I would like to ask: under the premise that there are two April in leap year, are the 24 solar terms still accurate? Wait ... Wait until New Year's Eve, isn't it a month later?

Leap year: it is a tool to convert the errors between Gregorian calendar and lunar calendar, specifically, it is seven leap years in nineteen years.

Because the lunar calendar is the period when the moon revolves around the earth,

There are only 28 to 30 days in a month and 354 to 355 days in a year.

It does not conform to the law that the earth revolves around the sun for about 365 days.

So it took 19 years and 7 leap months to make it up.

The twenty-four solar terms were determined by the ancients according to natural phenomena, which basically coincided with the corresponding time of the Gregorian calendar.

Therefore, the 24 solar terms are more accurate, or the Gregorian calendar is more accurate and more suitable for our reality.

(Note: New Year's Eve is not a solar term)
