Hi If I open CloudWatch I have the option of Creating Schedule Snapshot. My challenge is scheduling a Snapshot once every last day of the month.

AWS Scheduler supports "L" to be used as the last day of the month. You can find it documented here - https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html
The L wildcard in the Day-of-month or Day-of-week fields specifies the last day of the month or week.
