Japanese calendar types have included a range of official and unofficial systems.

The sexagenary cycle, also known as the ganzhi or stems-and-branches is a cycle of sixty terms, each corresponding to one year, thus a total of sixty years for one cycle, historically used for recording time in China and the rest of the East Asian cultural sphere and Southeast Asia. It appears as a means of recording days in the first Chinese written texts, the oracle bones of the late second millennium BC Shang dynasty. Its use to record years began around the middle of the 3rd century BC. The cycle and its variations have been an important part of the traditional calendrical systems in Chinese-influenced Asian states and territories, particularly those of Japan, Korea, and Vietnam, with the old Chinese system still in use in Taiwan, and in Mainland China. In India, the Ahom people also used the sexagenary cycle known as Lak-Ni.

Yu and other sage-kings of ancient China were lauded for their virtues and morals by Confucius and other Chinese teachers. He is one of the few Chinese monarchs who is posthumously honored with the epithet "the Great".

Yubu, translated as Pace(s) of Yu or Step(s) of Yu, is the basic mystic dance step of religious Daoism. This ancient walking or dancing technique typically involves dragging one foot after another, and is explained in reference to the legendary Yu the Great, who became lame on one side of his body from exerting himself while establishing order in the world after the Great Flood. Daoist religions, especially during the Six Dynasties period (220–589), incorporated Yubu into rituals, such as the Bugang 步罡 "pace the Big Dipper", in which a Taoist priest would symbolically walk the nine stars of the Beidou 北斗 "Big Dipper" in order to acquire that constellation's supernatural energy.
Bugang is a Daoist ritual dance or walk, based upon the Yubu "Steps of Yu" tradition, in which a Taoist priest paces through a supernatural pattern, such as stars in the Big Dipper or numbers in the Loshu magic square. Texts from the Shangqing School revelations contain the earliest descriptions of bugang, frequently with the practitioner pacing among constellations, especially the Big Dipper's stars. When religious Daoism began during the Six Dynasties period, the expression bugang tadou 步罡踏斗 "pacing the guideline and treading on the Dipper" became popular.

The sanshi 三尸 "Three Corpses" or sanchong 三蟲 "Three Worms" are a Daoist physiological belief that demonic creatures live inside the human body, and they seek to hasten the death of their host. These three supernatural parasites allegedly enter the person at birth, and reside in the three dantian "energy centers", respectively located within the head, chest, and abdomen. After their human host dies, they are freed from the body and become malevolent ghosts.
Shijie, which has numerous translations such as liberation from the corpse and release by means of a corpse, is an esoteric Daoist technique for an adept to transform into a xian, typically using some bureaucratic ruse to evade the netherworld administrative system of life and death registration. The many varieties of shijie range from deceitful cases, such as a person feigning death by substituting the corpse of their recently deceased grandfather as their own, to supernatural cases, such as using a waidan alchemical sword to temporarily create a corpse-simulacrum, which enables one to escape and assume a new identity.

There are examples in Greek, Latin, Coptic, Middle English and Old Nubian. Pagan, Jewish and Christian examples are known. The lunary was "by far the most popular and widely circulated prognostic genre" during the Middle Ages.
