Traditionally, Chinese astronomy is traced back to the time of the legendary emperor, Fu-his (2852.B.C.). The measurements and reverent calculations of the royal astronomers provided the basis for the imperial calendar and yearbook. The yearbook fixed the lengths of the months, determined the dates of the spring and autumn equinoxes – the times a year that night and day are of equal length – and of the summer and winter solstices – when night and day differ the most in length.
Wan-nien, supposedly, created the ‘perpetual calendar’ or the ‘Wan-nien-li’ during the Shang dynasty (1766-1123 B.C.). He measured the time by noting the length of the shadows throughout the year with a gnomon template and the length of each day with a clepsydra (water-clock). By these empirical observations and measurements of the longest and shortest days in the year, he established the two solstices and the two equinoxes. Moreover, he concluded that there were three hundred sixty-five and a fraction of days within a year’s time. Afterwards, the phases of the moon, from dark to full and to dark again, which have no fixed relationship with the solar year, had to be included in the computations so that the calendar months could be adjusted to fit the year.

However, the choice of month for beginning the year changed with time and place. In the late second century B.C., a calendar modification was established, which continues even till today, regarding the winter solstice to occur in 11th month. This reform also introduced the intercalation system in which dates of New Moons are compared with the 24 solar terms. However, calculations were based on the mean motions resulting from the cyclic relationships. Inequalities in the Moon's motions were incorporated as early as the seventh century A.D., but the Sun's mean longitude was used for calculating the solar terms until
From 100 CE to 600 CE the Chinese had many cultural and political life changes and continuities. A political change was in the end of the Classical Chinese period when the Han Dynasty fell. A cultural change during 100 CE to 600 CE was the paper invention that led to passing down cultural rituals. Not only were there changes but there was also continuities in the Chinese political and cultural life. An example of a cultural continuity is the increasing power of Buddhism. A political continuity is the ruler of the Chinese wanting the people to be protected with for instance The Great Wall of China.
A group called the Powers had their own thrones of doom and were the “most holy gods.” They held council which shows already that order and rule was important. The Powers chose to give names to different times of the day spanning morning, afternoon and night and so on. This structure allowed for a calendar-like count of the days and years so that people could keep track of time. If the sun was visible in one position it was a certain time and they’d know that next the sun would set and then the moon would begin to rise marking the end of a
This book focuses on different types of calendars from a number of different places all around the world. This specific chapter, even more specifically this section, focuses on the Mayan calendar. These calendars were written by honored members of their aristocracy and were held to be of great value. The Spanish invaders believed them to be instruments of the devil and burnt great quantities of them. E. G. Richards explains that only four Mayan books are survive in the libraries of Europe, and one of those—The Dresden codex—suffered severe damage in another fire, one which was inflicted on that city in the Second World War. Richards says that the earliest record of a calendar survives from about 500 BC in Monte Alban near Oaxaca. This calendar employs a 260-day cycle, which was commonly used by several societies and is still in use among the present-day inhabitants of the region. The Maya used the calendar partly to anticipate propitious days to embark on wars and other activities. It was also used to record on stone pillars, or stelae, important events in the lives of their kings and to relate these to more mythical events of the past. The Mayan calendar system involved two major methods of specifying a specific date—the calendar round and the long count. The calendar round was used to specify a date within a period of about 52 years, while the long count served to relate such dates within a longer period named a great cycle. The calendar round involved three interlocking cycles of 13, 20, and 365 days respectively. The 365-day cycle was called a haab and was similar to the Egyptian wandering year. Each haab was divided into 18 periods called uinals; each uinal had 20 days and a name. The 18 uinal were followed by five epagomen...
The Han dynasty: The Han dynasty was one of the longest of China’s major dynasties. In terms of power and prestige, the Han dynasty is the East rivaled it’s almost contemporary Roman Empire in the West, it lasted a span of four centuries and was considered a golden age in Chinese history, especially in arts, politics, and technology.
Throughout the day we are constantly checking the time, preparing for the upcoming months, and keeping track of the year. Clocks tell us the time we use as a measurement. It’s how we keep track of those important months and events, such as holidays and birthdays. Although there are many investigations and research being done on the nature of time, many unresolved issues remain.
The Maya elite developed a complicated calendar system. There are two main cycles in their calendar; one was made up of 260 days and the other 365. Each day is named from both the 260 and 365-day calendars. Because of this each full day name could only repeat every 18,980 days or once every 52 years.
The Mesoamerican calendar consists of two time counting pieces. The first part is the 260-day divinatory calendar, which was imperative in Mesoamerican cosmology as well as in their personal lives. This repea...
In a Long Count calendar date there are five numbers which are separated by four periods (for example, 13.0.0.0.0). 13.0.0.0.0 is thought to have been the Mayan’s theory as to the world’s creation date. The Mayans used hieroglyphs, such as those in the image,
The Chinese use the lunar calendar. “Although China has adopted the Gregorian calendar in common with most other countries in the world for official and business purposes, the traditional Chinese calendar continues to define the dates of festivals and used for horoscopes” (“Chinese calendar”). The lunar calendar is based on of the moon. It uses the moon phases to figure out each month.

Due to archeological evidence we know that the African people were the first people in the world to use counting to keep track of their things, or time. Around 35,000 BC, in South Africa the earliest known tally stick was made, and was left in Lebombo Cave. 29 notches were cut into the stick. We don't know exactly what they were counting. Some people think they were counting the days from one moon phase to the next, but it could have been something else. Just as well. Now, what we do see is that by 35,000 BC people in South Africa had the idea of keeping records by making marks. “The Lebombo bone is a baboon fibula with a set of 29 notches carved in it. Archeologists believe these marks are evidence of a primitive calendar, measuring either the lunar or the menstrual calendar. This artifact is incredibly important for unders...
One cultural group was especially important for their discoveries in astronomy, the Egyptians. They were especially important because they were one of the first groups of people to create an accurate calendar. This calendar was different than others because it was based off of the Sun and stars rather than the moon. The calendars purpose was to make correct estimates of when to plan...
The ancient method of using the earth’s rotation around the sun as a method of keeping time requires one to add leap seconds to the time determined by atomic clocks in order to keep it coordinated with celestial time. This is because the earth has been slowing down over the years due to friction between ocean tides and the shallow sea floors caused by the gravitational pull of the moon. This moon causes the earth’s spin to slow down as much as 1.4 milliseconds or longer. In addition to this, irregular rotations of the earth occur because the molten core and the solid mantle of earth rotate at different rates. These esoteric motions make timekeeping very unreliable and cause the Earth day to be longer than that measured by atomic clocks and the length of...
