title: How to manually trigger a cloudwatch rule with ScheduleExpression(10 days)
body: <p>I have to setup "AWS::Events::Rule" in cloudwatch with ScheduleExpression(10 days), and write some code to test it, but I can not change the "10 days" to 1 minute or call the lambda function directly. I know that we can call put event for calling a rule with EventPattern. 
  But not know how to do that for ScheduleExpression.
  Any comment is welcome, Thanks.</p>
