1875 How many days are there?
The method of calculating leap year is
1, a leap year divisible by 400 in the middle of the century; (For example, 2000 is a leap year, 1900 is not).
2. A leap year is a year in which ordinary years are divisible by 4 and cannot be divisible by 100. For example, 2004 is a leap year, but 2005 is not.
According to the above method, 1875 is an ordinary year, which cannot be divisible by 4, so it is a normal year.
computation rule
1. The calculation of the occurrence time of all new moons and solar terms is based on the east longitude 120 degrees, that is, the standard time of the East Eighth District. However, when calculating the lunar calendar time before 1929, Beijing local time, that is, east longitude 1 16 degrees 25, shall prevail.
The day when the new moon appears is the first day of a month. If a solar term appears on this day, whether it appears before the new moon or not, it is counted as the new moon.
The annual winter solstice is always in 1 1 month this year. The period from the second day of the winter solstice to the next winter solstice is called one year old. If there are thirteen new moons in a year, then this year is a leap year, plus leap months.
The first month without gas in leap year is leap month. Because there is only twelve breaths in a year, there may be no breath for at least one month or two months in a leap year. But in this case, only the first month without breath is a leap month. When the month before leap month is a month, it is called leap month.
