When did calendars become popular?

Calendar from ancient times to the present, there are three versions: 1. Calendar or something. This refers to books with years, months, days, weeks, solar terms, anniversaries, etc. One book a year, one page a day, and withdrawal day by day. Some are hung on the wall, others are on the table. 3. Historians' daily records of national events are the basis for historians to compile national history.

Calendars are often decorated with images, and monthly cards are one of the decorative paintings of calendars.

Calendars and desk calendars are all developed from calendars, but this is only a history of nearly a hundred years. As for when the calendar appeared, no one can say for sure, but according to historical records, it was already in use in the palace of Yongzhen Garden in Tang Shunzong about 1 100 years ago. At that time, the calendar, also known as the imperial calendar, not only recorded dates, but also was an important material for compiling national history. At that time, the calendar divided the year into 12 volumes, determined the number of pages of each volume according to the number of days in each month, and wrote the month and date on each page, and then gave it to the eunuch who served the emperor for temporary storage until the eunuch recorded the emperor's words and deeds on the blank page every day and gave it to the emperor at the end of each month. After approval, they were sent to historians for archiving.

Historians then combined the calendar with events in the imperial court and China, refined and polished it, and recorded it, which became a national history. Later, because the calendar brought a lot of convenience to life, it gradually entered the families of many senior officials in North Korea. After some changes, it was compiled into its own calendar. Later, with the development of popular calendars and family calendars, people printed calendars with lunar calendars, solar terms and auspicious days, leaving a large blank for keeping records.

The real calendar appeared in Tang Shunzong Yongzhen Garden about 1 100 years ago, and the royal calendar has been used in the palace. The first day is a page, recording the state, court events and the words and deeds of the emperor. The imperial calendar is divided into twelve volumes, each volume has the same number of pages as the number of days per month, and each page indicates the number of days and dates. Nowadays, popular calendars, whether paper publications, mobile phone applications or electronic desk calendars, usually include solar calendars, lunar calendars and dry calendars.

The origin of the lunar calendar

The calendar will display the date of the day in big letters and predict solar terms, luck and other conditions of the day.

The month, day, branch, festival and other contents are written on it in advance, and the bottom is left blank for notes, similar to the "desk calendar". At that time, the eunuch who served the emperor wrote down the words and deeds of the emperor in the blank space of the calendar. At the end of the month, after being verified by the emperor, it was sent to the historian for the record. This was called calendars at that time, and these calendars were later used as the basis for historians to write national history.

Later, court ministers followed suit and compiled calendars for their own use. As for the monthly calendar, it has only been nearly a hundred years since it developed into various forms such as wall calendar and desk calendar. With the development of the times, although the types of calendars are increasing and the patterns are constantly being renovated, the pattern of ancient calendars is still maintained.

The origin of dry calendar

Its formation has a process, starting from the date. As early as the Shang Dynasty, there were twelve calendar years in China, and twelve overtime days were adopted in the Spring and Autumn Period and the Warring States Period. From the end of the Western Han Dynasty to the present, we have been using dry branches to record the years. After the Tang Dynasty, the names of the calendars of the Five Dynasties began to be marked with branches. In the Northern Song Dynasty, the ten branches and twelve branches were combined with time. At this point, the calendars of trunk and branch are marked with trunk and branch, and the trunk and branch are becoming more and more complete.

Beginning of spring is the first year in the official calendar, and the year of return is the year of old age. 12 month is divided by 24 solar terms (i.e. silver moon, Uzuki, Chen Yue, etc. ), and 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 known by China officials and the people, and it has been applied to astronomy, geomantic omen, numerology, choice and traditional Chinese medicine, and recorded in official almanac (i.e. 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.

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. In fact, just because two calendars are recorded in the almanac at the same time, it cannot be considered that the lunar calendar is a dry calendar. If it takes hundreds of years, doesn't the solar calendar include the lunar calendar? Just because the society is dominated by the Gregorian calendar.

The origin of Gregorian calendar

The calendar we are using now is one year 12 months, with 365 days in a normal year and 366 days in a leap year. This calendar is a kind of solar calendar, which can be traced back to the calendar reform of Julius Caesar in ancient Rome in 46 BC. Caesar adopted the advice of Sosigenes of Alexandria, an ancient Roman astronomer, and set a year as 365 days, a leap year as 366 days, a year divided into 12 months, and a leap day every four years, so that the average year is 365.25 days. Caesar's name is Julia Ceasar, so the calendar made by Caesar is called julian calendar.
