Why is it 365 days?

Question

Why do we have 365/366 days in a year? Why not more,is because at that time we could count uptil 365 only? thanks. anjum

Answer 1

A day is the amount of time it takes the earth to rotate 360 degrees. A year is the amount of time it takes for the Earth to travel around the sun, 360 degrees. Since you are using Days as a standard of time measurement, it takes about. 365 and 1/4 day for the earth to take its journey around the sun. Every 4 years a day is added to the year to take into consideration of that 1/4 day. But that is not accurate. There is still error. Every 100 years, the 4th year will not be 366 but 365 days to compensate for the error since it is not exactly 1/4 a day in error. But because there still is an error in the 100 year rule, they have another rule that says every 1000 years, you can go ahead an ignore the 100 year rule and have a leap year.

Our definition of time is based on movement. The movement of the spin of the earth. The movement of the earth around the sun, or the lunar cycle of the moon traveling around the earth. It wasn't until the invention of clocks and other time pieces that allowed us to measure time with a mechanical device that the average person can know the time, but forget the connection.

Answer 2

Actually there are 365.242199 days in a year. That is the amount of time that it takes for the Earth to make one circuit around the sun. Every four years we add an extra day to the calendar to catch the 1/4 day that we missed during the previous years.

For someone else who answered. The Earth makes a complete rotation on its axis ever 24 hours (give or take a few micro-seconds here and there). It does not take 365 days for the earth to rotate.

Answer 3

The time it takes for the Earth to revolve around the Sun is 365.24... (I forget the exact fraction). Thus a year is set to 365 days (there can't really be a partial calendar day) with a leap year every 4 years (with exceptions, but that gets complicated). This way the calendar will only need to be reset every couple thousand years, as opposed to every couple hundred years like it had been before Pope Gregory had the current calendar system commissioned.

Answer 4

As stated before me, the earth needs just less than 365.25 days to complete one orbit around the sun. (Within that orbit, the earth completes an axial rotation every 24 hours, or "1 day.") That extra quarter of a day is made up for during the leap year, which occurs every 4 years *except for those years that are multiples of 400.* So, while 1996 and 2004 were leap years, 2000 was not - this is because of that "just less than 365.25 days" figure.

Answer 5

Intresting question, It's because the number of rotations the earth makes during it's rotation around the sun. It makes 365 spins when it makes 1 way around the sun.

Answer 6

Because it takes that many days for the earth to make a complete orbit around the sun.

Answer 7

Actualy years in the past they did not all have locks on the doorways. I keep in concepts it being an merchandise in the information because for quicker or later they were going to close each and each of the shops in the state. they had to bypass and deploy locks on the doorways of a honest type of the shops. i imagine locks are required now for motives reported above. also if there is against the law they prefer to fasten up the keep so no one is accessible in before investigators can research the scene.

Answer 8

It's the amount of days it takes the earth to make one revolution around the sun.

Answer 9

Because that is how long it takes the earth to make one circuit in its orbit.

Answer 10

Because that's the way it is.
