This allows you to work with models that have custom date column names or when you want to analyze data based on a different date column.

## Date Column Alias

By default, laravel-trend creates a grouping select field in its database query named `date`. This can cause problems if you have a column on that table already named `date`. To avoid this conflict in the query specify a different name with `dateAlias(string $alias)` method.

Example:

```php
Trend::model(Order::class)
->dateColumn('date')
->dateAlias('date_alias')
->between(...)
->perDay()
->count();
```

This allows you to work with models that have a column named `date`.
