How to execute logrotate every hour?

The 'time based'(hourly, daily, weekly, monthly) and 'size' baesd execution frequencies are available in the logrotate.. Logrotate is configurated to run daily default. There is no option to run logrotate like every 5 minutes, 30 minutes. We can configure logrotate to like every 5 minutes, 30 minutes using manualy crontab entry.
