No, and all the guess work people make is unsubstantiated. To learn more about the Anti Christ we look to Revelation 13. As for the timing of the arrival of the Anti Christ, the legitimate sign of his arrival would be the rapture.
1 Thessalonians 4:13–17
13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
1 Corinthians 15:50–54
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
This is not to suggest a timing for the rapture, as no man knows when that will happen.
30 Verily I say unto you, that this generation shall not pass, till all these things be done.
31 Heaven and earth shall pass away: but my words shall not pass away.
32 But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
33 Take ye heed, watch and pray: for ye know not when the time is.
There have been droves of people accused of being the Anti Christ over time, here are a few of note.
Emperor Nero, a notorious persecutors of the church, and his name in Hebrew can add up to 666.
Emperor Constantius, Constantius persecuted orthodox Christians and favored congregations that denied the deity of Jesus.
Pope Leo X - Martin Luther wrote a note to Pope Leo X entitled “Against the Execrable Bull of the Antichrist.” The pope did not respond positively to this missive.
Napoleon Bonaparte - In Leo Tolstoy’s novel War and Peace, Pierre turns “L’Empereur Napoleon” into a series of numbers that add up to 666.
Adolf Hitler - If you assign the value of 100 to the letter A, then 101 to the letter B, and so on, “Hitler” adds up to 666.
John F Kennedy
Henry Kissinger - Kissinger was a Middle East peacemaker of Jewish ancestry; his name in Hebrew adds up to 111, 666 divided by six.
Pope John Paul II
Ronald Wilson Reagan
Barney the Dinosaur - The claims were if you write “cute purple dinosaur” in ancient Latin characters, it becomes “CVTE PVRPLE DINOSAVR.” Extract the Roman numbers, add all the numerals together [C+V+V+L+D+I+V], and the result is 666.
Barack Obama - The day after the 2008 election, the Illinois Pick 3 lottery numbers were 666.
Bill Gates III
Many of the accusations are ridiculous on the face, but no less promulgated. The reality is Pope Francis is just one of many in the long line of those given the moniker for one reason or another. Jesus said it best..
23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
25 Behold, I have told you before.
According to biblical text, present day Christians will be long gone before the Anti Christ arrives. So if you do see him, you have a bigger problem than you know. When the Anti Christ does appear he will be the 2nd beast that is referred to in scripture. Satan always copies God, so as John the Baptist was first and prepared the way for Jesus, so will the false prophet for the Anti Christ.
“And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy”
This first beast that appears will be a Gentile not a Jew. He is the False Prophet who will become the head of the revived Roman Empire, Babylon reborn. The sea is symbolic of the size of the Gentile nation, which is to say it’s huge.
