Revelation 1:10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet, 11Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
John was instructed by Lord Jesus to write the seven letters to the seven churches.Immediately after the seven letters,he was caught up to heaven.
Revelation 4:1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.
I have done some research as in what day Lord Jesus appeared to him,and commanded him to write the seven letters.

And it has only one other occurrence in 1 Corinthians 11:20 which is referred to the Lord's supper.
The Lord's supper took place on the eve of passover.And it has been remembered since.
Was apostle John caught up to heaven on passover,the day was referred by him as the Lord's day?
And does this event has any implication to when the church will be caught up too?
