Why is the United States called the Empire on which the sun never sets? Is it because of its geographical territory or Feng Shui?

The United States has never been called the Empire on which the sun never sets. Britain was once called the Empire on which the sun never sets.

In the British colonial era, colonies were spread all over the world, and they all belonged or basically belonged to British land. The sun would shine on British land at any time of the day, so it was called the "Empire on which the Sun Never Sets." .

With the rise of the independence movement in Asia, Africa and Latin America, various colonies have become independent one after another. The so-called "empire on which the sun never sets" is already a thing of the past, and its "prestige" is no longer there.
