Get events between specific date range in module controller

[MatthiasBrodelet]

I am building a module that shows the available days in the next month based on the events in the Calendar Plugin.

use Solspace\Calendar\Elements\Event;

$criteria = Event::find();
$criteria->calendarId = $calendarId;
$criteria->orderBy('startDate ASC');
$events = $criteria->all();

How can I extend this to only return start dates between a specific date range? It seems that $criteria->startDate, $criteria->start and $criteria-> dateRangeStart all don't exist.

I can of course filter them afterwards but that won't be very performant.

Edit: I just tried to to it with the GraphQL API.

{
  solspace_calendar {
    events (calendarId: 1, startDate: "2024-05-08") {
      id
      title
    }
  }
}

This returns me 0 events without issues while it should return 14 events.

{
  solspace_calendar {
    events (calendarId: 1) {
      id
      title
      startDate
    }
  }
}

This returns 17 events of which 14 have a startDate formatted as follows: 2024-05-08T14:00:00+00:00".
Of course the hour will be different per event.

At first I thought that there was an issue with the timezone but even when I query for 2024-05-07" or 2024-05-09" it just returns 0 events.
