The end time (also called end times, end of time, end of days, last days, final days, doomsday, or eschaton) is a future described variously in the eschatologies of several world religions (both Abrahamic and non-Abrahamic), which teach that world events will reach a climax.
The Abrahamic religions maintain a linear cosmology, with end-time scenarios containing themes of transformation and redemption. In later Judaism, the term "end of days" makes reference to the Messianic Age and includes an in-gathering of the exiled Jewish diaspora, the coming of the Messiah, the resurrection of the righteous, and the world to come. Some forms of Christianity depict the end time as a period of tribulation that precedes the second coming of Christ, who will face the Antichrist along with his power structure and usher in the Kingdom of God.
History is embedded in the continuing process of samsara or the "beginningless and endless cycles of birth-death-rebirth". Buddhists believe there is an end to things but it is not final because they are bound to be born again. However, the writers of Mahayana Buddhist scriptures establish a specific end-time account in Buddhist tradition: this describes the return of Maitreya Buddha, who would bring about an end to the world. This constitutes one of the two major branches of Buddhist eschatology, with the other being the Sermon of the Seven Suns. End time in Buddhism could also involve a cultural eschatology covering "final things", which include the idea that Sakyamuni Buddha's dharma will also come to an end.
All things are impermanent, all aspects of existence are unstable and non-eternal. Beings will become so weary and disgusted with the constituent things that they will seek emancipation from them more quickly. There will come a season, O monks when, after hundreds of thousands of years, rains will cease. All seedlings, all vegetation, all plants, grasses and trees will dry up and cease to be. ...There comes another season after a great lapse of time when a second sun will appear. Now all brooks and ponds will dry up, vanish, cease to be.
The earth and all who live in it will experience the worst seven years of devastation, destruction, dispute, darkness, deception and death we have ever witness in history. The last three and half years is known as the Great Tribulation (Daniel 9:27), because how terribly things will become on earth (Matthew 24:15, 21; Revelations 13:5). The seven year tribulation period is described from Revelations 6-18. Towards the end of the Great Tribulation the Antichrist and his followers will “gathered them together to the place which in Hebrew is called Har- Magedon.” (Revelations 16) and “the beast and the kings of the earth and their armies assembled to make war against Him who sat on the horse and against His army. And the beast was seized, and with him the false prophet who performed the signs in his presence, by which he deceived those who had received the mark of the beast and those who worshiped his image; these two were thrown alive into the lake of fire which burns with brimstone. 21 And the rest were killed with the sword which came from the mouth of Him who sat on the horse, and all the birds were filled with their flesh” (Revelations 19:19-21). The Battle of Armaggeddon (mount of Meggido) is located in the valley of Jezerel in Israel. Christ will win this battle.
Another passage which indicates a post-tribulation rapture is in 2 Peter 3:10-13, where the idea of "The Day of the Lord" coming as a "thief in the night" comes from. The wicked and the spiritually unprepared people that are still alive before the return of Christ will be caught by surprise. Therefore, only God's elect will fully have a clear understanding of the timing of the second coming, and therefore Christ's coming will not catch the believers by surprise, but only those who are spiritually ignorant regarding the truth.
