Which country has the longest days

Winter begins - the days are getting longer

Status: December 21, 2020 10:52 p.m.

December 21st is the winter solstice and the beginning of the calendar year. It's the shortest day and the longest night of the year. Then the days get longer again.

Things are looking up again. December 21st was the shortest day of the year. There were only 7 hours and 28 minutes between sunrise (8.34 a.m.) and sunset (16.02 p.m.) in Hamburg. Now the days are getting longer again, even if only by a few seconds at first. At the end of January it will be light again for almost nine hours.

What happens on the shortest day?

The following applies: the more northerly the place is, the shorter the day.

The shortest day is also known as the winter solstice. In Germany - as in the entire northern hemisphere - it always falls on December 21st or 22nd. The sun is then so flat above the horizon as never before in the year. It rises late and sets again early. The following applies: the further north the place, the shorter the day. The difference between Hamburg and Munich is almost an hour, north of the Arctic Circle the sun does not rise at all.

Is it getting light earlier in the morning now?

The longer days initially have an effect in the afternoon. Until the beginning of January the sun rises a little later in the morning, but sets later in the afternoon. Reason: The earth does not run on a circular orbit around the sun, but on a slightly flattened, elliptical orbit. At the astronomical beginning of spring around March 21st, the sun rises around 6 a.m. and sets around 6 p.m.: the equinox has been reached. On June 21, 2021, summer begins and with more than 17 hours of brightness it is the longest day of the year.

Why are the days of different lengths?

Because the earth's axis is inclined, the northern hemisphere turns more towards the sun again at the winter solstice.

A little celestial science: it takes the earth a year to move around the sun once. If she were to stand upright, like hanging on a thread at the North Pole, there would be no days of different lengths. But the earth's axis, an imaginary straight line through the north and south poles, is inclined by 23.5 degrees. On the earth's orbit around the sun, the northern hemisphere for half a year and the southern hemisphere for a half year shows more towards the sun. At the winter solstice, the earth's orbit around the sun has reached the point at which the northern hemisphere again turns more towards the sun. This year it will happen on December 21st at exactly 11.02 a.m.

When does winter start?

The astronomical winter begins on the shortest day of the year. So in winter the days don't get shorter, they get longer. Meteorologists calculate differently, for them the winter started on December 1st. This makes it easier for you to evaluate your data, which is collected every month. Each of the four seasons lasts three months.

Why isn't it the coldest on the shortest day?

The blue-green earth orbits the yellow sun in an elliptical orbit.

Even if the temperatures fluctuate from year to year, the coldest day is usually January or February. Because with the flatter course of the sun, less heat reaches the earth's surface - it cools down slowly. The lowest temperatures occur with a delay before the solar radiation is again intense enough in spring to heat the earth's surface.

The fact that the earth moves on a slightly compressed, elliptical orbit around the earth is irrelevant for the temperature. In December the earth is even closer to the sun than in June.
