Function Reference/wp schedule 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. See the Plugin API for a list of hooks.


 <?php wp_schedule_event(time(), 'hourly''my_schedule_hook'$args); ?> 


(integer) (required) The first time that you want the event to occur. This must be in a UNIX timestamp format. WP cron uses UTC/GMT time, not local time. Use time(), which is always GMT in WordPress.
Default: None
(string) (required) How often the event should reoccur. Valid values:
  • hourly
  • twicedaily
  • daily
Default: None
(string) (required) The name of an action hook to execute.
Default: None
(array) (optional) Arguments to pass to the hook function(s).
Default: None


Schedule an hourly event

To schedule an hourly event in a plugin, call wp_schedule_event on activation (otherwise you will end up with a lot of scheduled events!):

register_activation_hook(__FILE__, 'my_activation');

function my_activation() {
    if (! wp_next_scheduled ( 'my_hourly_event' )) {
	wp_schedule_event(time(), 'hourly', 'my_hourly_event');

add_action('my_hourly_event', 'do_this_hourly');

function do_this_hourly() {
	// do something every hour

Don't forget to clean the scheduler on deactivation:

register_deactivation_hook(__FILE__, 'my_deactivation');

function my_deactivation() {
