I'm trying to get values between two dates. I have some data between dates but it returns empty.

```
$oneMonthAgo = date('Y-m-01 00:00:00', strtotime('-1 month'));
$thisMonth = date('Y-m-01 00:00:00', strtotime('0 month'));
$nextMonth = date('Y-m-01 00:00:00', strtotime('+1 month'));

$cezalar = DB::table('cezalar')
    ->where('ceza_tarih', '>=', $oneMonthAgo)
    ->where('ceza_tarih', '<', $thisMonth)
    ->get();

return $cezalar;

```
