022-09-06 16:00:00');

// These will return 10
$diffHours = $end->diffInHours($now);
$diffHours = $now->diffInHours($end);

// These return 620
$diffMinutes = $end->diffInMinutes($now);
$diffMinutes = $now->diffInMinutes($end);

This is because method signature looks like this:

public function diffInDays(Carbon $dt = null, $abs = true)
{
    $dt = $dt ?: static::now($this->getTimezone());

    return (int) $this->diff($dt, $abs)->format('%r%a');
}

so it will round it to lower (0) if under 24 hours.

Maybe you want try floatDiffInDays instead to see different in decimal? See sample below,

echo Carbon::parse('2000-01-01 12:00')->floatDiffInDays('2000-02-11 06:00');     // 40.75
