Solar Day

A fundamental unit of time, established by one complete rotation of the earth on its axis as from the time the sun leaves a meridian, the highest point it attains at midday, until it returns to it. This solar or civil day is currently divided into two periods of 12 hours each. The forenoon period is indicated by Latin ante meridian (am) and the afternoon period post meridian (pm).In the Bible a day is divided up into natural periods: morning twilight or morning's darkness being the day's beginning, the rising of the sun or dawning referred as morning. Then the day's close or the time of sunset is the evening twilight or evening darkness. Recorded in the "Bible are men's expression of day to represent a measure of distance. There are times when day and night is used to mean a portion of a solar day of 24 hours. Day is used to represent a time period contemporaneous with a particular person as for example the days of Noah.The word day was also used in a flexible figurative sense example "the day of salvation." The Hebrews began their day in the evening after sunset and ended it the next day at sunset-from evening to evening. Jehovah's creative days came to be evening and there came to be morning, a first day. The Phoenicians, Numidians and Athenians reckoned a day from evening to evening. On the other hand, the Babylonians counted the day from sunrise to sunrise while Egyptians and Romans reckoned it from midnight to midnight as is commonly done today. The daylight is called day, a man's day within our solar system with its various cycles and orbits. Enjoy the sunlight and use it appropriately year after year. Solar power is a renewable energy source even in cloudy days.
