Why is the leap year in 2023 a normal year or a leap year?
2023 is a normal year in the Gregorian calendar, but it is a leap year in the lunar calendar, because there is a leap month in this year, and it is a leap second month.The probability of leap February is very large, because there is a time error in the timing method of the lunar year, so every two or three years, a leap month will be added to adjust the time difference.
What is the meaning of the intercalary second month
In order to make the lunar calendar and the Gregorian calendar match the seasons and the seasons, our ancestors used the method of "adding intercalary months" to "adjust the surplus and deficiency".Seven leap months are set up in the middle of the year - because the total number of days in 19 tropical years is basically the same as the total number of days in 19 normal years plus 7 leap months.Therefore, the lunar calendar stipulates that an intercalary month is set every two or three years.In a year with a leap month, the lunar calendar is 13 months, totaling 383.8978 days.In the lunar calendar, there are two Februarys, and the second February is the leap February.The frequency of Leap February is second only to Leap March, with a moderate frequency around the 21st century, generally occurring once every 19 years (such as 2004 and 2023).Since then, the frequency of intercalary February has gradually decreased and it has become a rare intercalary month, which occurs once every century in the 25th to 28th centuries.
