Oh, dude, it's because a year is the time it takes for the Earth to orbit around the sun. And like, it just so happens that it takes about 365.25 days for that to happen. So, we round it down to 365 days for simplicity's sake. Kinda like how we round up when splitting the bill at a restaurant, you know?

A year is about 365 days long because it takes approximately 365.24 days for the Earth to orbit the Sun. This is why we have leap years every four years to account for the extra 0.24 days, making the average year 365.25 days long.

It isn't. There are slightly more than 365 days in a year. A day it the time it takes for the earth to rotate about its axis. A year it the time it takes the earth to orbit the sun, being roughly how many 'spins' our planet makes on its axis during one full orbit of the sun.

That's the length of time it takes the earth to complete one orbital revolution

around the sun. That period of revolution is also connected ... for reasons perhaps

too complex to discuss just now ... to the period of a complete cycle of seasons.

It's actually closer to 365 and 1/4 days long (hence the leap year).

We seem to be "Children of the Sun" as it takes the Earth 365 days (actually a little less) to circle the Sun, our nearest star. It also happens to take the Earth about 24 hours (a little less, actually) to revolve or spin one complete turn.

That is a Julian year - a year in the Julian calendar, which has an extra leap day every 4 years. We use the Gregorian calendar with a year of 365.2425 days. That is the number of days it takes for the Sun to return to the same place in the sky each year. In our Gregorian calendar there are 97 leap years in every cycle of 400 years.

The number of days it takes to go round is determined by the average distance from the Sun. For every 1% increase in the average radius of an orbit, the 'year' increases by 1.5%, which is one of Kepler's laws.

We are at the distance we are purely by chance, and the conditions suited the development of life, which is why we are here. But at this distance the length of our year is fixed by Kepler's laws.

It is actually 365.25 days long because it takes that long to orbit the Sun once. To make up for the quarter day, we add an extra day every 4 years in a leap year. The 0.25 is actually slightly too big, so we forego the leap year every so often to adjust.

There are 365.25 days in a year. Not 365.

This is because: The amount of time it takes the Earth to complete a complete revolution around the Sun is 365.25 days.

A year is the time that it takes for Earth to go around the sun. The Earth always travels around the sun on the same path and at the same speed.

It's Not. It's about 365.24 days.
