Laravel validate Time hh:mm

Use date_format rule validation

date_format:H:i

From docs

date_format:format

The field under validation must match the format defined according to the date_parse_from_format PHP function.

return Validator::make($data, [ 'appointment_date' => 'required|date_format:d-m-Y', 'from_time' => 'required|date_format:H:i', 'to_time' => 'required|date_format:H:i', ]);

This is the correct way to do time validation.

$beginHour = Carbon::parse($request['hour_begin']);
        $endHour = Carbon::parse($request['hour_end']);
        if($beginHour->addMinute()->gt($endHour)){
            return response()->json([
                'message' => 'end hour should be after than begin hour',
            ], 400);
        }

Take into account, that date_format only validates times in 24 hours format at maximum.

If you have to validate more than 24 hours you have yo use a custom regex validation.

$request->validate([
      'available_hours' => 'regex:/(\d+\:\d+)/',
]);

This rule will accept 33:00 hours, for example.
