A year is the time that a planet (such as Earth) takes to orbit the Sun, that is to make one complete revolution around it.
For Earth, a years is equal to about 365.25 days.
year
one year
It takes 24 hours to complete one rotation and one year to complete one revolution.
One complete cycle of any repeating motion is defined as 360 degrees.
It takes 24 hours to complete one rotation and one year to complete one revolution.

The moon makes one complete orbital revolution of the earth in 27.32 days, and displays a complete cycle of phases every 29.53 days.
One year
It takes about 27 days for the moon to return to it's same position with respect to the Earth, however since the Earth also orbits the sun the moon has to travel around the Earth for about 29 days for it to complete one lunar month.
A solar year is the time that it takes the earth to complete one cycle around the sun. The year is the time taken by earth to complete a cycle around the sun which takes about 365.25 days. So, a calendar year is 365 days and 1 quarter. Every Leap Year (once in 4 years) there is an extra day in February. A year technically is the time taken for a planet to make one orbit of the sun. At that rate, an Earth year is shorter than a Mars year, which is 687 days at a 24 hour day. This will be longer than a year on Mercury, which takes 88 Earth days to orbit the sun.
