How many days are there in a leap year?

People nowadays use different unit of time, like, second, minute, hour, day, month and year to describe the length of time, which is clear to everyone. And there is a decade, which stands for a period of 10 years. Then we have a century, which is a period of 100 years. So how many days are in a leap year?

1 leap year is equal to how many days? A leap year can also be called a bissextile year or an intercalary year, which consists of 366 days. Because every four years, there is one more day added in February, that is 29 days (28 days in February normally).

Then it all leads to 366 days in a leap year. But have you ever wondered why there is a leap year, or why are there 366 days in a leap year?

Why are there 366 days in a leap year?

To be more accurate, there are 365.242199 days in a year, which can be round up to 365.25 days in a year on average. Why is that? Because it takes the earth 365.242199 days to orbit the sun, which makes a year.

But we usually use the number 365 days for a common year because it’s easier to remember. And all the numbers left – 0.242199 days – will slowly add up and that’s why there are 366 days in a leap year.

So we will talk about how to convert leap years to days.

How many days is 1 leap year?

# CASE 1: 366 days in a leap year
· 1 year = 366 days
· 1 year = 1 y x 1 year = 1 x 366 d = 7366 days
1 year = 1 x 1 y = 1 x 366 d = 366 days
1 leap year = 366 days

(PS: minute= m, second= s, hour= h, day= d, year= y)

# CASE 2: 366 days in 1 leap year
· 1 leap year = 366 days
· 2 leap years = 12 y x 1 year = 2 x 366 d = 732 days
2 leap years = 2 x 1 y = 12 x 366 d = 732 days
2 leap years = 732 days
