What are Day and Hour

A Day, in astronomical terms, is defined as the time it takes for a planet to complete one full rotation on its axis relative to the Sun. A solar day on Earth is approximately 24 hours. However, a sidereal day, which measures the time relative to distant stars, is about 4 minutes shorter than a solar day due to Earth's orbit around the Sun.

An Hour is a unit of time conventionally reckoned as 1/24th of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions. The hour was initially established in the ancient Near East as 1/12 of the night or daytime. Such seasonal, temporal, or unequal hours varied by season and latitude.
