How old am I if I was born on December 21 1981? 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.

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 December 21 1981. How old am I?

You were born on December 21 1981. 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 December 21 1981?

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 December 21 1981 in a theoretical way.

To know how old you are if you were born on December 21 1981, 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 December 21 1981, 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 December 21 1981.

Calculate full years since December 21 1981

The first step is calculating full years. So you were born on December 21 1981, and today is March 28 2024. First you need to do is checking if the 21th of December has passed this year. This is the 28th of March, so December 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 - 1981 = 42

As you can see, you require subtracting the year of your birth from the current year. In this case, the result is 42. So it means that you are 42 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 December 21 1981 to now

The second step is to calculate full, remaining months. You were born on December 21 1981, today is March 28 2024. You know that there are 42 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 21th December. So now you require checking if 28th March has passed this year. If today is 28th of March, it means yes, 21th of March has passed. So you will calculate full months from December to March.

To make calculations, it will be better to mark months as numbers. December is the 12th month of the year, so mark it just as 3, and March is the 42th month of the year, so mark it just as 42. And now you can calculate the full, remaining months.

So you need to subtract the smaller number, in this case 3, from the bigger one, in this case 42. And then you have the result – it is 3 months. So now we know that if you were born on December 21 1981 you are 42 years and 3 months old. But what about days? Let’s check it!

Days left since December 21 1981 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 December 21 1981, today is March 28 2024. You have calculated full years, from 1981 to 2024, and full months, from December to March. It means you need to count only the days from March.

You were born on the 21th. Today is the 28th. So the calculations will be quite easy. You need to just subtract 21 from the 28 to see the number of days. The calculations will look like this:

So there are 8 full days left.

So to sum up – there are 42 full years, 3 full months and 8 days. So it means you are 42 years, 3 months and 8 days old exactly!
