The following link indicates Christ should come in the
middle of the Feast of Tabernacles.  Tabernacles
begins on the eve of September 29, the same day
Toutatis is expected to come closest to Earth.
Coincidence, or grand design; we'll have to wait and
see.

Below is just a small excerpt from this link:

"The Midst of the Feast (of Tabernacles)

John 7:14 But when it was now the midst of the feast,
Jesus went up into the temple, and began to teach.

This prophetic pattern seems to indicate that Jesus
will come in the middle of the Feast of Tabernacles of
some year. The manner of His coming will be "in
secret" (Greek: kruptos, "hidden, concealed, secret").
Paul used this word in Romans 2:29, saying, "he is a
[true] Jew who is one inwardly." He will manifest
Himself in His temple TEACHING the Word to the people.
In the old order God inhabited buildings of wood and
stone, but today He has moved and taken residence in
His people. Paul says that we are the temples of God
now (1 Cor. 3:16). Therefore, what Jesus did in His
first coming--by suddenly appearing in the temple made
of wood and stone--is not what He will do the second
time. This time He will appear, or manifest Himself,
to the world in His people, His true temple. As we
have stated earlier, the overcomers will see Him face
to face, but the rest of the people will see Him
through veils of flesh in lesser degrees of
manifestation."

Malachi 3:1 says,
1 "Behold, I am going to send My messenger, and he
will clear the way before Me. And the Lord, whom you
seek, will suddenly come to His temple; and the
messenger of the covenant, in whom you delight,
behold, He is coming," says the LORD of hosts. 2 "But
who can endure the day of His coming? And who can
stand when He appears?"
