What is the lunar calendar?

01 The Gregorian calendar, also known as the solar calendar, is a solar calendar based on the cycle of the Earth's motion around the sun. The lunar calendar, the traditional Chinese calendar, is a yin and yang calendar, based on the moon phase cycle of the lunar month as the basis for the calendar month, and based on the solar return annual cycle to calculate the time of the year. Generally on a calendar, the Gregorian time is on top and the Lunar time is on the bottom.

The difference between the Gregorian calendar and the lunar calendar:

1. The Gregorian calendar, also known as the solar calendar, is a solar calendar. It is a calendar based on the cycle of motion of the Earth's revolution around the Sun. The return year of the cycle of the four seasons as the basic cycle, independent of the moon's change of the moon, in which the number of days and months of each year is specified by the person. Today, the world's common calendar is a solar calendar.

2, the lunar calendar, the traditional Chinese calendar, is the yin and yang calendar. The lunar phase change cycle of the lunar month as the basis of the calendar month, and according to the solar return annual cycle to calculate the time of the year.

3, the location of the different: generally in the calendar, the Gregorian calendar time on the top, the Lunar Calendar time in the bottom; and the Gregorian calendar date is Roman numerals, while the Lunar Calendar is capitalized.

The calendar can be divided into solar, lunar, yin and yang calendar three:

solar calendar (solar calendar): to the Sun's annual visual movement cycle (ie, the return year, about the same as the day) for a year, a year is divided into 12 months, which has nothing to do with the movement of the moon. According to the date of the solar calendar, it is possible to know the change of the seasons and the rational guidance of agriculture. The Gregorian calendar (scientific name Gregorian calendar) is a kind of solar calendar.

The lunar calendar: China's lunar calendar belongs to this category, it takes the cycle of the moon phase changes that the lunar month for the length of the month, the reference solar return year for the length of the year, through the setting of intercalary month in order to make the average calendar year and the return of the year to adapt. According to the lunar calendar date, you can know the tides, but also roughly grasp the change of seasons.

Lunar calendar (Taiyin calendar): China's lunar calendar does not belong to this category, but in life people are accustomed to call the lunar calendar. The moon's cycle (i.e., the lunar cycle, equal to the day) for a month, 12 months for a year. It does not take into account the sun's annual visual movement law at all, so the date of the lunar calendar can not show the four seasons of warmth and cold. The practical value of this calendar is too small, now in addition to Islam, has been abandoned.
