How old am I if I was born on September 15 2017?

How old am I if I was born on September 15 2017? It is a commonly asked question. All of us want to know our age, regardless of whether we are young or old. To know how old we are is also needed in some cases. Somebody can ask us about it in school, work or in the office. So today is the day in which we are going to dispel all your doubts and give you an exact answer to the question of how old am I if I was born on September 15 2017.

In this article, you will learn how you can calculate your age – both on your own and with the use of a special tool. A little tidbit – you will see how to calculate your age with an accuracy of years, years and months and also years, months and days! So as you see, it will be such exact calculations. So it’s time to start.

I was born on September 15 2017. How old am I?

You were born on September 15 2017. We are sure that if somebody will ask you how old you are, you can answer the question. And we are pretty sure that the answer will be limited to years only. Are we right?

And of course, the answer like that is totally sufficient in most cases. People usually want to know the age given only in years, just for the general orientation. But have you ever wondered what your exact age is? It means the age given with an accuracy of years, months and even days? If not, you couldn't have chosen better.

Here you will finally see how to calculate your exact age and, of course, know the answer. What do you think – your exact age varies significantly from your age given in years only or not? Read the article and see if you are right!

How to calculate my age if I was born on September 15 2017?

Before we will move to the step by step calculations, we want to explain to you the whole process. It means, in this part we will show you how to calculate my age if I was born on September 15 2017 in a theoretical way.

To know how old you are if you were born on September 15 2017, you need to make calculations in three steps. Why are there so many steps? Of course, you can try to calculate it at once, but it will be a little complicated. It is so easier and quicker to divide the calculations into three. So let’s see these steps.

If you were born on September 15 2017, the first step will be calculating how many full years you are alive. What does ‘full years’ mean? To know the number of full years, you have to pay attention to the day and month of your birth. Only when this day and month have passed in the current year, you can say that you are one year older. If not, you can’t count this year as a full, and calculate full years only to the year before.

The second step is calculating the full, remaining months. It means the months which have left after calculating full years. Of course, this time, you also have to pay attention to your day of birth. You can count only these months, in which the date of your birth has passed. If in some month this date has not passed, just leave it for the third step.

The third step is to calculate the days which have left after calculating full years and full months. It means, these are days which you can’t count to full months in the second step. In some cases, when today is the same number as in the day in which you were born, you can have no days left to count.

So if you know how it looks in theory, let’s try this knowledge in practice. Down below, you will see these three steps with practical examples and finally know how old you are if you were born on September 15 2017.

Calculate full years since September 15 2017

The first step is calculating full years. So you were born on September 15 2017, and today is December 21 2024. First you need to do is checking if the 15th of September has passed this year. This is the 21th of December, so September was a few months before. It means you can calculate full years from the year of birth to the current year.

So how does the calculations look?

2024 - 2017 = 7

As you can see, you require subtracting the year of your birth from the current year. In this case, the result is 7. So it means that you are 7 years old now!

In some cases it will be sufficient to know your age only in years, but here you will know your exact age, so let’s move on.

Remaining months since September 15 2017 to now

The second step is to calculate full, remaining months. You were born on September 15 2017, today is December 21 2024. You know that there are 7 full years. So now let’s focus on months. To calculate only full months, you need to pay attention to the day of your birth. It’s 15th September. So now you require checking if 21th December has passed this year. If today is 21th of December, it means yes, 15th of December has passed. So you will calculate full months from September to December.

To make calculations, it will be better to mark months as numbers. September is the 9th month of the year, so mark it just as 3, and December is the 7th month of the year, so mark it just as 7. And now you can calculate the full, remaining months.

The calculations look as follows:

12 - 9 = 3

So you need to subtract the smaller number, in this case 3, from the bigger one, in this case 7. And then you have the result – it is 3 months. So now we know that if you were born on September 15 2017 you are 7 years and 3 months old. But what about days? Let’s check it!

Days left since September 15 2017 to now

The third, last step, is calculating the number of days which have left after previous calculations from the first and second step. There is no surprise, this time you also need to pay attention to the day of your birth. You were born on September 15 2017, today is December 21 2024. You have calculated full years, from 2017 to 2024, and full months, from September to December. It means you need to count only the days from December.

You were born on the 15th. Today is the 21th. So the calculations will be quite easy. You need to just subtract 15 from the 21 to see the number of days. The calculations will look like this:

So there are 7 full days left.

So to sum up – there are 7 full years, 3 full months and 7 days. So it means you are 7 years, 3 months and 7 days old exactly!
