What day is May 20, 2022

May 20, 2022 is World Bee Day and World Stranger Day.

Initiated by the Slovenian Beekeeping Association in April 2015, the 44th International Beekeeping Congress & Expo held in Daejeon, South Korea, from 15 to 20 September 2015, decided to accept the proposal of the Slovenian Beekeepers Association to designate May 20 as World Bee Day. The Chinese Society of Beekeeping and China Bee Products represented China in the meeting, which was a strong promoter of the establishment of "World Bee Day".

May 20 is also known as the Day of the Living. Because this festival does not require gifts, it is also called rudeness, and it aims to save the social credibility of modern people and help people get rid of emptiness and loneliness.

May 20, 2022 is also Internet Valentine's Day:

Internet Valentine's Day is a love holiday in the information age, which is scheduled on May 20 and May 21 every year. The festival originated from the close connection between "I love you" and "I love you" in singer Fan Xiaoxuan's "Digital Love", as well as the close connection between "I love you" and "Internet lover" in the Internet song of ** person Wu Yulong.

Later, "521" was gradually given the meaning of "I do, I love you" by couples. "Internet Valentine's Day" is also known as "Marriage Day", "Confession Day", "Coquettish Day", and "Courtship Day".

Hello, dear. May is big in June, small in July, big in August. September is small, October is big. November small. 12 months old.

Hello, 7 days in May (including the 25th).

June 30 days.

July 3l day.

August 31 days.

September 30 days.

November 30 days.

December 31 days.

January 29, 2022.

So it's a total of 2l9 days.

= 248 days.

That's a total of 248 days as of today.

How many days is it from May 24, 2021 to April 12, 2022?

It was two hundred and forty-nine days.

From May 20, 2019 to May 20, 2022, it is exactly 3 years, 365 + 366 + 365 = 1096 (days).

1096 days in total (1097 days in total if both start and end dates are counted).

Among the calculation problems, there is a kind of problem that needs to be calculated by recursive equation called off-form calculation problem. Each row must be calculated with an equal sign first, followed by the result. Format 99+1-35*2 =100-70 =30 The operation rules must be from left to right, and the operation must be calculated according to the rule of "multiplication and division first, then addition and subtraction", and the numbers in parentheses, middle brackets, and curly brackets must be counted first.

Various algorithms can be used to make their calculations easier and more accurate. (Note: Formulas can contain letters.)

Off-Form Computation - What is Detached Computation Off-form computation, that is, recursive equation computation, is an operation that writes the calculation process in its entirety, that is, it is out of vertical computation. When calculating mixed operations, it is usually necessary to calculate one equation at a time (step-by-step calculation, the equal sign cannot be written on the original formula), and the process of each step must be written. In general, the equal sign should go forward and not align with the first line.

That is, to leave the original calculation. Off-Entry Calculations - The Order of the Four Operations: In the four operations, addition and subtraction are called first-level operations, and multiplication and division are called second-level operations. An equation that contains two or more operations is often referred to as a hybrid operation.

The mixed operations of addition, subtraction, multiplication, and division are also called four mixed operations. In the four mixed operations, the specified order of calculations is called the order of operations. The mathematically prescribed order of four operations is as follows:

1) Sibling operations in an equation, if only sibling operations are included, they should be performed in order from left to right. That is, mixed operations with only addition and subtraction, or only multiplication and division, in the order of operation from left to right. (2) First-level and second-level operations In an equation, if there are both first-level operations and second-level operations, then the second-level operations should be counted first, and then the first-level operations.

That is, "multiplication and division first, then addition and subtraction", referred to as "multiplication and division first, then addition and subtraction". 4) Parentheses If you want to change the order of operations mentioned above, you need to use parentheses. There are three commonly used parentheses:

Small parentheses, denoted as parentheses in ( ), denoted as [ ; Braces, denoted as When using parentheses, pull on both sides and add them in the middle. Use parentheses first, then braces, and finally curly braces. In an equation, if there are several parentheses, the ones in the parentheses should be counted first, then the ones in the brackets, and finally the ones in the curly braces.

