What day of the year has the shortest daylight hours?

The winter solstice (December 22) is the shortest day of the year.

Reason: Because the sun moves back and forth between the Tropic of Cancer (23 degrees 26 minutes north and south), when it is winter in the southern hemisphere, the sun shines directly on the northern hemisphere and slowly moves towards the Tropic of Cancer, and when the southern hemisphere reaches the Tropic of Cancer on the day of the winter solstice.

At this time, it can be understood that the sun is farthest from the southern hemisphere, that is, the sunshine time is short, the day is short, after that, the sun moves from the Tropic of Cancer to the Tropic of Capricorn, the sun is getting closer and closer to them, and the daylight time is getting longer and longer, so the winter solstice day is the shortest. In the same way, the summer solstice has the longest days and the shortest nights.

The shortest daylight hours of the year are on the winter solstice.

The winter solstice is the most important of the 24 solar terms. According to the Gregorian calendar, the winter solstice festival is generally on December 21-23 every year (this year is 18:44 on the 21st), this day the sun runs to the ecliptic longitude of 270 degrees, the southernmost latitude, the sun shines directly on the Tropic of Capricorn, the northern hemisphere has the shortest day, the longest night (within the Arctic Circle, 24 hours are nights), the height of the sun at noon is also the lowest, such as in Beijing, the sun height is only 26 ° 42, because the shadow of the noon of this day is the longest, so it is also called "long solstice".

Ancient China attached great importance to the winter solstice, and stipulated that the month with the winter solstice was the "sub-month", which was the first of the twelve earthly branches. The winter solstice is also a traditional festival, commonly known as the "Winter Festival", "Long Solstice Festival" and so on. Starting from the winter solstice, the days will gradually become longer, and the ancients believed that this is "the solstice of the cathode, the beginning of yang energy", so the winter solstice is regarded as the real starting point of the annual cycle, the natural luck cycle, and the growth cycle of all things.

In the hexagram representing the winter solstice, the bottom one of the six yin lines that was originally all yin has become yang, so the winter solstice is also called "one yang sheng".

Of the 365 days in a year, the summer solstice (June 22) is the longest daylight and the winter solstice (December 22) is the shortest.

On the day of the summer solstice, the sun reaches the northernmost point of the year, almost reaching the Tropic of Cancer (23°26 28 44 north latitude), and the days in the Northern Hemisphere reach the longest and longer the further north you go. It is the longest day of the year in the northern half of the blind base ball, and it is about 14 hours from sunrise to sunset in most parts of the south.

The winter solstice is the shortest day and longest night in the Northern Hemisphere. The ancients Mingzhou said that the winter solstice is: the solstice of the cathode, the beginning of the yang energy, the solstice of the south of the day, the solstice of the short day, and the solstice of the long shadow of the sun, so it is called the "winter solstice".

After the winter solstice, the climate in various places has entered the coldest stage, that is, people often say "into the nine", our people have "cold in Sanjiu, hot in Sanfu" saying.

The longest day of the year is the summer solstice, and the winter solstice is the day with the longest nights.

The summer solstice is one of the 24 solar terms, on the 21st or 22nd of June in the Gregorian calendar every year, on the day of the summer solstice, the direct sun shines on the orange hunger type near the Tropic of Capricorn, at this time, the solar altitude angle in the northern hemisphere is the largest, the shadow is the shortest in the year, and the day is the longest.

The winter solstice is the most important festival of the 24 solar terms, which takes place between December 21 and 23 of the Gregorian calendar every year. On the day of the winter solstice, the days are the shortest and the nights are the longest, but there are also some places that hold the custom of "night ninety-nine" on the day of the winter solstice to welcome the coming spring.

In the Southern Hemisphere, the day and night conditions of the winter and summer solstices are exactly the opposite of those in the Northern Hemisphere.

In the Northern Hemisphere, the summer solstice is the day with the longest daylight, on June 21 or June 22 each year, but in the Southern Hemisphere, on the contrary, that day is the shortest, and the winter solstice, which is the shortest day in the Northern Hemisphere, is the longest day in the Southern Hemisphere.
