Rapture - When - Two Clear Passages from Scripture

I Thessalonians 4:16-18,

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; 
then we that are alive, 

that are left, 

shall together with them be caught up in the clouds, 

to meet the Lord in the air: 

and so shall we ever be with the Lord. 
Wherefore comfort one another with these words. 

And when does the Lord ( Son of Man ) come and gather His elect?

Matthew 24:29 - 31

But immediately after the tribulation of those days 

the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 
and 

then shall appear the sign of the Son of man in heaven: 

and then shall all the tribes of the earth mourn, 

and they shall see the Son of man coming on the clouds of heaven with power and great glory. 
And he shall send forth his angels with a great sound of a trumpet, 

and they shall gather together his elect from the four winds, 

from one end of heaven to the other.