When calculating, the formula inside the parentheses should be calculated in the order mentioned above, and then the resulting result should be calculated in the same order as the numbers outside the parentheses. (5) Simple algorithm change sign If there is a minus sign outside the parentheses, there is a plus sign or a minus sign inside the parentheses, and the number in the brackets is changed. The parentheses are outside the plus sign, and the parentheses are plus or minus, and the sign is unchanged.

No entertainment.

May 22, 2022 is the day of prohibition of entertainment, on May 22, 2021, the father of hybrid rice Yuan Longping and the father of Chinese liver surgery Wu Mengchao passed away, May 22, 2022 is the first anniversary of the death of Academician Yuan Longping and Academician Wu Mengchao, which is a day when entertainment activities are prohibited nationwide.

On the surface, entertainment is forbidden. to show respect and praise for the deceased.

Yuan Longping (September 7, 1930-May 22, 2021) is a male Han nationality, born in Beijing, a person without party affiliation, and a native of De'an Maoxi County, Zhengjiujiang City, Jiangxi Province. He is a well-known agricultural scientist at home and abroad, the pioneer and leader of China's hybrid rice industry, a close friend of the Communist Party of China, an outstanding representative of non-party personages, a winner of the "Medal of the Republic", a former vice chairman of the Hunan Provincial Committee of the Chinese People's Political Consultative Conference, a former director of the National Hybrid Rice Engineering Technology Research Center, an academician of the Chinese Academy of Engineering, and is known as the "father of hybrid rice".

May 22, 2021The lunar calendar is April 11, 2021. The lunar calendar is the traditional Chinese calendar.

It is based on the phases of the moon.

Each phase of the moon changes to one month, and divides a solar return year into 24 phases to form the 24 solar terms.

By referring to the return year of the solar cong jujube, the leap month is set to adapt its average calendar year to the return year.

The meaning of the lunar calendar

The lunar calendar has both lunar and solar elements, and unlike the solar year, which is fixed at 365 or 366 days, the lunar year sometimes differs by one month in terms of days compared to the solar year, in order to reconcile the return year with the synodic month.

In between, Iwate then gave rise to the lunisolar calendar, which is the lunar calendar.

The lunar calendar is in the lunar and summer calendars.

On the basis of the combination of the solar calendar elements of a kind of yin and yang infiltration to make a calendar, take the change cycle of the moon phase, that is, the synodic month as the length of the month, and add the dry calendar.

The composition of the 24 solar terms, with reference to the solar return year as the length of the year, is set by setting leap months to adapt the average calendar year to the return year.

On May 22, 2022, the lunar calendar is the 22nd day of April.

May 20, 2022 is National Student Nutrition Day and World Metrology Day.

1. National Student Nutrition Day:

Founded in 1989, the Chinese Student Nutrition Promotion Association formulated a ten-year student nutrition work plan from 1991 to 2000 under the chairmanship of nutritionist Yu Ruomu, and in combination with the World Health Organization's strategic goal of health care for all in 2000. The program is named "Seedling Protection System Project", and May 20 is designated as the Chinese Student Nutrition Day.

2. World Metrology Day:

On May 20, 1875, 17 countries signed the "Metric Convention" in Paris, France, which is an agreement between the adoption of the International System of Units and the guarantee of consistent measurements on a global scale.

For more than 100 years, the International Metric Convention Organization has been responsible for ensuring the unification of international metrology standards.

1. It has played a huge role in promoting international development and accelerating the development of science and technology. In 1999, the 21st International Conference on Weights and Measures designated May 20 as "World Metrology Day" every year.

The festive significance of World Metrology Day

World Metrology Day is to make people fully aware of metrology, the science of measurement and the backbone of all science. From people's daily life, industry, commerce, medical care, international stay, to the most cutting-edge scientific machine high-tech field, the computer is always in practice, the study is the technical basis of all scientific development, and its important role does not need to be praised.

Although everyone needs to measure and use measurement everywhere, the meaning and role of measurement are rarely recognized and understood by people who benefit from measurement. This is one of the reasons why international organizations have designated May 20 as World Metrology Day every year.

Through the celebration of the world's most important day, we will increase publicity efforts to make people fully understand measurement, consciously use measurement, and strongly support measurement, so that measurement can better serve the development of industry, science and technology, and the national economy.
