We cannot know the day or the hour but we are to recognize the times and the season. This point, Jesus addressed to the Jews as well.
Paul emphasized this to the church.
If someone were to ask the following question:
What will the church be like in the latter days just prior to the Rapture of the Church and the rise of the antichrist?
We are given several indicators in the Word of God in which that question can be addressed.
To say They’re are no answers is an absence of understanding and an inability to assess the seasons.
There are Holy days in the Mosaic law, knowing the day or the hour is a common saying, because the months start on the first sighting of the crescent moon. So the exact time can never be known. The day can be known by the Holiday or Holy day, so you can be within a week. The years, you can know by learning the calendar and how to count like the Hebrews which we call Jews today. The season is easily known, because the certain Holy day comes in the same season every year.
To act like it can be ANY day, month, week or season is provably wrong. Study the OT, of course the plan would be there. It is inspired directly from a man who conversed with God, and wrote the books. Daniel didn’t know when it would be, but he wrote enough to show if you care to look for yourself. The first day of every month is announced by the crescent moon, not a written calendar. So estimates of the date of say Day of Atonement cannot be known until you study the signs.
