The first half of the year and the second half of the year each refer to the months from month to mo

January to June is the first half of the year, and July to December is the second half of the year.

Compulsory Education Act.

Provisions: All children who have reached the age of 6 before September 1 of the current year must be enrolled in school and complete compulsory education, and there is no explicit prohibition on children under the age of 6.

In fact, many places in the country generally implement the rule that children who are 6 years old can only enter school, so those children who are born a few months later cannot go to school, but many parents generally hope that their children can catch the 6-year-old bus, so some schools refuse to accept or charge fees in the name of "law".

Whether a child is really fit to go to school depends not entirely on the level of intellectual development, but also on many other factors, especially the child's physical and mental development: whether the child has a certain ability to live independently, whether he has a certain interpersonal skills. Therefore, whether you can go to school depends on the reality, and you must not blindly seek early, and let children go to school too early, which is at a "disadvantage":

It makes children have low self-esteem at the initial stage, which is not conducive to the sustainable development of children.

January to June is the first half of the year, excluding the last month of the first half of the year, June, isn't it July? Naturally, it's July to December.

Hey, June is the first half of the year, and July to December is the second half of the year. Thank you.

No, it should be divided from the beginning of autumn. The beginning of autumn is preceded by the first half of the year, and the beginning of autumn is followed by the second half of the year.

July-December. The first half of the year and the second half of the year refer to the division of the 12 months of the year into two parts, with January to June being the first half of the year and July to December being the second half of the year. So the second half of the year is from July to December.

Year, month, day, is a unit of time, according to which people rotate according to the earth.

The phenomenon of alternating day and night formed the concept of "day"; According to the moon, it revolves around the earth.

The concept of the "moon" is generated, and the earth revolves around the sun according to the idea of synodism.

The phenomenon of the alternation of the seasons has formed the concept of "year". The movement of matter on which these three concepts are based is a celebration of independence.

According to precise measurements, the time it takes for the Earth to revolve around the Sun is about an mean solar day, which is called a return year. The interval between one new moon and the next one occurs in succession is a mean solar day, which is called a synodic month.

The calendar is to estimate the length of the year, month, and day and the relationship between them, and the law of establishing the chronological order is called the "calendar". The method of arranging the number of integer months in a year, the number of integer days in a month, and the method of choosing the starting point of the year are called calendars.

The complexity of the calendar problem lies in the fact that the two cycles of the return year and the synodic month are so fragmented, that their relationship to the "day" is not as simple as the relationship between the kilometer and the meter; Moreover, they cannot communicate with each other. Therefore, the calendar always takes care of one and the other, and cannot coordinate two cycles at the same time. For these two reasons, the calendar is generally divided into three categories; Lunar calendar, solar calendar.

and lunisolar calendars. Focusing on the coordination of the relationship between synodic and lunar calendars is called the solar calendar, referred to as the solar calendar; The lunisolar calendar that takes into account both the synodic month and the return year, the calendar month and the calendar year.

July-December. The first half of the year, the first half of the year, the second half of the year from July to December. So the second half of the year is from July to December.

July-December. The first half of the year and the second half of the year refer to the division of the 12 months of the year into two parts, with January to June being the first half of the year and July to December being the second half of the year. Therefore, the half year of the town is from July to December.

January-June is the first half of the year, and July-December is the second half of the year. In the first half of the year, every 6th, the 21st is a solar term, the second half of the year is every 8th, and the 23rd is a solar term, which is generally one or two days apart.

The 24 solar terms table is a supplementary calendar established in ancient China to guide agricultural affairs, and is the crystallization of the long-term experience and wisdom of the ancient Chinese working people. It was formed during the Spring and Autumn Period and the Warring States Period. Because the Chinese lunar calendar is a kind of "luni-solar calendar", that is, according to the sun, but also according to the operation of the moon formulated, so can not fully reflect the solar cycle, but China is a boring society, agriculture needs to strictly understand the solar situation, agriculture is completely based on the sun, so in the calendar and added a separate reflection of the solar cycle of the "twenty-four solar terms", as a standard for determining the leap month.

The 24 solar terms can reflect the changes of the seasons, guide agricultural activities, and affect the clothing, food, housing and transportation of thousands of households. The 24 solar terms are divided according to the position of the Sun on the ecliptic (i.e., the Earth's orbit around the Sun).

Strictly speaking, a year is: (the return year of the Gregorian calendar) days, half a year is a day, and generally speaking, the first half of the year is: 181 days. The second half of the year is: 184 days.

The year of the Gregorian calendar is 365 days, which is calculated according to the fact that the earth revolves around the sun as a year. It takes a little more than 365 days and 5 hours for the Earth to revolve around the Sun. The Gregorian calendar has 31 days of 31 days and 30 days.

February is generally 28 days. February 4 has a 29-day day.

As for the 29 days of February of the year, as long as the year of the A.D. year is divided by 4, February of the year with no remainder is 29 days. For example, in 2004, divided by 4 and there is no remainder, then February of this year must be 29 days divided by 4, and February in these three years must be 28 days.

First, the division of the lunar calendar.

Second, the lunar month is used to divide the four seasons. Every year in the lunar calendar, January and March are spring, April and June are summer, July and September are autumn, and October and December are winter. Spring and summer are the first half of the year, and autumn and winter are the second half of the year.
