O
No it is not. There is a world of difference between (1) the Lord's Day -- the first day of the week and (2) the Day of the LORD -- the Great Tribulation followed by the Second Coming of Christ. The very fact that John said that he was "in the Spirit" on the Lord's Day and met with Christ personally should have informed you that this has nothing to do with the day of the LORD. So kindly get acquainted with the day of the LORD.
