context_page_description: The traditional Chinese calendar, is a lunisolar calendar which reckons years, months and days according to astronomical phenomena. In modern days, it is defined in China by GB/T 33661–2017, "Calculation and promulgation of the Chinese calendar", issued by the Standardisation Administration of China on 12 May 2017.
  Although modern-day China uses the Gregorian calendar, the traditional Chinese calendar governs holidays—such as the Chinese New Year and Lantern Festival—in both China and in overseas Chinese communities. It also gives the traditional Chinese nomenclature of dates within a year, which people use for selecting auspicious days for weddings, funerals, moving, or starting a business. The evening state-run news program Xinwen Lianbo in the P.R.C. continues to announce the month and date in both the Gregorian and the traditional lunisolar calendar.
  Like Chinese characters, variants of this calendar are used in different parts of the East Asian cultural sphere. Korea, Vietnam, and the Ryukyu Islands adopted the calendar, and it evolved into Korean, Vietnamese, and Ryukyuan calendars.
context_section_description: China has used the Western hour-minute-second system to divide the day since the Qing dynasty. Several era-dependent systems had been in use; systems using multiples of twelve and ten were popular, since they could be easily counted and aligned with the Heavenly Stems and Earthly Branches.
