Origin of the lunar calendar
The lunar calendar, also known as the perpetual calendar, is a type of calendar based on the cycles of the moon. It is a unique calendar. In fact, the lunar calendar is the Islamic calendar, in which each year contains exactly 12 lunar months. The characteristic of a purely lunar calendar, as in the case of the Islamic calendar, is that it is a continuous cycle of the full moon and is not tied to seasons. Therefore, the Islamic lunar year is about 11 or 12 days shorter than each solar year, and only returns to align with the solar year after every 33 or 34 Islamic years. The Islamic calendar is used primarily for religious purposes. In Saudi Arabia, the calendar is also used for commercial purposes.
Most other types of calendars, whether called "lunar calendars" or perpetual calendars, are in fact lunisolar calendars. This means that in these calendars, the months are maintained according to the cycle of the Moon, but sometimes leap months are added according to certain rules to adjust the lunar cycles to match the solar year. Currently, in Vietnamese, when people talk about the lunar calendar, they think of a calendar based on the principles of the Chinese calendar, but modified according to UTC+7 instead of UTC+8. It is a lunisolar calendar in the truest sense, not a purely lunar calendar. Because the calculation of the lunar calendar differs from that of China, the Vietnamese Lunar New Year sometimes does not completely coincide with the Spring Festival of China and other countries influenced by Chinese culture and the Sinocentric cultural sphere.
Because the purely lunar calendar has only 12 lunar months (corresponding months) in each year, this cycle (354.367 days) is sometimes also called a lunar year.
Lunar and Solar Calendar
The lunisolar calendar is a type of calendar used by many cultures, in which the dates indicate both the lunar phase (or lunar cycle) and the duration of the solar year (solar calendar). If the solar year is defined as the tropical year, the lunisolar calendar will provide indication of the seasons; if it is calculated according to the astronomical year, the calendar will predict the constellations near which a full moon (the "see-see") is likely to occur. There is usually an additional requirement that a year contains only a natural number of months, in most years 12 months, but every two (or three) years there is a year with 13 months.
