Re-scheduling a cronjob in WordPress with WP-CLI

Sometimes cronjobs are scheduled when a plugin is activated, and that time is not always the preferred time, especially when you’re running a daily event.

Using WP-CLI to list cron events

wp cron event list

It’s the wolkloos_check_weather event I was looking for.

Unschedule the event

wp cron event unschedule wolkloos_check_weather

Reschedule the event with your own time

wp cron event schedule wolkloos_check_weather 06:00 daily

Output after reschedule
