It's written that no man knows the day or hour, but Jesus told us to recognize the season. There may well be prophecies like Israel returning as a nation, that precedes the rapture, that may identify the season, but it doesn't identify the day.
That is unlike the Mid-Trib people who believe Jesus returns 3.5 years after the 7 year peace treaty is signed. In such a case, you'd pretty accurately know when Jesus was returning, if you can spot the correct treaty being signed.
