Meaning and Usage

An apparent solar day refers to the time it takes for the Sun to return to its highest point in the sky, measured by the position of the Sun at local noon to the next local noon.

Etymology

The term "apparent" originates from Middle French "apparent" which means "visible, clear, or conspicuous," and ultimately derives from Latin "apparens," the present participle of "apparere," meaning "to appear." "Solar" traces back to the Latin word "solaris," pertaining to the Sun. "Day" comes from Old English "dæg," which has cognates in many Germanic languages, signifying a period of light defined by the position of the Sun.
