This functionality is intended to <font color="#3b9f0f">**manage the periods in which the organization will pass through a period of maintenance or blackout**</font>, then, **help in the change planning**.

## Procedure

1. Access the main menu `Processes >
    Change Management > Window of Change`;
2. The change calendar screen will be presented, where it is possible to view
   &#x20;the **periods of maintenance and blackout**;
3. To register a new window of change, click on the date you want;
4. Complete the necessary fields (**title, type, start and end date/time,
   &#x20;description of the change, recurrence of the change window**).
   There are two types of change windows:
   - **Maintenance:&#x20;**&#x75;sed to establish periods of time that changes in the
     &#x20;CI will occur;
   - **Blackout:&#x20;**&#x75;sed to establish periods of time that changes in the CI
     &#x20;will not occur.
5. Remember that the "**Global**" field should only be selected for the "**Maintenance**" type
   &#x20;of the window of change, since this field should only be used for a maintenance window
   &#x20;that does not have associated CI.
6. Click on "**Add**".
