Ok so here is my take (Could be wrong but here I go)

Maybe Me TEL U is trying to say May of the year 2015 instead of 15th day of May of some unknown year?

Maybe he left the year right there in plain sight for our eyes to see with no specific day just the month of MAY and the YEAR 2015 (next year) most activity revolves around May 2015 because the only odd ones are the Aperils...

If we follow the pattern that 15 May really means May 2015 then the Aperils will be in the years 2017 and 2027... perhaps? we shall see but it appears that everything is going right along the timeline with only about 3 more "predictions" (Cheney, Brown and the "big sickness"?) to be fulfilled before May 2015!

What do you gals and guys think? does it make any sense at all to you
