How to execute wp_schedule_event event on custom time interval in wordpress

For add new time interval we need to first register it.

// Here i register for every two minutes

function add_every_two_minutes( $schedules ) {

    $schedules['every_two_minutes'] = array(

            'interval'  => 120,

            'display'   => __( 'Every 2 Minutes', 'textdomain' )

    );

     

    return $schedules;

}

add_filter( 'cron_schedules', 'add_every_two_minutes' );

Now we can use it as below

wp_schedule_event( time(), 'every_two_minutes', 'cron_function_for_execute' );
