this is my Commands.CalculateMonthlyPayments.php

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use App\Models\Project;

use Carbon\Carbon;

class CalculateMonthlyPayments extends Command

    protected $signature = 'calculate:monthly-payments';
    protected $description = 'Calculate monthly payments for projects and save them in the finances table';

    public function __construct()
    {
        parent::__construct();
    }

    public function handle()
    {
        $projects = Project::with('price')->whereNotNull('paymanagir_start')->get();

        foreach ($projects as $project) {
            $paymanagirStart = Carbon::parse($project->paymanagir_start);
            $paymanagirEnd = $project->paymanagir_end ? Carbon::parse($project->paymanagir_end) : null;

            $this->calculateMonthlyPayments($project, $paymanagirStart, $paymanagirEnd);
        }
    }

    protected function calculateMonthlyPayments($project, $start, $end)
    {
        $currentDate = Carbon::now();
        $endDate = $end ? $end->copy()->endOfMonth() : $currentDate->copy()->subMonth()->endOfMonth();

        // Loop through each month from start to end date or one month before the current date
        for ($date = $start->copy()->startOfMonth(); $date->lessThanOrEqualTo($endDate); $date->addMonth()) {
            $startOfMonth = $date->copy()->startOfMonth();
            $endOfMonth = $date->copy()->endOfMonth();

            if ($date->month == $start->month && $date->year == $start->year) {
                $startOfMonth = $start;
            }

            if ($end && $date->month == $end->month && $date->year == $end->year) {
                $endOfMonth = $end;
            }

            // Only process complete months
            if ($endOfMonth->greaterThan($currentDate->subMonth()->endOfMonth())) {
                continue;
            }

            $daysInPeriod = $startOfMonth->diffInDays($endOfMonth) + 1;
            $pricePerDay = $project->price->amount / $date->daysInMonth;
            $payment = $pricePerDay * $daysInPeriod;

            Finance::create([
                'project_id' => $project->id,
                'mouth' => $date->format('F'),
                'payment' => round($payment, 2),
            ]);
        }
    }
}

and this is my routes.console.php

<?php

use Illuminate\Foundation\Inspiring;
use Illuminate\Support\Facades\Artisan;

use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
use Illuminate\Support\Facades\Schedule;
Artisan::command('inspire', function () {
    $this->comment(Inspiring::quote());
})->purpose('Display an inspiring quote')->hourly();

Schedule::command('calculate:monthly-payments')->monthlyOn(1, '00:00');

i have project which id =2 which price_id=2 whose price = 7000

I manually change the date(for testing) from the computer (currently June 22) manually set October 1

and after in command line write this php artisan calculate:monthly-payments after my finance table updating and it was designed to work like this

Pseudocode for Calculations


July:
paymanagir_start: July 22.
Days in July: 31.
Days from July 22 to July 31: 10 days.
Daily amount: 7000 / 31 ≈ 225.81.
Total amount for 10 days: 225.81 * 10 ≈ 2258.06.

August:
Full month (31 days).
Daily amount: 7000 / 31 ≈ 225.81.
Total amount for August: 225.81 * 31 = 7000.

September:
Full month (30 days).
Daily amount: 7000 / 30 ≈ 233.33.
Total amount for September: 233.33 * 30 = 7000.
October (up to October 1):

Since October 1 is the current date, we do not include October in the calculation as it is not yet completed.

and table

| **id** | **project_id** | **mouth** | **payment** | **created_at**      | **updated_at**      |
| ------ | -------------- | --------- | ----------- | ------------------- | ------------------- |
| 1      | 3              | July      | 2258.06     | 2024-07-31 00:00:00 | 2024-07-31 00:00:00 |
| 2      | 3              | August    | 7000        | 2024-08-31 00:00:00 | 2024-08-31 00:00:00 |
| 3      | 3              | September | 7000        | 2024-09-30 00:00:00 | 2024-09-30 00:00:00 |

BUT when i set date manually october 1 adn write in command line php artisan calculate:monthly-payments my finances table is like this

| id | project_id | mouth |  payment | created_at   | updated_at |
|----|--------------|-----------|--------------|-----------------|---------------------|
| 37 | 3 | July      | 3387.1  | 2024-10-01 00:45:09 | 2024-10-01 00:45:09 |
| 38 | 3 | August    | 7225.81 | 2024-10-01 00:45:09 | 2024-10-01 00:45:09 |
| 39 | 3 | September | 7233.33 | 2024-10-01 00:45:09 | 2024-10-01 00:45:09 |
| 40 | 3 | October   | 232.89  | 2024-10-01 00:45:09 | 2024-10-01 00:45:09 |
