Schedule a recurring event.

Schedules a hook which will be executed by the WordPress actions core on a specific interval, specified by you. The action will trigger when someone visits your WordPress site, if the scheduled time has passed.

Valid values for the recurrence are hourly, daily, and twicedaily. These can be extended using the {@see 'cron_schedules'} filter in wp_get_schedules().

Use wp_next_scheduled() to prevent duplicates
