Origin of the Perpetual Calendar

The term "perpetual calendar" in ancient China did not refer to a calendar that could be used for ten thousand years, but rather generally referred to a calendar book capable of calculating the correspondence between Lunar and Gregorian dates, solar terms, moon phases, and other astronomical phenomena over a very long period (usually hundreds or even thousands of years). Its origin can be traced back to the long-term observation and calculation of the movement patterns of the sun, moon, and stars by ancient astronomers. Ancient people compiled calendars to guide agricultural production, sacrificial activities, and daily life, so calendars held a very high status in ancient society. Modern perpetual calendar tools, based on this, combine computer technology to achieve more convenient and accurate date query and conversion functions.

Perpetual Calendar and Traditional Culture

The perpetual calendar plays an extremely important role in traditional Chinese culture. It is not only an important reference for agricultural activities, helping farmers grasp the best time for sowing and harvesting; it is also the carrier of traditional festivals, such as the Spring Festival, Qingming, Dragon Boat Festival, Mid-Autumn Festival, which are closely related to Lunar dates. In addition, the information contained in the perpetual calendar, such as daily auspicious and inauspicious days, zodiac signs, constellations, and the Five Elements, is deeply integrated into people's daily customs. For major decisions such as weddings, funerals, business openings, and housewarmings, people often refer to the almanac to choose an "auspicious day and time", reflecting the Chinese pursuit of favorable timing, geographical advantage, and human harmony, and their respect for traditional wisdom.
