Maybe 2015, but the blood moon will be the 6th seal. Seals 1-5 are pretty significant and IMHO, will be much more attention grabbing before Seal 6 comes around.
It also should be noted that with Seal 6 and Bowl Judgment 6, all unbelievers will know it is God causing those judgments, but they still will not repent, nor confess to their thievery.
IMHO, Thievery is going to increase, and probably something is going to happen to develop Babylon itself as a world trading house to further prep the stage for future events.
Also be prepared for fallen angels/demons to be loosed and cause death and destruction worldwide prior to the Blood Moon events of prophecy.
Seals 1-5 have been underway for centuries.
No one is linking that up to these seals ... at least I don’t see it here.
Look at the other events that were related ... Israel’s establishment as a nation, and Israel’s full control over Jerusalem and sovereignty over the Temple Mount.
So, if I was betting on something, I would say a major war in the Middle East, involving Israel - perhaps the “Psalm 83 War”.
