What time does evening start?

The evening, meaning the end of the day, doesn't have a fixed time. It is defined as that period between late afternoon and night; for some that means the period of dusk, or twilight, from sundown to darkness or near-darkness.

When many people speak of the evening they think of around six pm, because that's the time the majority of people have finished their day's work.

In another sense we might say, we're spending the evening with friends, or, we ate out yesterday evening, usually referring to night rather than evening.

In English the noun, even, dates back to the Old English word, aefnung. By the 1450s, even had been replaced by evening. Today we still see uses of the term evenin words such as evensong, and eventide.

5 or 6. but really its 6

The Evening starts at 6:00pm according to some.

Depending on your perspective, evening can also start when it gets dark.

How many hours ahead is Rome from GMT London?

Rome, and the whole of Italy, is 1 hour ahead of London throughout the year.
Note: the time in the UK is only GMT in winter, it is GMT+1 hour in summer.

Both Italy and The UK have summer time, but all countries in Europe have the same rule for summer time:
Summertime starts 01:00 UTC/GMT last Sunday in March.
Summertime ends 01:00 UTC/GMT last Sunday in October.
So the time difference is the same in summer and winter.

Why doesn't the summer solstice have the earliest sunrise or latest sunset of the year?

It's due to the complicated discrepancy between our silly human clocks and the actual length of days. When measured from one solar noon—the time that the sun reaches its highest point in the sky—to the next, days around the solstices are actually about 15 seconds longer than 24 hours. But that means solar noon rarely lines up with noon on your watch, which in turn pushes the sunrise and sunset times around on the clock.

So, even though there is more daylight on the summer solstice than any other day of the year, the earliest sunrise comes before the summer solstice, and the latest sunset comes after.

What causes the different colors at sunrise and sunset?

Earth's atmosphere contains a lot of water vapor and impurities, which is the cause of the sun appearing red when it rises and sets. When the sun is overhead, the light goes through a lot less air than when you look at it on the horizon. Red light has a longer wavelength than other colors and can therefore travel farther through the atmosphere. Most of those really pretty orange skies at sunset are unfortunately caused by pollution.
White light coming from the Sun contains all colors of light from red to blue. The molecules in Earth's atmosphere do not scatter much of the red light, but they do scatter a significant amount of blue light. This effect causes the blue sky.

These molecules scattering light also cause the Sun to appear redder than it really is. When the Sun is high in the sky the amount of reddening is small. However the Sun will still appear redder from the ground than from space because the atmosphere scatters some of the blue light.

When the Sun is low in the sky, much more of the blue light coming from the Sun is scattered away from the direct path towards our eyes. Hence the Sun will appear very red when it is low in the sky.

The same thing happens to the Moon. It often appears very red when it is low in the sky for the same reason.

Much of the beauty of red sunsets or sunrises comes not from the red Sun but from the red clouds just above the western or eastern horizon. Red sunlight reflecting off these clouds gives them the same rich red color the Sun has near the horizon. So in a spectacular sunset or sunrise the entire horizon is red.

The effect can increase when the Sun sets or rises over a large city. Pollution particles increase the effect by scattering or absorbing more blue light than red light.

Enjoy your next spectacular red sunrise or sunset and remember that Rayleigh scattering off molecules in Earth's atmosphere causes the effect.

Simple

No doubt you have seen a sunrise and a sunset. The sky turns red, orange, yellow and even purple because the colored wavelengths of light travel farther through the air (atmosphere).

When the sun is low in the sky, this long journey through the atmosphere means the colors with shorter wavelengths, like blue, have already scattered or bounced off in numerous directions.

Orange sunsets (yellow and red light waves) appear when the air is clean. Sunsets that are the most spectacular occur when red wavelengths reflect off of overhead clouds.
The red and orange colors of sunset and sunrise are a result of scattering. Molecules and particles in the atmosphere alter the direction of light making it appear red, orange, and yellow.
The sun looks reddish at sunrise and sunset but not at noon because of the distance the light is traveling to reach your eye. At sunset and at noon, the light has to travel through more atmosphere before it reaches your eye and more light gets scattered before it reaches you. Since the blue part of the visible light spectrum is the highest frequency, this part of light is scattered first before it can reach you.
A sunset is more red because light is scattered due to the aerosols in the lower atmosphere. Most sunsets are red or orange due to this.

Does the sun rise in the east or the west?

The sun always rises in the East and sets in the West. Depending on the season, it may rise more or less north or south of east, and set more or less north or south of west, but there's always at least a fair component of "east" in the rising, and "west" in the setting.

Regardless of whether you are in the Northern or the Southern Hemisphere, the sun rises in the east and sets in the west. The difference between the hemispheres, however, is that in the Northern, the sun travels across the southern sky, whereas in the south, the sun travels across the northern sky.

In true point of fact, the Sun doesn't really "rise" anywhere; the Sun fundamentally remains in the middle of the solar system. The Sun APPEARS to rise, because the Earth is spinning; the Sun (and Moon, and stars, and everything else) seem to rise in the East, because the Earth is spinning from west to east. The Earth spins west-to-east once every 24 hours.

Why your shadow is longer in the evening than at midday?

Generally speaking in the middle latitudes it is because the angle of the sun is lower in the sky later in the day (in most areas, in areas with "midnight sun" type regimes this will not necessarily apply). The lower angle of the sun creates the longer shadow.
