The traditional Chinese calendar is a lunisolar calendar, combining the solar, lunar, and other cycles for various social and religious purposes. More recently, in China and Chinese communities the Gregorian calendar has been adopted and adapted in various ways, and is generally the basis for standard civic purposes, but incorporating traditional lunisolar holidays. However, there are many types and subtypes of the Chinese calendar, partly reflecting developments in astronomical observation and horology, with over a millennium plus history. The major modern form is the Gregorian calendar-based official version of the Mainland China, although diaspora versions are also notable in other parts of China and Chinese-influenced cultures; however, aspects of the traditional lunisolar calendar remain popular, including the association of the twelve animals of the Chinese Zodiac in relation to months and years.
In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the naked eye, except when it is silhouetted against the Sun during a solar eclipse.
Vesak, also known as Buddha Jayanti, Buddha Purnima, Buddha Day, is a holiday traditionally observed by Buddhists in South Asia and Southeast Asia, as well as Tibet and Mongolia. It is the most important Buddhist festival. The festival commemorates the birth, enlightenment (Nibbāna), and passing (Parinirvāna) of Gautama Buddha in Theravada, Tibetan Buddhism and Navayana.
A solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. The Gregorian calendar, widely accepted as a standard in the world, is an example of a solar calendar. The main other types of calendar are lunar calendar and lunisolar calendar, whose months correspond to cycles of Moon phases. The months of the Gregorian calendar do not correspond to cycles of the Moon phase.
Thai New Year or Songkran is the Thai New Year's national holiday. Songkran is on 13 April every year, but the holiday period extends from 14 to 15 April. In 2018 the Thai cabinet extended the festival nationwide to seven days, 9–16 April, to enable citizens to travel home for the holiday. In 2019, the holiday was observed 9–16 April as 13 April fell on a Saturday. The word "Songkran" comes from the Sanskrit word saṃkrānti, literally "astrological passage", meaning transformation or change. It coincides with the rising of Aries on the astrological chart and with the New Year of many calendars of Southeast and South Asia, in keeping with the Buddhist and Hindu Calendar. The New Year takes place at around the same time as the new year celebrations of many regions of South Asia like China, India, Laos, Cambodia, Myanmar, Nepal, and Sri Lanka.
The Thai lunar calendar, or Tai calendar, is a lunisolar Buddhist calendar. It is used for calculating lunar-regulated holy days. Based on the SuriyaYatra, with likely influence from the traditional Hindu Surya Siddhanta, it has its own unique structure that does not require the Surya Siddhanta to calculate. Lunisolar calendars combine lunar and solar calendars for a nominal year of 12 months. An extra day or an extra 30-day month is intercalated at irregular intervals.
The Thai solar calendar was adopted by King Chulalongkorn in 1888 CE as the Siamese version of the Gregorian calendar, replacing the Thai lunar calendar as the legal calendar in Thailand. Years are now counted in the Buddhist Era (B.E.): พุทธศักราช, พ.ศ.RTGS: Phutthasakkarat which is 543 years ahead of the Gregorian calendar.
The Hindu calendar, also called Panchanga, is one of various lunisolar calendars that are traditionally used in the Indian subcontinent and Southeast Asia, with further regional variations for social and Hindu religious purposes. They adopt a similar underlying concept for timekeeping based on sidereal year for solar cycle and adjustment of lunar cycles in every three years, but differ in their relative emphasis to moon cycle or the sun cycle and the names of months and when they consider the New Year to start. Of the various regional calendars, the most studied and known Hindu calendars are the Shalivahana Shaka found in the Deccan region of Southern India and the Vikram Samvat (Bikrami) found in Nepal and the North and Central regions of India – both of which emphasize the lunar cycle. Their new year starts in spring. In regions such as Tamil Nadu and Kerala, the solar cycle is emphasized and this is called the Tamil calendar and Malayalam calendar and these have origins in the second half of the 1st millennium CE. A Hindu calendar is sometimes referred to as Panchangam (पञ्चाङ्गम्), which is also known as Panjika in Eastern India.
The traditional Korean calendar or Dangun calendar is a lunisolar calendar. Dates are calculated from Korea's meridian, and observances and festivals are based in Korean culture.
A panchāngam is a Hindu calendar and almanac, which follows traditional units of Hindu timekeeping, and presents important dates and their calculations in a tabulated form. It is sometimes spelled Panchāngamu, Pancanga, Panchanga, Panchaanga, or Panchānga, and is often pronounced Panchāng. Panchangas are used in Jyotisha.
