Excuse me, what is the difference between the Tibetan calendar and the lunar calendar we usually use? Thank you.

Tibetan traditional calendar. Yin and Yang have always been 1300 years old. According to Tibetan literature, it was founded in Songzan Gambu, the king of Sambo Dynasty, and is still popular among the people. At first, Tibetans used phenological observation, with wheat ripening as the beginning of the year; Later, influenced by the ancient Han calendar and Indian calendar, an era began in Shen Jia (624) in the seventh year of Tang Wude, which was called the era of "fire, air and sea". By the middle of the 7th century, the chronology of the twelve-year cycle began. By the beginning of the 9th century, the 60-year periodic chronology was used. In the fifth year of Song Tiansheng, Ding Mao (1027), translated from India into Tibetan, is the Tibetan Year of the Rabbit. In Tibetan, this year is elegantly called "Rao Qiong", which means "life", so it is called "Zhou Shengsheng era". From the year of the rabbit with yin fire to the year of the tiger with yang fire, 60 years is called "Rao Qiong", that is, a cycle of 60 years. The Tibetan calendar is 365.270645 solar days longer and 29.5587 days longer, starting from the first day of the first month. The chronology method is based on the coordination of Yin and Yang, five elements and the zodiac, that is, wood, fire, earth, gold and water are ten, and rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs and pigs are arranged in twelve genera, and the order is the same as the sixty-year cycle of the coordination of the ten heavenly stems and twelve earthly branches in the Han Calendar. A year is divided into four seasons: spring, summer, autumn and winter, and there are four solar terms: vernal equinox, summer solstice, autumn equinox and winter solstice. Each quarter is divided into Bangladesh, China and Kyrgyzstan, representing three months; In 12 months, there are 30 days for large-scale construction and 29 days for small-scale construction. There are twenty-four leap months every sixty-five years, that is, one leap month is accumulated every thirty-two and a half months. Every month is divided into three days: morning, noon and evening. January 15th is called hope, and the 30th is called gloom. A week is divided into seven days: day, month, fire, water, wood, gold and earth, with day as Sunday; When the zodiac signs are recorded every day, the order is the same as the China calendar. In order to configure the solar day to correspond to the date series of lunar day, there are "white days" in the Tibetan calendar, that is, one day is important, and "black days" are short, commonly known as auspicious days and ominous days. Tibetan calendar accurately calculates five-star running direction, food limit value, food delivery time, food delay time, food intake direction, etc. It can also make medium and long-term weather forecast, which is welcomed by foreign residents in people in Xizang, Nepal, Sikkim and Bhutan. Academic qualifications belong to the cleverness and cleverness in the "five Ming" of Buddhism; The study of Tibetan calendar is listed as astrology in the "Little Five Ming" of Tibetan Buddhism. There are dozens of books handed down from generation to generation. In major monasteries, there are institutions that study Tibetan medical calendars. In the 15th "Raoqiong" Year of the Rabbit (19 16), Lhasa established "Menzikang", namely the Tibetan Medicine Tibetan Calendar Institute (now Tian Wen Astrology Institute of Xizang Autonomous Region Tibetan Hospital), which compiles and publishes the Tibetan Calendar Yearbook every year and distributes it among Tibetans at home and abroad.
