## Amazon Systems Manager Change Calendar Events
Use the information in this topic to plan and understand the behavior of EventBridge events for Amazon Systems Manager Change Calendar.
**Note**
State changes for calendars shared from other Amazon Web Services accounts are not currently supported.
### Change Calendar integration with Amazon EventBridge
Amazon Systems Manager Change Calendar integrates with Amazon EventBridge to notify you of calendar state changes. Be aware of the following behaviors related to the underlying scheduling architecture:
Event timing and reliability
+ EventBridge delivers notifications on a best-effort basis with up to a 15-minute scheduling tolerance.
+ State change events reflect overall calendar status transitions, not individual calendar events.
+ When multiple calendar events occur simultaneously, EventBridge generates only one event per actual calendar state change.
+ EventBridge triggers events only when the calendar's overall state transitions (for example, from CLOSED to OPEN), not for individual calendar events that don't result in a state change.
+ Advisory events that don't modify the calendar state don't trigger EventBridge notifications.
Event modifications and timing considerations
+ If you modify calendar events within 15 minutes of their scheduled start or end time, EventBridge might generate duplicate notifications or miss notifications.
+ This behavior occurs because the scheduling system might not have sufficient time to properly update or cancel previously scheduled notifications.
+ For recurring events, this behavior typically affects only the first occurrence after modification.
Adjacent and overlapping events
+ When calendar events are scheduled within 5 minutes of each other, state transition events might or might not occur, depending on the actual state change.
+ Creating overlapping events in certain orders might generate additional EventBridge events even when no actual state change occurs.
+ To help ensure predictable behavior, avoid creating or modifying calendar events close to their execution times.
Best practices
+ Design your EventBridge rules and downstream automation to handle potential duplicate events.
+ Implement idempotency in your automation workflows to prevent issues from duplicate notifications.
+ Allow sufficient lead time (at least 15 minutes) when you create or modify calendar events.
+ Test your EventBridge integrations thoroughly with your specific calendar event patterns.
