Trumpet 4: 'The fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of their light might be darkened, and a third of the day might be kept from shining, and likewise a third of the night.' 

ANTICIPATION & THINGS TO CONSIDER..

Don't forget that a math equations may not just result in concluding the final answer,  sometimes components attribute to the answer  that requires processing additional information   (including the woes and objectives prior to the actual final day).    The 4th trumpet may be an ordinary day before the 5th.

 
The final math equation at the time Jesus returns and the mountains are made flat in complete darkness, is not the same as the 4th trumpet that is different altogether.  How is the sun only covered 33%?  Isn't that an eclipse?  Don't clouds cover the sky in the day and the night alike?  Will the sun peak out of the clouds during the day as the looming clouds continue to cover the moon and stars throughout the night?  Will this occur sometimes in the prophecy test window?  If it doesn't, then this page should allow the 5th and 6th trumpets graphic funding to occur still?  Fingers crossed?!
