What is the personal tailor almanac? Is the zodiac fortune pushed by WeChat official account accurate every day?

Popularize the astronomical calendar knowledge used by my yellow calendar.

0 1 What is a calendar?

Calendar is a method to calculate time according to the astronomical phenomena in order to meet the needs of people's daily life. At present, there are three kinds of calendars mainly used:

1, the calendar set according to the moon's orbit around the earth is called the lunar calendar;

2. The calendar based on the earth's orbit around the sun is called the solar calendar;

3. According to the fact that the moon revolves around the earth, the calendar in which the earth revolves around the sun is called the lunar calendar.

What calendar is used in my yellow calendar?

The calendars used in my solar calendar are solar calendar, lunar calendar, dry calendar and phenological calendar, among which the most important one belongs to my solar calendar, Fuxi 64 Gua Fiona Fang map calendar. According to the above calendar and personal numerology information, each person's unique solar calendar fortune is generated.

1, Gregorian calendar:

In my solar calendar, solar term divination and ecliptic divination are calculated by Gregorian calendar. In astronomy, the Gregorian calendar is more accurate every year than the lunar calendar. In modern astronomy, there are two sets of calculation standards in a year:

A. sidereal year

Observed in the universe, the actual time required for the earth to go around the sun is called "sidereal year", ***365 days, 6 hours and 9 minutes 10 second.

B. Tropical Year/Year of the Sun

Observed on the earth, the time interval between the two passes of the sun through vernal equinox is called "tropic year/solar year", ***365 days, 5 hours, 48 minutes and 46 seconds.

Astronomy is applied to the diachronic period, and we usually take the sidereal year as the standard.

The year when the earth moves around the sun is 365 days, 6 hours and 9 minutes 10 second, which is about 6 hours more than the 365 days in the Gregorian calendar. Therefore, every four years in February of the solar calendar, that is, leap month, 1 day will be added. Because in four years, the time for the earth to go around the sun is just nearly 24 hours longer than that of the Gregorian calendar, so the accuracy and scientificity of the Gregorian calendar year are beyond doubt, which is also my responsibility.

2. Lunar calendar

The time for the earth to go around the sun is about 10 days from the lunar calendar and about 6 hours from the Gregorian calendar. In order to correct the annual time error, the lunar calendar has set up a leap month, that is, a year plus one month.

Although the error of lunar calendar is larger than that of Gregorian calendar, the arrangement of lunar calendar is more telling. The solar calendar only needs to coordinate the two periods of the earth's rotation and the earth's revolution, while the lunar calendar needs to coordinate the period of the moon's revolution around the earth in addition to these two periods, so the lunar calendar is a kind of yin-yang calendar.

Therefore, although the lunar calendar is not as accurate as the Gregorian calendar in one year; But on the time scale of one month, the lunar calendar is more accurate than the solar calendar, which takes into account the phase change of the moon (the first month of the lunar calendar), that is, the time period during which the moon orbits the earth. It takes a month for the lunar leap month to adjust the error of the earth's revolution around the sun, and it is also because of the change of the moon phase, that is, the cycle of the moon's revolution around the earth is exactly one month.

According to the changes of the lunar calendar, my yellow calendar establishes the 5th, 14th and 23rd of the lunar calendar as the death day of the month (Mafia Day).

3. Phenological calendar

Phenological calendar is a special calendar compiled according to the date sequence of natural phenomena, which is a comprehensive reflection of the influence of climate and other environmental conditions. According to the previous phenological period, the date of the next phenological period can be predicted.

At present, the phenological time is based on the solar altitude angle formed by direct sunlight on the latitude of the earth to judge the 24 solar terms, and the time when the solar terms intersect is different every year.

4. Dry calendar

The dry branch calendar is a calendar marked by 60 different groups of dry branches and earthly branches, which mainly consists of four parts: dry branch calendar, dry branch calendar, dry branch calendar and dry branch calendar. It takes beginning of spring as the beginning of the year and festivals as the beginning of the month. 10 heavenly stems and 12 earthly branches are matched in turn to form 60 basic units, forming a 60-cycle epoch method, and 24 solar terms are 24 special festivals in heavenly stems and earthly branches calendar representing seasonal changes.

In addition, it takes 12 years for Jupiter to orbit the sun once, and it will meet Saturn three times in 60 years, so we call 60 years Jiazi, and each year corresponds to Ron Artest (that is, Jupiter).

How scientific is my almanac algorithm?

The Gregorian calendar is not an independent and closed calendar system like the solar calendar and the lunar calendar, but a compound calendar system integrating the lunar calendar, phenological calendar and dry calendar.

The strict definition of the ecliptic in astronomy is: the instantaneous average orbital plane of the center of mass of the earth-moon system rotates around the sun and intersects the celestial sphere. We can simply understand it as the orbital plane of the earth revolving around the sun.

The reason why the Yellow Calendar is more instructive than the separate calendars such as the lunar calendar and the solar calendar is precisely because it integrates the calculation of various calendars. The Gregorian calendar has always been promulgated by the ancient government, announcing the year number, festivals and solar terms of the coming year, reflecting the objective laws of natural time changes and meteorological changes, guiding the agricultural production of working people, and also serving as the basis for the signing date of government documents. In addition, according to the characteristics of natural laws and the number of Yijing techniques, daily taboos and good and bad luck are established to avoid bad luck.

My almanac is supported by the most accurate astronomical data algorithm. The biggest feature is the function of a personal tailor. According to one's own zodiac sign, Jupiter and divination of the core monuments of life, one can determine good and bad luck, taboos, suggestions on clothes, food and friends, and combine with one's own calendar.
