'Laravel Carbon difference in time

So I have this table with a start time and an end time and I am calculating hours. This works just fine unless the end time is midnight.

I have TIME fields in my database for start and end.

This is the calculation

      @php 
        $start = \Carbon\Carbon::parse($person->clocked_in_at);
        $end = \Carbon\Carbon::parse($person->clocked_out_at);
        $diff = $start->diff($end)->format('%H:%I');
      @endphp

If the start time is 07:30:00 and the end time is 13:00:00 it properly calculates to 05:30 hours. However if the start time is 23:30:00 and the end time is 00:00:00 which should calculate to 30 minutes, it calculates to 23:30:00

What am I missing here?

If clocked_out is less than the clocked-in then you need to factor in the date change.

      @php 
        $start = \Carbon\Carbon::parse($person->clocked_in_at);
        $end = \Carbon\Carbon::parse($person->clocked_out_at);

        @php
          if($end->lt($start) {
             $end->addDay();
          }
        @endphp

        $diff = $start->diff($end)->format('%H:%I');
      @endphp

This should also work for other cross-midnight shifts not just those that end exactly at midnight

Blade view is not the place to be doing this calculation though.

you need to add this year-month-day

like this:

    $start = \Carbon\Carbon::parse('2015-5-5 23:30:00');
    $end = \Carbon\Carbon::parse('2015-5-6 00:00:00');
    $diff = $start->diff($end)->format('%H:%I');

note: the day is begining on 00:00:00

hopefully that is help you
