Package durations
#################

If *"week"*, *"month"* and *"year"* does not fit your requirements as a package duration, you can add your own using ``horizon_package_durations`` filter.

Example how to add *"3 days"* package duration:

.. code-block:: php
    :linenos:

    add_filter( 'horizon_package_durations', 'add_package_duration' );
    
    function add_package_duration( $package_durations ) {
        $package_durations[] = array(
            'key' => 'three_days',
            'display' => __( '3 days', 'horizon' ),
            'length' => '+3 day'
        );
        return $package_durations;
    }
   

.. warning:: Value of ``length`` attribute have to be parameter for `strtotime`_ function.
