How many days in a year

FACTS

We all know that how many days are there in a year. But really is it the answer really? Just a simple whole number is the amount of time taken by earth to go round the sun? It might not be exactly. But for the sake of simplicity, we do accept a widely accepted common number and that makes everything go. But in this article, we are not going to do that. We will find out the exact number of days that actually exist in a single year. So, how many days in a year?

Let’s find out.

There are various ways which we can use to get to the correct answer. And we will use a number of techniques for this too as usual.

The widely commonly accepted number is actually 365. YES. In a year, there exist 365 days of a total in one complete year. But when it comes to the average terms, the value increases a bit. As in relation to normal years, we also have leap years. And in such a year, there is one extra day for the month of February, totaling out at 29 from 28. Rest all remains the same. On whole, 365 is the depicted total number of days in traditional calendars. Not exactly, but calculating the total number of days will give you the number. The leap years are not actually mentioned specifically but it can be detected out from the last date of February. And that is 29, one extra date as opposed to usual 28 on regular. This depicts a leap year and the total number of days goes to 366. A leap year only occurs once in four times. Three times the normal year along with a leap year. This is the common convention, that gives us 365 and 366 days for years.

But what will you answer when someone asks you the same question that we have raised in this article? 365 or 366? You don’t even know which of the year he/she will question you about? This also creates a problem. There are two values always in the count. You just can’t make an average of the two and give out the answer. That is still mathematically inaccurate.

We will use a simple method to get to the actual right answer along with uncommon fractional value.

First, we count the number of days in every month and add them up for every specific year. That will do it. In a normal year, there are seven months of 31 days each, so seven times 31 is equal to 217. And there are four months of 30 days each. So, 30 times four gives us 120. And there is the month of February which either has 28 days (on a normal year) or 29 days (on a leap year). So, we add either 28 or 29 to the sum of 217 and 120. This will give us the total amount of days in a year. Similarly, the sum of 217, 120 and 28 gives us 365 which is the number of days in a normal year. And 217, 120 and 29 gives a total of 366 days which is exactly the same for total days in a leap year. But we still have two values but we don’t know which one to use for usual.

So, how many days in a year? It’s either 365 or 366.

We are gonna solve it for a single true value.

We do know that once in four years, three of them are normal years and one is a leap year. So we average out the actual number using these data. So, we multiply 365 three times (as it comes three times) and add 366 to it. This will give us the total number of days in a total of four years. Which sums up to 1461. And this is the total number of days occurring in every four years, so it is a constant value from the beginning. Dividing this total by four will give us the exact number of days for each year. So 1461 divided by 4 gives us a fractional value of 365.25 which is similar to the number of days in a normal year. But it is 25% more than a normal year, but 75% less than a leap year.

This is the actual value of the total number of days in a common year.

Denying the fact that we can’t say this is wrong, this is the true value mathematically. But conventionally we say it’s 365, which is actually wrong. But nobody cares. Averaging always gives out the actual value.

Controversy for the extra.25

The earth actually doesn’t take exactly 365 whole days each of 24 hours to revolve around the sun. The fact that 24 hours is exactly 23 hours, 56 minutes and 4 seconds. Nothing is whole in existence except the natural numbers and whole numbers. There are even separate floating point processors for computation to deal with fractional number calculations. So, the thing is serious. Back to our case, the extra .25 is actually a time limit for the earth to complete the one whole rotation. This actually counts up in a day, so .25 or 25% of a day’s time in 24 hours, or 6 hours or exactly 5 hours, 59 minutes and 1 second (if we take the exact value of hours in a day). This small time along with the whole 365 days is the total time of a year. And same time for the earth to gain its round. But mostly for sake of simplicity, this is not at all depicted in common studies, unless needed which prevents more complexities. But on astronomical studies and calculations, the same exact value is used. This extra time gets counted four times for every four years and is added in the month of February. And thus it has 29 days.

So, How many days in a year? It’s exactly 365.25 days or just 365 days and 1/4th of the day.

Now you know it.
