There is no method other than has been logged in the material. As far as I m concerned is this latest update very profound if not the most profound if it comes to the destiny of mankind and our understanding of reality. There are several future dates mentioned that need to be experienced and monitored, so do that for once when these timeframes come.
This is not about prediting the future, this is about telling you what you will have to deal with and the related opportunities and threats, it all comes down eventually to our spiritual development.
