I'm trying to get a list of previous months using `Carbon`.

Expected result:

```
January, February, March, April

```

What I did so far:

```
$now = Carbon::now();
$startMonth = $now->startOfMonth()->subMonth($now->month);
$currentMonth = $now->startOfMonth();
$diff = $currentMonth->diffInMonths($startMonth);

```

I've used `Carbon::now()` to get the first month of the year, then I tried to calculate the difference between the dates but I got `0`.

Also I canno find any method that returns a list of months as the expected output.