The Buddhist calendar is a set of lunisolar calendars primarily used in Tibet, Cambodia, Laos, Myanmar, India, Sri Lanka, Thailand and Vietnam as well as in Malaysia and Singapore and by Chinese populations for religious or official occasions. While the calendars share a common lineage, they also have minor but important variations such as intercalation schedules, month names and numbering, use of cycles, etc. In Thailand, the name Buddhist Era is a year numbering system shared by the traditional Thai lunar calendar and by the Thai solar calendar.
Losar also known as Tibetan New Year, is a festival in Tibetan Buddhism. The holiday is celebrated on various dates depending on location tradition. The holiday is a new year's festival, celebrated on the first day of the lunisolar Tibetan calendar, which corresponds to a date in February or March in the Gregorian calendar. In 2024, the new year commenced on 10 February and celebrations ran until the 12th of the same month. It also commenced the Year of the Male Wood Dragon.
The Tibetan calendar, or Tibetan lunar calendar, is a lunisolar calendar, that is, the Tibetan year is composed of either 12 or 13 lunar months, each beginning and ending with a new moon. A thirteenth month is added every two or three years, so that an average Tibetan year is equal to the solar year.
The Tamil calendar is a sidereal solar calendar used by the Tamil people of the Indian subcontinent. It is also used in Puducherry, and by the Tamil population in Sri Lanka, Malaysia, Singapore, and Mauritius.
Buddha's Birthday or "'Buddha Day"' is a primarily Buddhist festival that is celebrated in most of South, Southeast and East Asia, commemorating the birth of the prince Siddhartha Gautama, who became the Gautama Buddha and founded Buddhism. According to Buddhist tradition and archaeologists, Gautama Buddha, c. 563-483 BCE, was born at Lumbini in Nepal. Buddha's mother was Queen Maya Devi, who delivered the Buddha while undertaking a journey to her native home, and his father was King Śuddhodana. The Mayadevi Temple, its gardens, and an Ashoka Pillar dating from 249 BCE mark the Buddha's birth place at Lumbini.
An Uposatha day is a Buddhist day of observance, in existence since the Buddha's time, and still being kept today by Buddhist practitioners. The Buddha taught that the Uposatha day is for "the cleansing of the defiled mind," resulting in inner calm and joy. On this day, both lay and ordained members of the sangha intensify their practice, deepen their knowledge and express communal commitment through millennia-old acts of lay-monastic reciprocity. On these days, the lay followers make a conscious effort to keep the Five Precepts or the ten precepts. It is a day for practicing the Buddha's teachings and meditation.
The Burmese calendar is a lunisolar calendar in which the months are based on lunar months and years are based on sidereal years. The calendar is largely based on an older version of the Hindu calendar, though unlike the Indian systems, it employs a version of the Metonic cycle. The calendar therefore has to reconcile the sidereal years of the Hindu calendar with the Metonic cycle's near tropical years by adding intercalary months and days at irregular intervals.
Māgha Pūjā is a Buddhist festival celebrated on the full moon day of the third lunar month in Cambodia, Laos, Thailand, Sri Lanka and on the full moon day of Tabaung in Myanmar. It is the second most important Buddhist festival after Vesak; it celebrates a gathering that was held between the Buddha and 1,250 of his first disciples, which, according to tradition, preceded the custom of periodic recitation of discipline by monks. On the day, Buddhists celebrate the creation of an ideal and exemplary community, which is why it is sometimes called Saṅgha Day, the Saṅgha referring to the Buddhist community, and for some Buddhist schools this is specifically the monastic community. In Thailand, the Pāli term Māgha-pūraṇamī is also used for the celebration, meaning 'to honor on the full moon of the third lunar month'. Finally, some authors referred to the day as the Buddhist All Saints Day.
The Burmese zodiac is the traditional Burmese system of astronomy and astrology. While it is still an important component of the Burmese calendar, today, the zodiac is closely identified with Burmese astrology, called Baydin (ဗေဒင်). Largely derived from Hindu astronomy and Vedic astrology, the Burmese zodiac consists of not only the same 12 signs of the Western zodiac but also 27 lunar mansions of the month and eight weekday signs.
Auspicious wedding dates refer to auspicious, or lucky, times to get married, and is a common belief among many cultures.
