Who knows how to divide the big moon and the small moon? What is the big moon and the small moon

To distinguish between a big and a small month, you need to keep the following rules in mind:

There are 12 months in a year, with the big months being January, March, May, July, August, October, and December, and the small months being April, June, September, and November. Among them, February is a special month, with 28 days in February in a common year and 29 days in February in a leap year.

When distinguishing between large and small moons, you can use the method of making a fist with one hand: make a fist with one hand downward, and the concave and convex position on the back of the hand can be used to distinguish between large and small moons. Counting backwards from the index finger, the convex one is the big month, the concave one is the small month, and the last one is July (because July needs to be counted from the beginning).

It should be noted that July is a big month, and August is also a big month, because in July you have already counted the uneven positions on the back of your hand, and you need to start counting from the beginning.

January is the big month and February is the small month.

Common year. It's 28 days, leap year.

It is 29 days) to distinguish between big and small months with our hands, clenched fists, counting from the index finger, 1 month old (raised at the joint, recorded as large), 2 months small (there is a depression between the index finger and the middle finger, recorded as small), 3 months old, 4 months small, 5 months large, June small, 7 months old (at this time the little finger has been counted, counting from the index finger), so August is large, September is small, October is large, November is small, and December is large

The year is divided into twelve months, and the number of days in each month is irregular, with the big month being thirty-one days and the small month.

Thirty days, twenty-eight days in a common year and twenty-nine days in a leap year.

The month of the solar calendar has nothing to do with the movement of the moon, but the year is divided into twelve parts, and the meaning of the month is lost. Except for February, which is divided into ordinary and leap years, the number of days in each month of each year is certain: before July, there are 31 days in a single month and 30 days in a double month; After August, there are 31 days in a double month and 30 days in a single month.

The origin of the big month and the small moon of the solar calendar: In 46 BC, the Roman commander Julius Caesar.

Specify the calendar. Since he was born in July, in order to show his greatness, it was decided to change the month of July to the month of Julian, which together with all the single months was 31 days, and the double month of Blind Land was 30 days. So there is one more day a year, and February is ancient Rome.

In order to reduce the number of executions, the month of February was reduced by one day to 29 days.

Caesar's heir, Augustus.

Born in August, he followed Caesar's practice by adding one day to the month of Augustus, making it the month of Augustus, and changing the months of October and December to 31 days, and the months of September and November to 30 days. There was one more day in the whole year, and he subtracted one day from February, so that February became 28 days, and in leap years it was only 29 days.

In this way, there is a single month before July as a big month, and a double month after July as a big month, with 28 days in February. It is not a natural law that the number of days varies from month to month of the year.

It's a man-made rule.

The big month and the small month are divided into the lunar calendar and the solar calendar:

1. The lunar month is 30 days, the small month is 29, the big month and the small month make up for each other, which month is bigger and which month is different in a year, sometimes two, three, four big months or two or three small months in a row. Since the synodic month is slightly larger than 29 and a half days, there are about 53 major months and 47 minor months for every 100 calendar months in the lunar calendar.

2. There are certain rules for the size of the month in the solar calendar, and the single month before July is the big month, and the double month is the small month; After August, the double month is the big month, and the single month is the small month, thus.

January, March, May, July, August, October, and December are the big months, and April, June, September, and November are the small months. The common year of the Gregorian calendar is divided into 12 months, the 31st day of the big month, the 30th day of the small month, and the 28th day of the second month, and the average of the calendar months is roughly equal to the average length of the synodic month.

January is large, February is small, March is large, April is small, May is large, June is small, July is large, August is large, September is small, October is large, November is small, and December is large. The easiest way is to clench your left hand into a fist, count from the left, the bone joints are bulging is January is the big month, the intermediate recessed is February is the small month, and then count back from the right in July, exactly August is also the big month, and so on.

Hold the fist of your left hand, look at the protruding bone joints on your hands, and count from the right, the big moon on the bone joints is the big moon, and the small moon in the middle of the bone joints, for example: January is big, February is small, and March is big. Notice that when you count to the age of July, you start from the beginning again in August (i.e. count again from the right), so August is big!

