Dynamic Livewire calendar missing months

I am attempting to create a calendar display in which someone could choose any week start date, or year and the calendars for the year generate as required.

For the most part, things are working, but for some reason every year selected is missing 1-3 of the months, and I cannot figure out why.

Also, is there a better way to list the weekdays? I thought default php makes 0 =Sunday in which case I shouldnt need to determine current date with the now() method, but I'm not sure how else to make that happen. Here is the output: https://i.imgur.com/1uuKyGB.png

Livewire Component

<?php

namespace App\Http\Livewire;

use Carbon\Carbon;
use Livewire\Component;

class Calendar extends Component
{
    public $year='';
    public $selectedYear;
    public $date;
    public $months=12; //months to display
    public $monthFormat='F'; //m M F
    public $start_day;
    public $start_month;
    public $width=25;
    public $dayFormat ='l';//N, D l,


public function mount()
{
    $date=now();
    $this->year = $date->format('Y');
    $this->date = $date;
    $this->start_day=0;
}

public function updatedSelectedYear(){
//    $this->year=$this->selectedYear;
    $this->date=Carbon::createFromDate($this->selectedYear,$this->start_month);
//    $firstDay=$this->date->firstOfMonth()->format('N');

}
    public function updatedStartMonth(){
        $this->date=Carbon::createFromDate($this->selectedYear,$this->start_month);
        //    $firstDay=$this->date->firstOfMonth()->format('N');

    }

    public function render()
    {

        return view('livewire.calendar');
    }
}

Also how can I add some space between each calendar cause isnt doing anything with tailwindCSS- daisyUI

Thanks
