The comparison table for converting the lunar calendar into the Gregorian calendar is Gregorian calendar1Sunday, April 29th, 945.

How to calculate the new lunar calendar? The new calendar you mentioned is Gregorian calendar, also known as solar calendar. It is calculated according to the earth's time around the sun for one year, that is, 365 days and 5 hours, nearly 6 hours, with an average of only 365 days a year. This extra five hours is nearly six hours, and an average of one day is added to February every four years, so sometimes February in the solar calendar has 29 days.

And the lunar calendar you said is the lunar calendar, also called the summer calendar. It takes a month, 29 and a half days, for the moon to be full and short at a time. A year is about 355 days, 30 days in the big month and 29 days in the small month. Because the difference between the number of days in the Lunar Year and the Earth Year (Gregorian calendar) is about 1 1 day, there should be a leap month every three years and seven leap months every 19, so that the average number of days in each year is close to the Earth Year (Gregorian calendar) to adjust the four seasons. The specific leap month depends on the elasticity of solar terms. For example, this year is leap May.

It is precisely because the Gregorian calendar and the lunar calendar have different calculation methods, different days and different starting times of the first day of each year, that the months and dates of the Gregorian calendar and the lunar calendar are out of sync, with a difference of about one month.

Because the Chinese calendar has always been used in the history of our country, it is also a national habit to determine people's birthdays in most parts of our country according to the lunar calendar when they were born.

However, due to the accurate and convenient timing of the Gregorian calendar, most countries in the world adopted the Gregorian calendar, and China officially adopted the Gregorian calendar as early as 19 12 after the Revolution of 1911. Therefore, in formal occasions, the date of birth is based on the Gregorian calendar, such as identity cards, file records, resumes, etc.

You can check the perpetual calendar, and it will be easy to understand after you know the above situation. I'll tell you a very simple way to look at the perpetual calendar. Generally, the date of the solar calendar is marked with * * * numbers, and the date of the lunar calendar is marked with China numbers below the * * * numbers.

As you said, 199 1 was born on April 7th:

1, if this is the date of the Gregorian calendar, then the corresponding * * * number on the calendar is April 7th below February 23rd in China, which is your birthday in the lunar calendar.

2. If this is the date of the lunar calendar, then the corresponding China number on April 7th will be your birthday on May 20th of the Gregorian calendar.

How to convert the new calendar into the lunar calendar First of all, the lunar calendar takes the month as the basic unit, and a month starts from the day when the new moon appears until the day before the next new moon appears.

Because the period of the moon's revolution is between 29 and 30 days, a month in the lunar calendar is also 29 or 30 days away from the appearance of the new moon.

The big moon is 30 days and the small moon is 29 days.

Unlike the solar calendar, large and small months are not fixed in different years.

For example, the day before the Spring Festival is usually called New Year's Eve, but in many years, such as the 2000 lunar calendar1February, there are only 29 days.

12 months is about shorter than the solar year 1 1 day, that is, the time for the earth to revolve around the sun.

In order to keep the lunar year and the solar year relatively stable, a leap month needs to be added every two or three years.

About every nineteen years, seven leap months will be added.

The 24 solar terms are determined by the position of the earth in its orbit around the sun.

Starting from the winter solstice every year, every 15 degree is a solar term.

Therefore, the 24 solar terms have roughly fixed dates in each month of the solar calendar.

In ancient times, the twenty-four solar terms guided farming, which is why the lunar calendar is also called the lunar calendar.

Among them, the twelve solar terms in the second half of the solar calendar are also called Zhongqi.

The occurrence time of geogas is directly related to the determination of leap month.

The calculation of the lunar calendar has the following four rules:

1. Exactly.

However, when calculating the time before the lunar calendar 1929, the local time in Beijing, that is, east longitude 1 16 degrees 25, shall prevail.

The day when the new moon appears is the first day of a month.

If a solar term appears on this day, whether it appears later than the new moon or not, it will be regarded as falling into the new moon.

The annual winter solstice is always in 1 1 month this year.

The period from the second day of the winter solstice to the next winter solstice is called one year old.

If there are thirteen new moons in a year, then this year is a leap year, and a leap month should be added.

The first month without gas in leap year is leap month.

Because there are only twelve breaths in a year, there may be no breath for at least one month or two months in a leap year.

But in this case, only the first month without gas is a leap month.

When the month before a leap month is a month, it is called a leap month.

