Question about current reality
Conclusion: The current Guest Currency is 3,000 years later. We will differ from the actual time.
The rules of the current reality schedule should be more clear, the specific calculation rules are as follows
Pingren years: 365 days
Leap year: 366 days
Specific in the forefront, the rules of the leap year calculation are shown below
Enter a year
Except 400?
Except for 100?
Except 4?
average year
leap year
Yes
Yes
Yes
no
no
no
The rules are specified as follows:
It is a leap year (2000,2004,2008,199,400,2008,1996)
Some actual examples:
It is definitely a leap year (such as 2000, 2400, 2800)
Can be unable to except 100 but not 400 is the year (2100, 2200, 2300)
It is definitely the whole year (such as 1999, 2001, 2002, 2003, 2005)
According to the above description, there are 97 leap years in 400, the total number of days is
365 * 400 97 = 146097
From the surface, I can know the average number of days per day.
146097/400 = 365.2425
According to the current international astronomy observation, the actual earth around the sun around the sun is 365.2422 days.
Therefore, the current Guest calendar timing method can only be said to be relatively accurate. If the standard time is 365.2422 days calculations, the actual difference is 365.2425-365.2422 = 0.0003 days
That is to say, the time of the current Guest calendar will not change the time of the sun, and the number of days we actually timed away from the number of days after approximately 3,000 years.
However, this is only theoretical calculation results, and the time of the earth's publicity can only be said to be relatively stable, and each year may change due to the external force or internal force of the universe, and another 3000 years is a long period of time, so no one will care about this error. .
