On which empire does the sun never set now?

The phrase "the empire on which the sun never sets" (Spanish: el imperio donde nunca se pone el sol) was used to describe certain global empires that were so extensive that it seemed as though it was always daytime in at least one part of its territory.

The concept of an empire ruling all lands where the sun shines dates back to the ancient Egyptians, Mesopotamians, Persians, and Romans. In its modern form, it was first used for the Habsburg Empire of Charles V, who, as Duke of Burgundy, King of Spain, Archduke of Austria, and Holy Roman Emperor, attempted to build a universal monarchy. The term was then used for the Spanish Empire of Philip II of Spain and successors when the empire reached a global territorial size, particularly in the 16th, 17th and 18th centuries. It was used for the British Empire, mainly in the 19th and early 20th centuries, a period in which it reached a global territorial size. In the 20th century.
