Correct This Month and Last Month on Cost Management Blade
We are in April, but Cost Analysis shows This Month as May 2019, and Last Month as April 2019. That's the date selector in between Accumulated costs and Granularity.
Thanks for the feedback. The cost analysis date picker shows the billing period, not the calendar month. Your billing period ends in May. We’ll add an “Invoice” label when looking at a billing period to be a little more explicit and keep an eye on feedback. If needed, we can also show a more explicit date range.
