You can share a calendar in Change Calendar with other Amazon Web Services accounts by using the Amazon Systems Manager console. When you share a calendar, the calendar is read-only to users in the shared account. Maintenance windows, State Manager associations, and automations aren't shared.

**To share a change calendar**

1. Open the Amazon Systems Manager console at [https://console.amazonaws.cn/systems-manager/](https://console.amazonaws.cn/systems-manager/).

1. In the navigation pane, choose **Change Calendar**.

1. In the list of calendars, choose the name of the calendar that you want to share.

1. On the calendar's details page, choose the **Sharing** tab.

1. Choose **Actions, Share**.

1. In **Share calendar**, for **Account ID**, enter the ID number of a valid Amazon Web Services account, and then choose **Share**.

   Users of the shared account can read the change calendar, but they can't make changes.
