The Day of the Lord
Throughout the Bible there are references to the coming Day of the Lord. Day can be used symbolically to reference a period in time, like the phrase "back in the day". Understanding that Scripture was written by the Holy Spirit with precision, symbols like day have precise meaning.
Prophetic references in Scripture, like day, are often self-similar or fractal and point to more than one scale of fulfillment. Similarly, day can simultaneously point to multiple time periods with differing orders of magnitude, and each magnitude is precise and not approximate. At the top-level order of magnitude, The Day of the Lord refers to the future thousand year reign of Jesus, visible bodily on earth, following the Great Tribulation, before this universe is destroyed exothermically and the New Heaven and the New Earth is created.
Peter specifically explains that a day can be a reference to 103 years:
2 Peter 3:8
But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.

A day of the trumpet and alarm against the fenced cities, and against the high towers.
