Popular science about leap year
A leap year is a year with one more day than an ordinary year, that is, February has 29 days instead of 28. The rules for determining leap years are as follows:
1. A year that is divisible by 4 but not divisible by 100 is a leap year.
2. A year divisible by 400 is also a leap year
3. All other circumstances are normal years.
According to this rule, 2015 is not divisible by 4, so it is an ordinary year. And 2016 is divisible by 4 and not divisible by 100, so it is a leap year.
