I just realised something about the days in a year (365)

There are 365.25 days in a year...but with Russ's New Jerusalem Calendar I believe there are a million or so...

Well that's obvious...
The earth needs 365.25 days to make a full rotation around the sun...My question is, why does it need these 5 extra days to complete the cycle, instead of 360 days, which would correspond to one degree each day?

Because it takes 365 1/4 Earth rotations to complete one full revolution around the Sun.

Let me re-phrase the question:

Which factor is the one responsible for the 5 extra days needed for earth to cycle around the sun???

We will eventually experience the 360 day rate though...

"As for what the rotation rate of Earth before - we don't have precise dates before 650 million years ago. The recession rate of the moon from the Earth has actually increased since that time, perhaps due to resonance effects (in fact, if we did linear extrapolation of the current recession rate back to the formation of the Moon, the Moon would have been inside Earth's Roche Limit at formation!). In any case, the day length was around 21.9 hours 650 million years ago, from the reference linked below (courtesy of an email from David Catling). In any case - his estimate of the daylength 3-4 billion years ago is bolded below"

Ok, here is the answer:

The earth has to account for an extra 5 days each year in it's cycle arround the sun, due to the phenomenon of the precession of the equinoxes. The precession produces the phenomenon of the backward movement of the sun through the ecliptic. This means, for example if we take as the start of the year the spring equinox, 21st of March, that the sun will rise after 360 days not exactly in the same spot as it did last time, but it would need 5 extra days to reach the degree that he was on the last time. These 5 extra days, account for a backward movement of the sun of 1 degree through the ecliptic each 72 years (5 x 72 = 360 days).

Now since ancient civilizations were aware (as they were the first to appoint 360 degrees in a cycle) that the cycle of the earth around the sun was larger than 360 degrees, they could have easily identified the phenomenon of precession just in one year...

Thanks for sharing.

Watch me blow the minds of people that think randomly adding up numbers until you come up with one that means something to you.


365, 3+6+5 = 14

14, 14/2 = 7

7 = first page I pulled up google questioning the meanings of the level 7...

The seven indicates the senses of a change after an accomplished cycle and of a positive renewal.

So there you have it, the number of days in a year turns into 7 which means in jist the end of a cycle or a new year. See how easy it is?












P.S. JUPITER IGNITION

And the "work day" was only 6 hrs instead of 8 now...God those were the days :)

cycle this FFS

you will be hard pressed to find a perfectly circular orbit anywhere and the degrees mean nothing

Earths orbit (a year) is currently 365.25 days (8764.8 hours). Earth's spin (day) is currently 24 hours.

Several hundred million years ago Earth's spin was once per 20 hours. Thus its orbit took 438.24 earth days.

The so called extra '5' days has more to do with how rapidly the earth rotates on its axis (its day).

Several hundred million years from now earth's day will be 30 hours long, thus its orbit will be 292.16 days long.

Word:: That totally makes sense.

You seem to be confusing degrees measuring a circle or something, the the amount of times the earth spins around in total to complete one spin around the sun.

Some planets could do this in DAYS, so don't confuse with degrees.

Yea I guess you are right. I was thinking that a day a degree isn't necassarily a law of nature or something.

could've just said we don't go in perfect circles :P

Moon added 5.25 days?

Helix forward around the sun...

nice
