1988 Gregorian calendar

1988-6-9, April 25th of the lunar calendar, the main branch: the second day of Wu-nian Chen, correct.

The dividing point of the trunk and branch is in the solar term, not in the number of lunar months, and the dividing point of the moon column is in the solar term of mango.

You think: the moon column of Chen Wunian in April is Ding Si, which is wrong. The moon column cannot be determined by the number of months in the lunar calendar.

The period of the fourth month in the year of Wuchen is (1988-5-5, long summer solar term, March 20th of the lunar calendar) to (1988-6-4, before the solar term, April 20th of the lunar calendar).

The time of May Day of Chen Wunian is from (the solar term of mango on April 21st of the lunar calendar 1988-6-5) to (before the solar term of light summer on May 23rd of the lunar calendar 1988-7-7).
