I'm 60 years old. If I had a penny for every inaccurate chronology that I've seen in my lifetime I'd be rich man today.

The End of the Age couldn't possibly be in 2019 or 2020 because the 7 year Great Tribulation period hasn't started yet. It won't start until the world ruler signs a 7 year peace treaty with Israel.

The pre-tribulation rapture of the church will come first. I believe that before the rapture the Ezekiel 38 and 39 prophecies must be fulfilled first.
