Working with Change Calendar
You can use the Amazon Systems Manager console to add, manage, or delete entries in Change Calendar, a
tool in Amazon Systems Manager. You can also import events from supported third-party calendar
providers by importing an iCalendar (.ics) file that you exported
from the source calendar. And, you can use the GetCalendarState API
operation or the get-calendar-state Amazon Command Line Interface (Amazon CLI) command to get
information about the state of Change Calendar at a specific time.
