## I was born in December 2009. How old am I?

Sometimes all of us just wonder about our age. So if you think about your age too, don’t worry – it is totally normal. Thinking about age need not imply a question asked by somebody or filling in documents. Sometimes we wonder how old we really are when we feel older or when it’s getting closer to our birthday. Such thinking can take place also when we get nostalgic for past years.

Regardless of the reason why you are wondering how old you are, you can be sure you are in the right place. Here you will finally find the answer. Our how old calculator is a tool dedicated to such questions. For those of you who are more inquisitive, we also prepared a part about calculating your age on your own, so you can see the whole process.

So now, without any further ado, let’s start with calculations!

## How to calculate what is my age if I was born in December 2009?

Calculating your age wouldn’t be problematic if you want to calculate only years. This is the easiest calculation then – you just need to subtract one number from another. But the situation looks different when it comes to the calculation of your age with an accuracy of years and months. And such a case takes place now, when you want to calculate your age if you were born in December 2009.

**To make the calculations as simple as possible, we are going to divide them into two parts. Part one concerns calculating full years.** You need to pay attention here. You can’t just subtract the number of your year of birth from the number of current year. You have to calculate only full years. So if now the month of your birth has not passed, don’t calculate the last year. Of course, we know that it can seem complicated, but it doesn’t. We are going to prove it to you in the practical part.

**But now let’s focus on part two. In this part, you need to calculate the remaining months.** To make it, you need to calculate the remaining number of months after calculating the full years. The years you will calculate by checking the number of years between your month and year of birth and the same month in the current year (or in the previous one, if in this year this month has not yet come). The months you will calculate by checking the number of months between the month of your birth in this or previous year and the current month.

And these are the 2 steps which you need to take to get the answer to how old am I if I was born in December 2009. If you want to know how the calculations will look in practice, see the next part of the article. We are sure that then you will finally see that this method is not as complicated as it can seem at first sight.

## Calculating full years since 2009

**The first thing you need to do to know how old you are if you were born in December 2009 is to calculate the full years you are alive. **Remember – the month of your birth is so important in this case. So if you were born in December, check if the December in the current year has passed.

For instance, now it is November 2024. So it means December has passed this year. You can just subtract the year of your birth, that is 2009, from the current year, that is 2024. The calculations will look as follows:

2024 - 2009 = 14

**Remember **– if the month of your birth has not passed this year, subtract the number of the year of your birth from the number of the previous year, not current.

So as you can see, the result is 14 full years. If you need your age given only in years, it could be the answer – I’m 14 years old.

But if you need a more exact result, that is your age given in years and months, you need to check the remaining months too. How to make it? Just check it in the next paragraph.

## Calculating remaining months

**To calculate the remaining months, you need to know your month of birth and the current month.** If you were born in December 2009, and now it is November 2024, it means you need to know how many months are between December and November.

December is the 12th month of the year, and November is the 11th month of the year. Thanks to knowing these numbers, you can just subtract the smaller one from the bigger one to get the answer. So, how to make the calculations? Have a look:

As you can see, these calculations are not complicated either. The answer is simple, just 11 months. So what is your age in accuracy of years and months? See it in the next paragraph.

## Your age if you were born in December 2009

**To get the answer to the question of how old am I if I was born in December 2009, you need to combine the two answers from the previous parts **– it means your age in years and remaining months. Both of these numbers together will give you the exact answer you need.

So here is a quick reminder – the first answer was 14 years, the second was 11 months. So after summing up, at the current date, it means November 2024, **you are 14 years and 11 months old.**

What do you think about this result? We hope that getting it was not so difficult for you. The key to know your age in years and months, quickly and easily, is to divide the calculations into two parts. First calculate only full years, second calculate remaining months.
