Consider again the term last day.
last day of what.
There is no end like in there is a last day and then no more.
There is the Great White Throne Judgment recorded in Revelation.
That is the day the lost are judged and moved from hell into the Lake of Fire.
That is the last day there will ever be a person not born again anywhere on the planet except the lake of fire.
Then those who are born again enter into "eternity" forever with The Lord.
The last day. When Christ comes. That's the end, the final curtain.
When the Lord comes, He comes in glory to judge the quick and the dead, that's final curtain on this age.
"But each in his own order: Christ the firstfruits, then at His coming those who belong to Christ. Then comes the end, when He delivers the kingdom to God the Father after destroying every rule and every authority and power. For He must reign until He has put all His enemies under His feet. The last enemy to be destroyed is death. For 'God has put all things in subjection under His feet.' But when it says, 'all things are put in subjection,' it is plain that He is excepted who put all things in subjection under Him. When all things are subjected to Him, then the Son Himself will also be subjected to Him who put all things in subjection under Him, that God may be all in all." - 1 Corinthians 15:23-28
And for clarity concerning the final enemy to be defeated, let's move toward the end of the chapter,
"Behold! I tell you a mystery. We shall not all sleep, but we shall all be transformed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound and the dead will be raised imperishable, and we shall be transformed. For this perishable body must put on the imperishable, and this mortal body must put on immortality. When the perishable puts on the imperishable, and the mortal puts on immortality, then shall come to pass the saying that is written: 'Death is swallowed up in victory.' 'O death, where is your victory? O death, where is your sting?' The sting of death is sin, and the power of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ." - 1 Corinthians 15:51-57
When Christ comes it is to raise the dead, to deliver all things over to the Father, to judge the quick and the dead (etc). Because at this moment the dead shall be raised and transformed, and in this the final enemy--death--is destroyed.
So, last day means last day. When He comes, with trumpet blast, and the dead are raised up, it is to life immortal and everlasting, new heavens and new earth--World to Come, unto the ages of ages.
