Definition and calculation of leap years
A leap year is a year in the Gregorian calendar year that is divisible by 4 but not by 100, or is divisible by 400.
In the Gregorian calendar, there is a leap year every 4 years, which is used to adjust for the difference between the time the Earth orbits the sun and the calendar year.
Examples of the impact of leap years and calculations
Leap years have an impact on calendars, schedules, and timing, such as February 29 which only occurs in leap years.
Leap years are calculated in a simple way, a year that is divisible by 4 but not divisible by 100 is a leap year, but a whole century year needs to be divisible by 100 and not divisible by 400 to be a common year.
The year 2024 of the Gregorian calendar is a leap year, and the year of Jiachen in the lunar calendar is a common year
The year 2024 in the Gregorian calendar is a leap year, with 29 days in February, and a total of 366 days in the year.
The lunar calendar is formulated according to the phases of the moon and the movement of the sun, and there is no leap month in the first year of the lunar calendar, which is a normal year, with a total of 354 days in the year.
Difference Between Gregorian Calendar and Lunar Calendar
The Gregorian calendar is based on the Earth's orbital cycle around the Sun, adjusting for time errors by setting leap years.
The lunar calendar is formulated according to the phases of the moon and solar terms, and adjusts the difference between the moon phase and the return year by setting leap months.
The importance of leap years and lunar calendars
Leap years are used to adjust for the difference between the calendar and the actual time, ensuring that the calendar is accurate.
The lunar calendar maintains the accuracy of the lunar calendar by setting leap months to adjust the difference between the moon phase and the return year.
By understanding the relevant knowledge of leap years and the lunar calendar, you can better understand the adjustment mechanism and time calculation method in the calendar, and deepen your understanding of the concept of time.
