This is simple reservation system with calendar, user-defined seasons, prices (and many other rules) and reservations.
It's best to use Composer for installation, and you can also find the package on Packagist and GitHub.
To install, simply use the command:
$ composer require baraja-core/reservation
You can use the package manually by creating an instance of the internal classes, or register a DIC extension to link the services directly to the Nette Framework.
