Each year is when the Earth has completely revolved around the sun. Each day is when the Earth has completely rotated. It's twirling on the axis's while its moving around the sun. Each month is just what we came up with to keep the amount of days in order. The Earth has nothing to do with it

One Earth year equals how many Earth days?
The exact length, in days, of Earth's true sidereal orbital period is 365.256366 (364 and 1/4 ) days or 1.0000175 years. As this is not a whole number of days, our Earth calender is arranged to have normal years and leap years. We make a normal year have 365 days and a leap year have 366 days. We arrange it so that a leap year happens every 4th year so that extra day makes up for the four 1/4 days we need make the orbit position the same over time.
How many days left till summer?
The Earth is about 4.5 billion years ols and probably has some 5 billion years to go before the sun consumes it. Using the present rotation speed to estimate "days" this would be about 2 trillion days (2x1012 days) This is about 600 million lifetimes.
How long does it take the earth to make one spin?
for a rotation is takes like 365 days or like 365 1/4 days
How long does it take for the earth to make fossil fuels in years at a time?
It takes millions of years for fossil fuels to be naturally formed.
How many hours make a day on Venus?
This question is meaningless. An Earth day would be the same length no matter what planet you are on. An Earth day would be the equivalent of 0.004 Venus days and about the same number of Venus year (it takes a whole year for Venus to go round its orbit). A Venus day is 243 Earth days. That's 243 Earth days to rotate once. Astronomers call this a sidereal day. However there is also the solar day of 117 Earth days.
How many Earth years does Mars need to revolve around the Sun?
It takes Mars 687 Earth days to make one full orbit around the sun. Thus, one year on Mars is equal to 1.88 Earth years (or about 1 year, 10 months, and 22 days).
Why do you have days months and years?
They are just 'natural' time periods. The Earth orbits the sun once a year. The moon orbits the Earth roughly once a month, and the Earth turns on its axis once a day !
How many earth months does it take to make a year on Jupiter?
Jupiter's year is 4,332.71 days, or 142.5 months.
How many orbits around the sun does mercury have in one earth year?
One of Mercury's years is slightly less than 3 months, so Mercury will have 4 of its years in one Earth year.
How many months does it take for the moon to make a complete rotation on its axis?
29 Earth days.
How many Venus days does it take to make one earth years?

How many earth years does it take for mercury to make a revolution?
88 days
How many Earth days does it take Uranus to make one orbit of the Sun?
Uranus takes about 30,687 Earth days (just over 84 Earth years) to make one orbit of the Sun.
How long time to make Indian constitution?
2 years 11 months and 18 days
How long does it take for Mars to make one trip around the Sun?
Mars' rotation is 24 hours, 39 minutes, and 35 seconds (solar day).
How many days make up one year on Neptune in earth years?
a lot! it takes about 10,980 earth days to make up a year for neptune to go around the sun and back!
What planet has a 23 months?
Mars does. It takes 687.0 Earth days for it to make one full orbit around the sun.
