My humble opinion: the solar calendar, also known as the new calendar, is now an international calendar. 365 days a year, divided into 12 months. For example, Wednesday 202 1 Gregorian calendar 65438+ 10/3. Lunar calendar, also known as lunar calendar, summer calendar and lunar calendar, is a traditional calendar in China. The trunk calendar is called trunk by heavenly stems and earthly branches for short. Tiangan 65,438+00, followed by Jiayangmu, Yiyinmu, Bingyanghuo, Dingyinhuo, Wuyangtu, Jiyintu, Gengyinjin, Xinyinjin, Nonyangshui and Guiyinshui. 12 earthly branches, in turn, are Rat, Ugly Cow, Silver Tiger, Maotu, Chen Long, Sishe, Wuma, Weiyang, Shenhou, Ji You, Dog and Haizhu. According to the original meaning of ancient times, the original meaning of heavenly stems is trunk, and the original meaning of earthly branches is branch. Originally used to record the sun, it is called the chronology of branches and branches or the chronology of Jiazi. Later, it was used to record time, month and year, which was called the time, month and year method. For example, 202 1 is the year of the ox. The Almanac, also known as the General's Book, is a book that won a great victory. It details the usage of proper and taboo every day and so on. For example, 202 1 Gregorian calendar 1 June 16, April 4th day, closed day and Saturday. Ji Xing: God forgives the day, God is gracious, God is there, God wishes, Liuhe, Four Phases, Official Day, Moon Day, and the afterlife. Appropriate: sacrifice, security, burial, opening, traveling, cooking, closing accounts, seeking heirs, buying and selling, carving, moving, etc. Avoid: ask for advice and open a position.
