The Thai lunar calendar (Thai: ปฏิทินจันทรคติ , rtgs: "patithin chanthrakhati" ,  ] , literally, "Specific days according to lunar norms"), 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 regular intervals.
Pana Sankranti, also known as Maha bisuba Sankranti, is the traditional new year day festival of Buddhists and Hindus in Odisha, India.
 The festival date is set with the solar cycle of the lunisolar calendar, as the first day of the traditional solar month of Mesha.
 This is identical to the purnimanta system of lunar month "Baisakh" (on Indian national system, it is the 24th day of Chaitra).
 It therefore almost always falls on 14 April every year on the Gregorian calendar.
The Ancient Macedonian calendar is a lunisolar calendar that was in use in ancient Macedon in the 1st millennium BC.
 It consisted of 12 synodic lunar months (i.e. 354 days per year), which needed intercalary months to stay in step with the seasons.
 By the time the calendar was being used across the Hellenistic world, seven total "embolimoi" (intercalary months) were being added in each 19-year Metonic cycle.
 The names of the ancient Macedonian Calendar remained in use in Syria even into the Christian era.
 The Macedonian calendar was in essence the Babylonian calendar with the substitution of Macedonian names for the Babylonian ones.
 An example of 6th century AD inscriptions from Decapolis, Jordan, bearing the Solar Macedonian calendar, starts from the month Audynaeus.
 The solar type was merged later with the Julian calendar.
 In Roman Macedonia, both calendars were used.
 The Roman one is attested in inscriptions with the name "Kalandôn" gen.
 καλανδῶν calendae and the Macedonian "Hellenikei" dat.
 Ἑλληνικῇ Hellenic.
 Finally an inscription from Kassandreia of about ca. 306-298 BC bearing a month Ἀθηναιῶν "Athenaion" suggests that some cities may have used their own months even after the 4th century BC Macedonian expansion.
The Birthday of the Monkey God is a cultural and religious holiday celebrated in Singapore on the 15th or 16th day of the First Lunar Month.
 The dates on the Western Calendar vary from year to year.
 It marks the birthday of Sun Wukong, the protagonist in the classical novel "Journey to the West".
 The popular celebratory customs associated with the Birthday of the Monkey God have both secular and religious (Taoist) themes.

The traditional Chinese calendar is a lunisolar calendar which reckons years, months and days according to astronomical phenomena.
 s of 2017 , the Chinese calendar is defined by GB/T 33661-2017 "Calculation and promulgation of the Chinese calendar," which the Standardization Administration of the People's Republic of China issued on May 12, 2017.
The Monkey King Festival () is celebrated in China on the 16th day of the eighth Lunar month of the Chinese calendar, corresponding to September according to the Common era calendar, a day after the Mid Autumn Festival.
 The origin of the festival is traced to an epic novel titled "Journey to the West" (Xiyou Ji, 西游记) written by the Chinese novelist Wu Cheng'en (1500–1582) in the 16th century during the Ming Dynasty (1368–1644).
 The novel brings out the concept of immortality from Taoism and rebirth from Buddhism.
 The monkey Sun Wukong, a character in the novel, is the featured figure of the festival.
An ecclesiastical full moon is formally the 14th day of the ecclesiastical lunar month (an ecclesiastical moon) in an ecclesiastical lunar calendar.
 The ecclesiastical lunar calendar spans the year with lunar months of 30 and 29 days which are intended to approximate the observed phases of the moon.
 Since a true synodic month has a length that can vary from about 29.27 to 29.83 days, the moment of astronomical opposition tends to be roughly 14.75 days after the previous conjunction of the sun and moon.
 The ecclesiastical full moons of the Gregorian lunar calendar tend to agree with the dates of astronomical opposition, referred to a day beginning at midnight at 0 degrees longitude, to within a day or so.
 However, the astronomical opposition happens at a single moment for the entire Earth: The hour and day at which the opposition is measured as having taken place will vary with longitude.
 In the ecclesiastical calendar, the 14th day of the lunar month, reckoned in local time, is considered the day of the full moon at each longitude.
