Based on the lunar calendar we use today, what are these achievements related to today's 24 solar terms?

A calendar in China, which is a kind of lunar calendar, is generally called lunar calendar. Normal year 12 months, 30 days in the big month, 29 days in the small month, and 354 or 355 days in the whole year (which month is big and which month is small in a year, which varies from year to year). Because the number of days in each year is about eleven days worse than that in the solar year, there are seven leap months in nineteen years, and there are 383 or 384 days in a year with leap months. According to the position of the sun, a solar year is divided into 24 solar terms to facilitate agricultural planting and other activities. The chronology is matched with heavenly stems and earthly branches, with a period of 60 years. According to legend, this calendar originated in the Xia Dynasty, so it is also called the Xia calendar. Also known as the old calendar.

Today's 24 solar terms are related to the position of the sun.

According to the position of the sun, set 24 points a year. Each point is called a solar term. Usually also refers to the day when each point is located.

Solar terms refer to the 24 solar terms and climate, which is a supplementary calendar made by China to guide farming in ancient times. Because the lunar calendar in China is a kind of "yin and yang calendar", which is based on the movement of the sun and the moon, it can't fully reflect the solar cycle. But China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is entirely based on the sun. Therefore, the "twenty-four solar terms" that reflect the solar cycle alone are added to the calendar as the standard for determining leap months. China's orthodox twenty-four solar terms are based on Henan.