Then just keep counting as usual!

Big Moon Little Moon: A must-see for elementary school students! There is a way to quickly memorize the big and small moons.

Before July, a single month is a big month, and a double month is a small month. After August, the double month is the big month, and the single month is the small month. Thereupon.

January, March, May, July, August, October, and December are the big months, and April, June, September, and November are the small months. February is neither a big month nor a small month. February has 28 days in a common year and 29 days in a leap year. <

The big moon and the small moon are how to distinguish between the big moon and the small moon

1. The pat of the solar calendar is divided into big months and small months, the big month is 31 days in a month, and the small month is within 30 days in a month These months are big months The month is a small month, and only February has only 28 days (ordinary year) or 29 days (leap year) in February.

2. The size of the month began in the time of Caesar in the Roman Empire. Caesar sent people to revise the calendar and establish the Julian calendar, which stipulates that all months of special religious significance are 31 days, and those that are not important are 30 days. Therefore, there are 31 days in January, which is named after the god of war, March, which is named after the god of war, and July, which is named in honor of Julius Caesar.

Because February is the month of execution, it is an inauspicious time, so it is only 29 days. Julius Caesar's successor, Augustus, named August after himself. In order to equate himself with Caesar, he asked for the month of August to be added to the 31 days.

In order to have 31 days in August, he borrowed one day from February and reduced February to 28 days. In order to avoid the three big months being combined, the months of September and November were each set to be 30 days, and October and December were added to 31 days.

We all know that there are 360 days in a year, we subdivide these days into 12 months, among the 12 months, they are divided into 7 big months, 4 small months and a flat month, so how to divide the big month and the small month? What's the difference between a big moon and a small moon?

How to divide the big moon and the small moon.

The so-called big moon and small moon refer to the concept of synodic months.

The average length of a synodic month is 29 days, 12 hours, 44 minutes and 3 seconds (days), which is not an integer, and the number of days in a month must be expressed as an integer, so people use the method of setting the minor month as 29 days and the major month as 30 days, so that the average length of the calendar month is close to the synodic month.

In order to ensure that the first day of the lunar month must be the day of the new year, the major and minor months should be determined according to the number of days between the two occurrences. A major moon is a 30-day interval between the two moons, and a minor month is a minor month when the interval between the two moons is 29 days.

The difference between the big moon and the small moon.

January, March, May, July, August, October, December, these seven months all have 31 days, and we call the month with 31 days a big month.

April, June, September, November, these four months all have 30 days, and we call the month with 30 days a small month.

February is neither a big month nor a small month.

How to memorize the size of the month.

To know how many days there are in a month, you can count the twelve months in turn on the fist of the left hand. Wherever you count to the bulge, each month is 31 days, and where you count to the concave, every month is 30 days except February.

Formula: one, three, five, seven, eight, ten, wax, thirty-one days is never bad.

Why are there so few days in February?

In 46 BC, the Roman Emperor Julius. Caesar modified the calendar to stipulate 12 months of the year, 365 days for a year, and a leap year every four years, because of Julius. Caesar was born in July, so he designated July as the Great Month, with 31 days, to show his honor.

In this way, there are 31 days in a single month and 30 days in a double month.

But if you do that, in the middle of the year, there are 31 days in 6 months, 30 days in 6 months, and 366 days in a year, which is one more day than 365 days, and you have to try to subtract one day from the whole year. In which month do you subtract one day? At that time, according to Roman custom, February was the month of execution, and the execution of criminals was carried out in February, which was an unlucky month, and everyone hoped that February would pass quickly, so one day was removed from February, and it became 29 days.

Later his nephew Augustine became emperor of Rome, in order to show and Julius. Caesar, with equal dignity, changed the month of August to 31 days of his birth, and reversed the four months of the month. One day was added to August, and subtracted from the inauspicious month of February, so that February would have only 28 days, and only 29 days in leap years.
