Daylight Sunlight scattered or reflected from objects in outer space (that is, beyond the Earth's atmosphere) is not generally considered daylight. Thus, moonlight is never considered daylight, despite being indirect sunlight. Daytime is the period of time each day when daylight occurs. Daylight happens because the earth rotates and either side the sun shines on is considered daylight.

- That means it is warmer and we have summer. The declination of the Sun on the vernal equinox is 0° 00'. On the day of the vernal equinox, day and night are nearly the same amounts of time. In the United States, there are about 12 hours of daylight on this day. March is the traditional start of tornado season in the United States.

Daylight Daylight is present at a particular location, to some degree, whenever the sun is above the horizon at that location. (This is true for slightly more than 50% of the Earth at any given time. For an explanation of why it is not exactly half, see here).

Opposite Sides & Seasons On the equinox, night and day are nearly exactly the same length – 12 hours – all over the world. This is the reason it's called an “equinox”, derived from Latin, meaning equal night. However, in reality equinoxes don't have exactly 12 hours of daylight.

Dawn, dusk, sunrise, sunset and twilight As with dawn there is astronomical dusk, nautical dusk and civil dusk, occurring at 18°, 12° and 6° below the horizon respectively. Twilight is the name given to the period between dawn and sunrise, or between sunset and dusk, when light is still visible in the sky due to sunlight scattering off the atmosphere. It can also be separated in astronomical, nautical and civil sections by how far below the horizon the Sun is.

Equinox: Equal Day and Night, Almost Latitude Determines Day Length. Even if day and night aren’t exactly equal on the day of the equinox, there are days when day and night are both very close to 12 hours. However, this date depends on the latitude, and can vary by as much as several weeks from place to place.

The Seasons Remember that the tilt and direction of Earth's axis of rotation is the same as Earth revolves around the sun. On the first day of fall, Earth is neither tilted toward nor away from the sun, causing the length of daylight and nighttime hours to be equal (12 hours) in both hemispheres.

How many lumen's equal bright daylight? Split and merge into it. Answered by The Community. Making the world better, one answer at a time. The illuminance of direct sunlight is approximately 100,000 lux, but normal daylight, which is filtered through a cloudy sky, is between 5,000 and 10,000 lux, while moonlight can be as little as 0.25 lux.

When Does a Day Begin? Answer: The evening together with the morning make up the first daylight. This is a simple math equation: .5 + .5 = 1 whole daylight. Therefore the first daylight was made up of two parts, morning and evening. Morning begins at dawn and ends at noon; evening begins at noon and ends at dusk.
