Dear stupid: how many times does the earth rotate in a year?

[Jehanne]

Yeah so as you can see it does travel along a cylindrical path as I previously mentioned, but it doesn't spiral (a spiral requires that gets smaller or larger). I thought including that as an answer for my poll was an especially nice touch through! Although, if I was nice about it I could have worded it to be a correct answer, but I really only wanted 366.x or 367 to be the correct answers.

It seems even more complex than Vsauce's video -- the Earth moves around the Sun, and the Sun revolves around the Galactic center, and the Galaxy is moving with respect to the Andromeda Galaxy and the Local Group, and all those galaxies are falling toward the Great Attractor, which is likely falling toward the Shapley Supercluster.

Many examples proven absolutely, 100% true. Too many in number to be called coincidences

With enough twisting and contorting anything can be made to sound 'true' to the weak-minded.  It is called brain-washing and you have it bad.  Sorry.

 I'll just use a few of the miracles I listed.

So u  seem to think that the knowledge given from a scripture with religious commands and laws, but just happens to have for instance the word "land" mentioned through its 6,236 verses EXACTLY 13 times and the word "sea" EXACTLY 32 times, 32+13=45 13/45=28.89% and 32/45=71.11% THE EXACT PERCENTAGES of LAND AND WATER that cover our planet today, comes from some human being? Or the alphanumerical value of "Al-Hadyd" (The Iron), Chapter 57 of the Qur'an, which is EXACTLY half of the 114 total chapters. With Arabic alphanumeric the H=8 D=4 Y=10 D=4 totaling 26. Isn't it remarkable that the atomic number for iron is, as it always has been, even before the 7th century when the Qur'an was first revealed to mankind, is 26? But then to take it a step further so it can't be called "just a coincidence", when u add the article "Al" meaning The in Arabic, making it The Iron the alphanumerical value of A=1 and L=30 totaling 31 added to the already calculated 26=57 which is also the EXACT number of the chapter of the Qur'an. And to go even one step further. If the Qur'an was cut exactly in half which is at chapter 57 The iron and if the Earth was cut exactly in half showing the Earth's core it consists of molten IRON. Is this something a human being knew in the 7th century when technology did not even yet exist?

What's the difference?

1 rotation

[Anomalocaris]

Very simple question. In the time it takes for the earth to make a complete revolution around the sun (1 year), how many times does the Earth physically rotate?

Rotate in what frame of reference?

This thread is already pretty long, but I don't want to read it.  If others have given the answer, fine, but I want to think for myself.

In Around the World in 80 Days, Jules Verne has a twist ending in which his hero has unknowingly gained a day because of the direction of his travel.  If you think of the Earth as a traveler around the sun, then that means the Earth must either gain or lose one rotation compared to what we know the length of a year to be: about 365.2452 days.

Therefore, the answer should be 364.2425 or 366.2425 depending on whether the Earth's orbit and its spin are in the same direction or opposite.  Since you didn't provide 364.2425 as an option, then I must assume you've already learned that the orbit and spin are in the same direction, and say the answer is 366.2425.

HOWEVER, the sun is orbiting around the center of our galaxy, and the galaxy perhaps is party of a supergalaxy with its own rotation, adding a Jules Verne effect (lol) to our calculations.  I don't think the difference would be enough to change the value at only 3 decimal points. . . but it would change it. So getting an absolute value would, it seems to me, be impossible.

According to Google, a calendar year is either 364 or 365 days.
An earth year is 365.25 days but some sites say 366.25

The 365.25 is correct. That's why we have the leap year. 4*.25 = extra day.

No, it's not correct, at least as an answer to the OP's question.  The question isn't how many DAYS are in a year, but how many times the Earth rotates in a year. These quantities are different.

Is it 366.25 then? Because it's about 4 minutes less than a whole day to rotate and 4 minutes a day for a year is about 24 hours which would be one extra rotation. Is that it?
