As to the end times, just my opinion, storms, earthquakes, and the likes seem to be getting stronger. Some say that the gospel has been spread to every country. I thought all that was an indicator. And they are ready to erect a new temple.
If one looks at the way a week was set up, 6 days for work, and 1 for rest, and how God see's a day as a thousand years, I think some have calculated about 6,000 years since the creation written about in genesis.
If we see, again IMO, armies massing around Isra'el, I'd think we were very close.
