The perpetual calendar is wrong, how is the perpetual calendar time inaccurate

That's right. Generally, every 19 years, the solar calendar and the lunar calendar are on the same day.

This situation is mainly the result of the intercalation of the lunar calendar. Why is there an overlap in 19 years? The number of days in a lunar month is established according to the cycle of the moon's movement, in fact, the average number of days in a month is days, if multiplied by 12, there are only days in a year; And the earth revolves around the sun for one cycle (return year, solar year) is days, so the actual number of days in a lunar year is less than that of a solar year, almost 11 days, and 19 years is 209 days less.

209 days divided by 30 is, that is, in 19 years, the lunar year is almost 7 months less than the solar year. In order for the lunar calendar to be not too different from the solar calendar, it is necessary to make up these 7 months.

The Chinese lunar calendar is actually a typical lunisolar calendar——— which is formulated by taking into account the movement cycle of the moon around the earth and the movement cycle of the earth around the sun——— and is a calendar combining the lunar calendar and the solar calendar, in order to make up for these 7 months, people take the method of setting leap months in the lunar calendar——— 19 years and 7 leaps, that is, in the 19 years of the lunar calendar, 12 are ordinary years, and 12 months are every 1 ordinary year; Add 7 leap years (each the first year) for 13 months for every 1 leap year.

In this way, the number of days in the 19 solar years is about the same as the number of days in the 19 lunar years, so every 19 or 19 times the number of birthdays, there is a chance that the solar birthday and the lunar birthday will occur on the same day.

Whether it is a lunar month or a solar year, their exact number of days is not an integer but a decimal, there is a slight difference in the number of days in the 19 years of the lunar calendar and the solar calendar, after decades or even hundreds of years of accumulation, the decimal number has become a large number, so that this phenomenon occurs, but it is generally only one day.

For example: October 20, 1946, September 26 of the lunar calendar

October 20, 1965, September 26 of the lunar calendar

October 20, 1984, September 26 of the lunar calendar

October 20, 2003, September 25 of the lunar calendar

October 20, 2022, September 25 of the lunar calendar

October 20, 2041, September 26 of the lunar calendar
