The solar calendar is 1 1.2. What is the lunar calendar?

Today is September 17 of the Year of the Rat. The lunar calendar takes the change cycle of the moon phase, that is, the length of the moon is one month, plus the "24 solar terms" of the elephant calendar, and takes the length of the tropical year of the sun as the year. By setting leap months, the average calendar year adapts to the tropic year.

The lunar calendar is a calendar based on the lunar calendar (summer calendar) and integrating the solar calendar. So strictly speaking, the lunar calendar in China should not be called the lunar calendar, but the lunar calendar.

The relationship between lunar calendar and lunar calendar

The lunar calendar is based on the lunar calendar (summer calendar), combined with the components of the solar calendar, absorbing the 24 solar terms of the solar calendar as a supplement, and adjusting it to the tropic year through the leap method. Because it absorbs the 24 solar terms in the calendar, it can reflect the changes of seasons and guide agriculture and other things. Therefore, the lunar calendar has both lunar and solar elements.

The lunar calendar is a combination of yin and yang, which refers to a calendar that takes into account the relationship between the sun, the moon and the earth. The lunar calendar does not consider the movement of the earth around the sun, so the changes of the four seasons have no fixed time in the lunar calendar and cannot reflect the seasons. Unlike the Gregorian calendar, which is fixed at 365 days or 366 days, the Gregorian calendar sometimes differs from the Gregorian calendar by one month.