According to the above information, we know that the lunar calendar is designated according to astronomical observation (maybe you can find the explanation in astronomy books).

In order to simplify the conversion calculation, many programmers have designed a routine based on the time period lookup table method.

How to convert lunar calendar into Gregorian calendar

Derivation of conversion formula of 1.

Gregorian calendar is 365.242 199074075 days per year (simplified as 365.2422 days), while Hijri calendar is 354.367074375 days per year (simplified as 354.36707 days), so Hijri calendar is only equivalent to 354.36707/365.2422 = 0.9723.2002020206 The New Year's Day of the first year of Muharram was set on July 16, 622 AD. Due to the calculation error of the calendar at that time, July 16 was changed to July 19 according to the modern Gregorian calendar, and the time from New Year's Day to July 19 of that year has reached 200 days. Stage 200/365.2422 = Because it didn't reach 0.970224 calendar year until the second year of Hijrayan, the formula for converting from Hijrayan to Gregorian is:

(Muharram 1 year1) × 0.924+622.76.200000000001

= Gregorian calendar date ............................................. (1)

Or hijri year × 0.970224+62 1.5774.

Among them, 62 1.5774 comes from 622.5476-0.9274.

If a historical fact is not found on New Year's Day, the total number of days that this fact has passed this year can be converted into Gregorian years and added to the total number of Gregorian years.

However, the total number of days in the above-mentioned Gregorian calendar year is actually the measured number in the tropic year, because the number of days in the current Gregorian calendar year is actually 365.2425, which can only be basically consistent with the number of days in the tropic year, and there will be a difference of one day after more than 4,000 years.

In fact, the Gregorian calendar in the ten years of Wanli in the Ming Dynasty, September 18, 990, 16, and before June 4, 1582 (including the 4th) is called julian calendar, while julian calendar has 365.25 days every year, which is far more different from the Gregorian calendar, that is, the modern Gregorian calendar, about/. Therefore, we can't still use (1) and (2) two formulas for the conversion between the official calendar and the official calendar in julian calendar period, but we need to slightly modify the above two formulas according to the actual number of days in julian calendar. The results are as follows:

（IJL）×0.9702+622.5393

= Gregorian calendar year, month, year, month, year, month, year, month, year and year (3)

Calendar year × 0.9702+62 1.569 1.

= Gregorian year, month, year, month, year, month, year, month, year, month, year, month, month, month, year, month, year and year (4)

Among them, 0.9702 is the result of 354.36707/365.25, 0.5393 is the result of the total days from New Year's Day to July 16 divided by 365.25, and 622.5393-0.9702 = 621.5549909.

Now, the following table lists the calendar year, month and day calculated by two formulas every 100 year from the 52nd Muharram month:

Convert the national calendar into Gregorian calendar

From the calculation results of the table, we can see that different calendars cannot use the same formula, otherwise the error will be great. 10 years ago, it was found that the vernal equinox date in julian calendar was quite different from the measured results, and it was 10 days in the ten years of Wanli. Therefore, Gregory XIII decided to revise julian calendar. There are two points in the reform. First, the day after Gregorian calendar 1582 10.04 should be changed from 10.05 to 10.00. Secondly, julian calendar has a leap year every four years and a hundred leap years in 400 years. The Gregorian calendar still maintains the Confucian tradition of a leap year every four years, but only 97 leap years are arranged every 400 years, and there is no leap year every 100 years in 400 years, and a leap year will be added after 400 years [6]. The chronological facts of julian calendar and Gregorian calendar are as follows:

Confucian calendar (365×300+366×00)÷400 years = 365.25 days/year.

Gregorian calendar (365×303+366×97)÷400 years = 365.2425 days/year and "Ming history? The * * * palace calendar (solar calendar) contained in this calendar is one hundred and twenty-eighth leap ... ";

How to convert the lunar calendar into a new calendar? The lunar calendar is the ancient time calculation method in China, and the solar calendar is the international common time calculation method. 1993 lunar September 13 is October 27th of Gregorian calendar 1993 10.

About the difference between Gregorian calendar and lunar calendar: Gregorian calendar is solar calendar and lunar calendar is lunar calendar. Because the Gregorian calendar is international, it is used all over the world. Lunar calendar is a traditional chronology in China, with China characteristics. People in China are using it.

1970 There is no comparison table between Gregorian calendar and lunar calendar, only perpetual calendar. If you want to know the conversion between Gregorian calendar and solar calendar, it is more convenient to look up the perpetual calendar.
