Why is there only 364 days in a year instead of 365 days?

Answer 1

It doesn't.

Earth's rotation around the Sun is about 365 days, six hours, and some - every year.

But since counting quarter-days would be so awkward, people cam up with the idea of adding one whole day every 4th year instead, to keep the calendar synched with the seasons.

Works just as well and is a lot simpler.

For those who need to be really accurate, there are even leap minutes and leap seconds that gets added every now and then.

Answer 2

It is because the earth rotates around the sun but slower during the year so therefore, there are about 364.7 days in the year and that adds up into a leap year.

Wrong. You got the wrong number of whole number of days in a year. It's 365 days. Not 364 days.

Answer 3

Because the earth takes 365 and 1/4 days to revolve once around the sun.

Answer 4

This is because it takes the Earth 365.25 days to make one revolution around the sun. After 4 years a new day must be put in or eventually the seasons would be in the wrong places.

Answer 5

Because it takes the earth about 365.24219 days to orbit the sun.

Answer 6

Because the Earth actually takes about 365,.25 days in a year to orbit the Sun and so every leap year we add an extra day to the year.
