this one helps. I have two variables, and I would like to count the hours between this variable 2020-01-16 15:20:24 and this other variable 2020-01-15 11:01:54 , try with carbon
code :
$dateStart = Carbon::parse($dateStart);
$dateEnd   = Carbon::parse($dateEnd);
$diff      = $dateStart->diffInHours($dateEnd,false);

I think the issue was by ths following , All right. Fields created_at,update_at and deleted_at are "part" of Eloquent. You use Query Builder=> inserting doesn't affect on these two fields (created_at and updated_at). You should define it manually like:
code :
$id = DB::table('widgets')
            'creator' => Auth::user()->id,
            'widget_name' => $request->input('widget_name'),
            'pages' => json_encode($request->input('pages')),
            'domain' => $request->input('domain'),
            "settings" => $settings,
            "created_at" =>  \Carbon\Carbon::now(), # new \Datetime()
            "updated_at" => \Carbon\Carbon::now(),  # new \Datetime()

Laravel: Query builder builder returning different result than actual mysql query

it helps some times You are grouping your where payment_module_id to be like %PB10____18____% or %PM10____18____% so you need to do the same in your eloquent query. This is done by using a closure.
code :
$payment_prod_failed_test = DB::table('payment_prod_pograms')
        ->where('created_at','>=','2018-09-17 00:00:00')
        ->whereRaw('char_length(payment_module_id) = 14')
        ->where(function($query) {
