This formula takes into account the existence of leap years, as well as the actual number of days per day and the actual number of days per month. For example, if you want to calculate how many years have passed between March 3, 2000 and May 2020 1, you can follow the following steps:
Calculation year: (2020-2000)+(5-3)/12+(1-3)/365 = 20 years +0 years +(- 1)/365=20 years-/kloc- Determine the year: According to the above calculation, the interval between the two dates is about 20 years.
It should be noted that this formula can only give an approximate year and cannot be accurate to the specific month and day. If you need more accurate calculation, you can consider using special date calculation software or function.
