Days in a year....?

Question

ok there is 365 days in a year. there is 52 weeks in a year and there is 7 days is a week. However when you multiply 52 x 7 it equals 364 ...where is that extra day coming from?????????

Answer 1

There is an extra quarter day each year....which is why every four years we have leap year

Answer 2

We have two sets of measurements that we are trying to model together to provide a continuous calendar that is always accurate.

First, the amount of time that the earth takes to revolve on its own axis is what we call a day. The next time standard is how long the earth takes to revolve around the sun. We call that a year. It just so happens that it takes, as others have already written, approximately 365.25 of our previously defined days to do that.

For simplicity, we could have chosen 364 days in a year, but then instead of adding 1 day every 4 years, we would have to add 5 days. Or, we could make a day slightly longer so that we would have 364 of these "new" days each year. But then, the sun would rise say at 5:00 a.m. in January but by the end of May, the sun would be rising at 5:00 p.m. So, the solution to have 365.25 days is a pretty good working solution. Since it is not 365.25 exactly, I believe there are instances where a day must be added every 400 years or so to keep the calendar from drifting.

Answer 3

The number of weeks in a year is not exact. There are 52 and a fraction weeks in a year. If it were exact, then January 1st would always fall on the same day of the week.

Similarly, there are 365 and a fraction days in a year. That's why every 4 years, we have a leap day (and why every 100 we don't unless the year is divisible by 400).

Given the way leap years are handled, it works out to 365.2425 days in a year, so it comes out to 52.1775 weeks in a year. (On average

Answer 4

There are 52 weeks and 1 and a 1/4 days in every year;

Answer 5

There are 365.24 days in every year.
If you divide 365.24 days by 7 week days, you get 52.18 weeks.
These are not nice, round numbers, so we round them to 365 and 52.
Then every 4 years we add 1 extra day to the calendar to make it look a little nicer.
I've even made my numbers look nicer by rounding 365.242199 days to 365.24 and 52.1771428571 weeks to 52.18.

You're right, 7 days x 52 weeks equals 364 days. That was a very good observation! There is no extra day, though, it's just our human need to wrap everything up into nice packages.

Answer 6

because 365 cannot be divided by 7 so the day it starts in a year is the same as the day that ends in a year always(except for a leap year which the last day of a year is one day after the first day of the year) example :2007 january 1st: monday, December 31st: monday that adds up to 365 days a year. you get 364 by 52x7 if the day that starts in a year is one day after the day that ends in a year. [example: january 1st:monday, december 31st: sunday which adds up to 364 days(which will never happen)] so that is why.(I have no idea why people are saying the answer for a leap year this question is about every year).

Answer 7

A year is actually 364 and 1/4 days. It's just that we round up to a day to make it 365 days.
There is some ancient civilization influence too though.

Answer 8

There are 365 days in a year. The weeks aren't quite even. A leap year has 366 days.

Answer 9

Days in a year....?

Answer 10

well if you figure that a month is technically four weeks, that would only be 28 days in a month, but some months have 30 and some have 31. if you divide 52 weeks by 4 weeks, which gives you 13 months, we only have 12 months in a year.
