/**
 * Retrieves supported event recurrence schedules.
 *
 * The default supported recurrences are 'hourly', 'twicedaily', 'daily', and 'weekly'.
 * A plugin may add more by hooking into the {@see 'cron_schedules'} filter.
 * The filter accepts an array of arrays. The outer array has a key that is the name
 * of the schedule, for example 'monthly'. The value is an array with two keys,
 * one is 'interval' and the other is 'display'.
 *
 * The 'interval' is a number in seconds of when the cron job should run.
 * So for 'hourly' the time is `HOUR_IN_SECONDS` (`60 * 60` or `3600`). For 'monthly',
 * the value would be `MONTH_IN_SECONDS` (`30 * 24 * 60 * 60` or `2592000`).
 *
 * The 'display' is the description. For the 'monthly' key, the 'display'
 * would be `__( 'Once Monthly' )`.
 *
 * For your plugin, you will be passed an array. You can add your
 * schedule by doing the following:
 *
 *     // Filter parameter variable name is 'array'.
 *     $array['monthly'] = array(
 *         'interval' => MONTH_IN_SECONDS,
 *         'display'  => __( 'Once Monthly' )
 *     );
 *
 * @since 2.1.0
 * @since 5.4.0 The 'weekly' schedule was added.
 *
 * @return array {
 *     The array of cron schedules keyed by the schedule name.
 *
 *     @type array ...$0 {
 *         Cron schedule information.
