Lunar calendar

A lunar calendar is a calendar that is based on cycles of the lunar phases. This can be contrasted with the Gregorian calendar, which is a solar calendar based on the revolution of the Earth around the sun. Because there are slightly more than twelve lunations (synodic months) in a solar year, the period of 12 lunar months (354.37 days) is sometimes referred to as a lunar year.

A common purely lunar calendar is the Islamic (or Hijri Qamari) calendar. A feature of the Islamic calendar is that a year is always 12 months, so the months are not linked with the seasons and drift each solar year by 11 to 12 days. It comes back to the position it had in relation to the solar year approximately every 33 Islamic years. It is used mainly for religious purposes, but in Saudi Arabia it is the official calendar. Other lunar calendars often include extra months added occasionally to synchronize it with the solar calendar.

The oldest known lunar calendar was found in Scotland at Warren Field and dates back to around 8,000 BC.Alexander Marshack, in a controversial reading, believed that marks on a bone baton (c. 25,000 BCE) represented a lunar calendar. Similarly, Michael Rappenglueck believes that marks on a 17,000-year-old cave painting in Lascaux represent a lunar calendar.

Chinese calendar

The Chinese calendar is a lunisolar calendar which reckons years, months and days according to astronomical phenomena. It is used for traditional activities in China and overseas Chinese communities. It determines the dates of traditional Chinese holidays, and guides Chinese people in selecting the luckiest days for weddings, funerals, moving, or beginning a business.

In the Chinese calendar, the days begin and end at midnight. The months begin on the day with the dark (new) moon. The years begin with the dark moon near the midpoint between winter solstice and spring equinox. The solar terms are the important components of the Chinese calendar. There are one to three solar terms within a month.

The present Chinese calendar is the product of centuries of evolution. Many astronomical and seasonal factors were added by ancient scientists, and people can reckon the date of natural phenomena such as the moon phase and tide upon the Chinese calendar. The Chinese calendar has over 100 variants, whose characteristics reflect the calendar's evolutionary path. As with Chinese characters, different variants are used in different parts of the Chinese cultural sphere. In Korea, Vietnam, and the Ryukyu Islands, the Chinese calendar was adopted completely. In Japan, the Chinese calendar was used before the Edo period, and the later Japanese calendar used the algorithm of the Chinese calendar.

Calendar

A calendar is a system of organizing days for social, religious, commercial or administrative purposes. This is done by giving names to periods of time, typically days, weeks, months, and years. A date is the designation of a single, specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills.

Periods in a calendar (such as years and months) are usually, though not necessarily, synchronized with the cycle of the sun or the moon. The most common type of pre-modern calendar was the lunisolar calendar, a lunar calendar that occasionally adds one intercalary month to remain synchronised with the solar year over the long term.

The calendar in most widespread use today is the Gregorian calendar, introduced in the 16th century as a modification of the Julian calendar, which was itself a modification of the ancient Roman calendar. The term calendar itself is taken from calendae, the term for the first day of the month in the Roman calendar, related to the verb calare "to call out", referring to the "calling" of the new moon when it was first seen. Latin calendarium meant "account book, register" (as accounts were settled and debts were collected on the calends of each month). The Latin term was adopted in Old French as calendier and from there in Middle English as calender by the 13th century (the spelling calendar is early modern).

Chinese people

Chinese people are the various individuals or groups of people associated with China (or Greater China), either by reason of ancestry or heredity, ethnicity, nationality, citizenship, place of residence, or other affiliations.

Ancestry or heredity

A number of ethnic groups within the region of China, as well as people elsewhere with ancestry in the region, may be referred to as Chinese people.

Han Chinese, the largest ethnic group in China, are often referred to as "Chinese" or "ethnic Chinese" in English. Han Chinese also form a majority or large minority in other countries, and may comprise as much as 19% of the global human population.

Other ethnic groups in China include the Zhuang, Hui, Manchu, and Uyghurs, among many others. The People's Republic of China (PRC) officially recognizes 56 distinct ethnic groups, some of whom live in special administrative regions of the country. Taiwan officially recognizes 14 tribes of Taiwanese aborigines, who together with unrecognized tribes comprise about 2% of the country's population. The list of ethnic groups in China includes the major ethnic groups of China (PRC) and Taiwan.
