# Implement change controls for Automation
<a name="automation-change-calendar-integration"></a>

By default, Automation allows you to use runbooks without date and time constraints. By integrating Automation with Change Calendar, you can implement change controls to all automations in your Amazon Web Services account. With this setting, Amazon Identity and Access Management (IAM) principals in your account can only run automations during the time periods allowed by your change calendar. To learn more about working with Change Calendar, see [Working with Change Calendar](systems-manager-change-calendar-working.md).
