Why does the China lunar calendar leap in April and the Korean lunar calendar leap in March this year?

The lunar calendar is related to solar terms, and the winter solstice is 1 1 month, and so on. There should be a Grain Rain in March, a full moon in April, a summer solstice in May, and a leap month without a neutral atmosphere.

China belongs to the East Eighth District, and the energy is abundant on May 20th, 201February, so it is April 30th of the lunar calendar, and the next lunar month (Gregorian calendar 2065438+02.05.21-06.18) is only awn.

South Korea belongs to the East Ninth District, and Xiaoman is in this district on May 2 1 Day 0: 15. So, the leap April of the lunar calendar, which was originally neutral in China, according to the Korean saying, includes the small and full neutrality, so this month can't be regarded as a leap month, and there is also the month before it (Gregorian calendar 2012.04) .40100.000000001005

To sum up, because of the time difference between the two countries, this year's Xiaoman China is on May 20th, while Korean is on May 2nd1day, so it is a whole month to count as a lunar leap month.
