The origin of the lunar calendar

When it comes to lunar calendar, you have to say lunar calendar and solar calendar. In the lunar calendar, the moon revolves around the earth for one month, that is, the new moon, as the basis for determining the calendar month. To put it simply, ancient people calculated according to the profit and loss of the moon. The time for the moon to orbit the earth is about 29 and a half days, which is about 354 to 355 days a year.

The solar calendar, also known as the new calendar, is just the opposite of the lunar calendar, which means that the earth orbits the sun for one year, that is, 365 days, so every four years, 366 days this year is called leap year, which completely exceeds the 10 to1day in the lunar calendar algorithm.
