Google Doodle reminds you of the Spring Equality Day of 2019

From the eastern point of view, Spring equinox is at mid-spring.

What is Spring Day?

Spring day is the day when the daytime and night time are equal at the equator. From the eastern point of view, Spring equinox is in the middle of spring. However, according to Western science, this is the beginning of spring in the northern hemisphere or the beginning of autumn in the southern hemisphere.

Google Doodle icon today 20/3.

In the southern hemisphere, this day is Fall day. On this day, the Sun will rise from the horizon in exactly the east direction, and dive down to the horizon in exactly the west. In addition, the Sun will lie straight on top of the head at noon.
Spring Day is considered a festival day in many parts of the world.

Norouz festival (New Year's festival or early spring festival) of Iran is held on this day. The Bahai religion calls this ceremony Naw-Rúz. There is also the Ostara festival of Wicca religion, and is one of eight Sabbat festivals of new-style polytheists (neopagan).

In Japan, the spring day (phân の 日) is the official national holiday for people to go to graves and reunite their families.

Easter in Christian countries is celebrated on the first Sunday immediately after the full moon since the Spring equinox.

Earth Day is celebrated on the year of the Lunar New Year since the first day is March 21, 1970.

Feeling the day of spring equinox from nature, heaven and earth

Because our Earth's orbit is not vertical, it is 23 degrees above the zodiacal plane, so there will be more places to receive light from the Sun than in the other hemisphere, and at 2 days In the year, the Earth will head straight to the Sun, so day and night will be the same. But our Earth is constantly moving, so this equality will quickly be broken.

It is easy to see the sunny, cool wind, and the hot heat of summer approaching for the northern hemisphere. Also, if you live in the northernmost hemisphere, you will see the Sun rising from the eastern horizon over the next few weeks. The day will gradually get longer, the weather will be warmer, and the street will not need to be worn. You will see the Sun's path in the sky for one day gradually shift north.

Spring Fecal matter is good and reproduces.

Spring Fecal plants are both fresh and fertile, marked by spring thunder and spring-drenched rains. The air temperature rises and stabilizes, dispelling the cold. The old people have the saying 'The spring circuit wakes up, an engraved gold price', this is the best time to plant and prepare the crop.

In Xuan Phan section, the most remarkable spiritual activities and rituals are Thanh Minh's grave. On the spring day, descendants prepare offerings to visit and clean the ancestral graves to show filial piety and timely repair of damaged and degraded parts.

In this period, the yin and yang are balanced, the weather is harmonious, everything is good, the days and nights are as short and short as each other, so it is called Xuan Phap, ie, equally divided spring. The ancients took the landmark from Lap Xuan to Lap Ha in the spring and Xuan Phan was in the middle of that time, when the spring air was prosperous.

Spring equinox is not only good for farming, plowing, but also particularly beneficial for marriage, pregnancy and childbirth, promising good and peaceful things. Therefore, watching horoscopes often makes recommendations to work hard in Xuan Phan.

Spring day in Vietnam

Spring day in Vietnam is nothing special. However, many parts of the world choose this day as a festive day. The Easter day of Christianity is the first Sunday right after the full moon since the Spring equinox. Spring Day (春分 の 日) in Japan is a national holiday for people to go to graves and reunite their families, after the spring equinox period will arrive at Qing Ming on April 4.

On the day of Spring, the Sun goes north, the Fall day, the Sun goes south.(illustration).

The fecal day takes place twice a year, one in the spring is called the Lunar New Year in March, and the other in the fall is called the Fall day in September. On the day of autumn, the Sun goes south. The position of the Sun at the time of the equinox is used to determine the zero of both the ascension and the declination.

But in reality, these things are not entirely accurate, due to a phenomenon called the progression of the fecal points. Over hundreds of years, the rotation of the Earth's axis in space changes because it acts as a gyroscope. This means that the position of the decomposition points moves across the sky at a rate of 50 seconds per year.

Spring by meteorology

When it was the northern hemisphere's spring, it was autumn in the southern hemisphere and vice versa. In spring (or vernal) Equinox, day and night are about twelve hours long, with day length increasing and night length decreasing as the season goes on.

The subtropical and tropical regions are better described in other seasons, such as dry or wet, monsoon or tornadoes. Cultures may have local names for the seasons that are less equivalent to those derived from Europe.

Meteorologists often identify four seasons in many climates: spring, summer, autumn and winter. They are delineated by the values ​​of their average temperature on a monthly basis, with each season lasting three months.

The three warmest months are summer, the coldest three months are winter and alternating gaps are spring and autumn. Spring, when defined in this way, can start on different days in different areas.

Another name for the March Full Moon is Sap Round Moon, because this is the time of year when maple tree sugar begins to flow.

Therefore, in the US and the UK, the spring months are March, April and May, while in New Zealand and Australia, spring usually begins on September 1 and ends on November 30.

Swedish meteorologists define the beginning of spring as the first occasion where the average daytime temperature exceeds 0 degrees Celsius for seven consecutive days, so the day changes with latitude and altitude.

There is a change in concept with astronomers

In some Northern Hemisphere cultures, for example in Germany, astronomical equality changes from March 19 to March 21 to mark the first day of spring and the summer solstice on June 21 taken. is the first day of summer.

In Persian culture, the first day of spring is the first day of the first month (called Farvardin) starting on March 20 or 21. In other traditions, this day is chosen as mid-spring.

In the traditional Chinese calendar, the "spring" seasons (春) include the mid-spring days (May 3-5), taking the spring equinox (February 20-22) is its midpoint, then ending at Lixia (May 5-7).

Similarly, according to Celtic traditions, relying only on daylight and the power of the midday sun, spring begins in early February and continues until early May.

The beginning of spring is not always determined by a fixed calendar day.

Spring is related to biological indicators, such as flowering of a variety of plant species, animal activities, and the distinctive smell of soil that has reached the temperature for micro-flora to grow.

These indicators, along with the beginning of spring, vary according to the local climate and the specific weather of a particular year. Most ecologists divide the year into six seasons without a fixed date.

In addition to the spring, ecological calculations determine a separation before the prevernal season (early or pre-spring) between the hibernal season (winter) and vernal (spring).

This is the time when only the hardest flowers like crocus are blooming, sometimes while there are still a few snowflakes on the ground.

In early spring, the Earth axis is increasing its inclination to the Sun and the length of the daylight increases rapidly for the related hemisphere. The hemisphere began to warm up significantly, making the development of a new "sprouting" tree, naming this season.
