Is the summer solstice time based on the lunar calendar or the Gregorian calendar? Are the solar calendar and the Gregorian calendar the same?
Most of China's traditional culture is based on the lunar calendar. So, let's take a look at whether the time of the summer solstice is based on the lunar calendar or the Gregorian calendar? The most prosperous herb in May is calamus, so the fifth month of the lunar calendar is also called the calamus month. Shuimoxiansheng.com has prepared relevant articles about the fifth month of the lunar calendar in 2020, welcome to check them out.Is the summer solstice time based on the lunar calendar or the Gregorian calendar?It is calculated according to the Gregorian calendar.The summer solstice is one of the 24 solar terms in my country. The 24 solar terms can reflect the changes of seasons, guide agricultural activities, and affect the food, clothing, housing and transportation of thousands of households. The 24 solar terms are divided according to the position of the sun on the ecliptic (the orbit of the earth around the sun). Considering the sun starting from the vernal equinox (0 degrees of ecliptic longitude, when the sun shines vertically on the equator), every 15 degrees forward is a solar term; a circle of movement and return to the vernal equinox is a tropical year, which totals 360 degrees, so it is divided into 24 solar terms. The dates of the solar terms are relatively fixed in the Gregorian calendar. For example, the beginning of spring always falls between February 3rd and 5th in the Gregorian calendar. But in the lunar calendar, the dates of the solar terms are difficult to determine. Taking the Beginning of Spring as an example, it can be as early as the 15th day of the 12th lunar month of the previous year and as late as the 15th day of the first lunar month. Are the solar calendar and the Gregorian calendar the same?No, the Gregorian calendar time and the Gregorian calendar time are different.Lunar calendar: also known as the lunar calendar. He determined the length of a month by the waxing and waning of the moon. The month has nothing to do with the Earth's orbit around the sun (the four seasons of cold and hot weather). The length of a year is just an integer multiple of a month. The moon's waxing and waning cycle is 29.5306 days (12:44:03 hours on the 29th), which is called a synodic month. Because the calendar stipulates that a month must be a whole number of days, some months in a year have 29 days and some months have 30 days. This adjusts the average length of the calendar month to be consistent with the moon's waxing and waning cycle. Lunar calendar: also known as the old calendar, is a type of lunar calendar and was mistakenly called the lunar calendar in the past. Since it has been used in our country for many years, it is customarily called the lunar calendar. Its characteristics are: it pays attention to the changes in the waxing and waning of the moon, and also takes into account the four seasons of cold and hot weather in a year. In order to coordinate the movements of the sun and the moon in the calendar, the "19-year and 7-leap month method" is adopted, that is, one month (leap month) is added to 7 years in 19 years, and the other years still have 12 months. A year with 13 months is called a leap year, with 383 to 385 days. A year with 12 months is called a normal year, with 353 to 355 days. This leap-year calendar is quite accurate. This calendar divides the solar year into 24 solar terms according to the position of the sun on the ecliptic to facilitate farming. The disadvantage is that the number of days in ordinary years and leap years differs greatly. People born at different times will have different destinies due to their different genders.
