Is there a pattern to the appearance of thirty?

At present, the global Gregorian calendar, the calendar year is based on the "return year" of the earth revolving around the sun, and its length is 365 24 days, that is, 365 days, 5 hours, 48 minutes and 46 seconds, and 365 days are taken as a year for ease of use, so that there are 5 hours and 48 minutes and 46 seconds more per year, and every 4 years is 23 hours, 15 minutes and 4 seconds, so the calendar sets a leap year every 4 years, which increases to 366 days, that is, there is an extra February 29. At the same time, all 100 AD years must be divisible by 400 to be considered leap years, so that there are exactly 97 leap years in every 400 years.

In addition, in the traditional lunar calendar arrangement in China, both the sun and the moon should be considered, and the month in the lunar calendar is determined by the length of the period between a "new moon" (astronomically the same moment as the moon and the earth's ecliptic plane) to the next "new moon", which is actually the time for the moon to revolve around the earth, with an average of 29 days, 12 hours and 44 minutes. Since the relative motion between the Sun, the Earth, and the Moon is not static, this cycle can be long or short, with 30 days for the Great Month and 29 Days for the Small Month. In order to ensure that the first day of each lunar month is a new day, the arrangement of the large and small months is not fixed, and needs to be determined through observation and calculation.

The first day of the first lunar month coincided with the small moon, so the Chinese New Year's Eve had to be "omitted".

Not only December, but also no month in the lunar calendar has 31, as for whether there is 30, it depends on whether this month is a big month or a small month. In fact, it is the time when the moon reaches the position of the new moon in the first half of the night or the second half of the night, and the day in the first half of the night (including the day) is counted until the next month, so the last month is 29 days, and the second half of the night is counted as the last month, which is 30 days.

At present, the global Gregorian calendar, the calendar year is based on the "return year" of the earth revolving around the sun, and its length is 365 24 days, that is, 365 days, 5 hours, 48 minutes and 46 seconds, and 365 days are taken as a year for ease of use, so that there are 5 hours and 48 minutes and 46 seconds more per year, and every 4 years is 23 hours, 15 minutes and 4 seconds, so the calendar sets a leap year every 4 years, which increases to 366 days, that is, there is an extra February 29. At the same time, all 100 AD years must be divisible by 400 to be considered leap years, so that there are exactly 97 leap years in every 400 years.

Careful people will open the calendar and find that after the 29th of the lunar month this year, it will directly reach the first day of the first month of the Year of the Dog, and there is no Chinese New Year's Eve. Why does this calendar phenomenon occur? This is due to changes in the relative motion between the three celestial bodies, the Moon, the Earth, and the Sun.

According to Ma Weihong of the Purple Mountain Observatory in Nanjing, Chinese Academy of Sciences, the Spring Festival is the New Year in the traditional Chinese lunar calendar, and its arrangement takes into account both the sun and the moon. The Chinese lunar calendar calculates the number of days in a month based on the "synodic month cycle", and the day of "Shuo" is the first day of the new year, which is the time when people cannot see the moon at all; The day of "hope" is the fifteenth day, which is the time of the full moon. Since the relative motion between the Moon, the Earth, and the Sun is not static, the "synodic month cycle" is long and short, and there is a division of 30 days for the big month and 29 days for the small month in the lunar year.

At the same time, in order to ensure that the first day of the lunar month must be a new month, the arrangement of the large and small months is not fixed, which needs to be determined through observation and scientific calculation. This year, the "Shuo" (first day of the first month) of the lunar month to the "first day of the new year" of the first month coincides with the small moon, so the Chinese New Year's Eve is omitted. It is also understood that the next Spring Festival without the Chinese New Year's Eve will appear in 2006.

Looking up at the ceiling imaging, it is using retinal residual image imaging technology.

About this technique, it is often left in the retina, imaged in the right brain, then subconsciously memorized, and finally projected onto the wall. When you look at the wall, you feel that the picture appears on the wall, and in fact the picture is already in your right head.

The picture that suddenly moved is a GIF moving image.,**The problem.,It's not interesting.,Don't explain it.。

Pure hand-to-hand, the landlord gives points, right?

You think it's an ordinary floor plan, but it's actually an animation class in GIF format.

The first 29 seconds of frame rate is set to static**, and the 30th frame number is inserted into a scary image**, which makes the effect you see.

If you look at a three-dimensional image, many people can't see the three-dimensional effect, but I just can't see the three-dimensional effect no matter how I look at it.

Three-dimensional painting is a painting made using the three-dimensional visual phenomenon of the human eye. Ordinary paintings and photographic works, including computer-generated three-dimensional animations, only use the human eye's perception of light and shadow, light and shade, virtual and real to obtain three-dimensional feelings, but do not use the stereoscopic vision of both eyes, and one eye and two eyes are the same. A three-dimensional painting that makes full use of binocular stereoscopic vision will allow you to see a wonderful world.

For details, please refer to:

It is a holiday on the first day of the new year, and it is a national holiday.

4 = 1 cube + 3

11 = 2 cube + 3

30 = 3 cube + 3

67 = 4 cubes + 3

So it's 128,5 cube + 3

Thank you, I hope it can help you, take it.

Recently, I read a book "Execution is in place", and I have a lot of insight that everything in the work is important to be in place. If the implementation is not in place, it is equivalent to no implementation; If the implementation is not in place, it is better not to implement it.

The key to implementation is often in the last 10%, and the last "ten miles" is completed, and the implementation will be successful, otherwise it will not be successful, and it will even bring bad consequences. Among them, there is a wonderful "30-day lotus law", which I will share with all friends!

Only a small portion of the lotus flowers bloom on the first day, and on the second day, they bloom twice as fast as the previous day. By the 30th day, the entire pond was in full bloom. Many people believe that by the 15th day, the lotus flowers will be halfway open.

But that's not the case! By the 29th day, only half of the lotus flowers are full, and the other half will not bloom until the last day. The last day was the fastest, equal to the sum of the previous 29 days.

Through the "Lotus Law", we see that the more everything goes to the end, the more critical and important it is. Maybe it's only one day away from leading the way, and we're missing out on success.

The moth breaks out of the cocoon and the bird comes out of the shell, both of which require important accumulation in the early stage, as well as the accelerated cocoon breaking out of the cocoon on the last day. Why don't we do the same in our dealings? As long as everything is done in place, how can it not be done?

There is nothing bad to do, only things that are not done well! Potato row ridges.
