Calculation method of pig year

When the AD number is divided by 12, the year with the remainder of 3 is the year of the pig.

The formula is: the number of years in AD ÷ 12= a quotient, and the remainder is 3.

For example: 2007÷ 12= quotient 167, and the remainder is 3. So 2007 is the year of the pig. For example, 1935, 1947, 1959,197, 1983, 1995, 2007,20/. Once every twelve years. Note that the above is only a rough correspondence, because the Gregorian calendar and the elephant trunk calendar in China, which are widely used in the world, are two different calendars.

The Year of the Pig is counted from beginning of spring in the twenty-four solar terms, because the zodiac year is attached to the calendar year of the trunk and branch, and the calendar year of the trunk and branch is the calendar year method of the trunk and branch. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar). There is no doubt that the lunar calendar only uses branches to mark the year, which ranges from the first day of the first month to New Year's Eve. Lunar calendar and trunk calendar are two different calendars, which are different in the starting point of a year, the division rules of months and the number of days in each year. Due to the use of the Gregorian calendar after the Republic of China, many people, including a few so-called experts, lack calendar knowledge, so the two are often confused.

The trunk calendar is a calendar marked with 60 different heavenly stems and earthly branches, which is a unique solar calendar in China. It takes beginning of spring as the beginning of the year, and divides the year into twelve months with twenty-four solar terms. Every month contains two solar terms, and there is no leap month. The dry calendar is related to the periodic movement of the earth around the sun, which can reflect the climate change throughout the year. Since ancient times, the Ganzhi calendar has been widely recognized by the government and the people, and has been applied to astronomy, geomantic omen, numerology, choice and traditional Chinese medicine, and recorded in the official almanac of past dynasties (that is, the Yellow Calendar). Take Qing Dynasty official history book Qing Shi Lu as an example. The official editing years in the book are divided into beginning of spring: for example, Zhonghua Book Company photocopied Book 17 of Qing Shi Lu, Book 9 of Qianlong Shi Lu, with 573 pages, beginning of spring, 20071February 22 (Geng Xu), and Record is recorded as: "Geng Xu. This is the beginning of last spring. " See also the ninety-fifth chapter of A Dream of Red Mansions in Qing Dynasty: "beginning of spring on December 18th of Jiayin year is December 19th of silver moon year". It is clearly pointed out here that the transition point of the dry calendar is in the year.
