I don't think I mentioned the eclipse on April 8th, but that is the start of the biblical year according to Jewish calendar which is why I mentioned it. It is also Purim based on my best interpretation of the calendar. If you want to get into why this eclipse, there are countless youtube videos that highlight fascinating relationships to geography and relative timing of other eclipses.   Bottom line, 3 eclipses in 7 years and then nothing for 20 years means either judgment to America is coming soon, or there won't be another sign for 20 years. Note that past total eclipses over the US occurred during major wars. 

The sun moon and stars were put in place for times and appointments.  There are many relationships in the pattern with past events. For example, the sequence of eclipses and the dates they fall on match exactly what happened at the time of Ester.
