So first things first. The first part will be dedicated to calculating on your own, the second part will be dedicated to our online calculator. So read the whole article or just pick the paragraph which you need to get the answer quickly. Let’s start!

Calculate your age from two dates on your own

Calculating your age from two dates on your own may be understood in two different ways. The first way is calculating from two exact dates, it means dates including day, month and year. The second way is calculating from two dates, but only including year. And as you can imagine, the second version is easier to calculate on your own. That’s why we are going to start with this one.

So if you have two dates in years, you need to check which one is smaller and then subtract this date from the bigger one to get the results in just years. For example, if you were born in 1997, and now it is 2021, you need to subtract 1997 from 2021. That’s it. So have a look at the calculations:

2021 - 1997 = 24

So after calculating your age from two dates, you can see that you are 24 years old now.

But what if you want to get the more appropriate result? Of course, it is possible to calculate age from two exact dates too. Let’s suppose you were born on 6 December 1997, and today it is 16 December 2021. How to calculate your exact age now? Please follow the steps down below:

The first step – check if your birthday has passed this year. In this case the answer is yes, the 6th December 2021 has passed in 2021 yet. So you can subtract 1997 from 2021. If your birthday hasn’t passed, subtract the year of your birth from the previous year, in this case it will be 2020.

2021 - 1997 = 24

The second step – check if there are any full months left. In our case the answer is no, because your birthday is in December, and now it is December too. So now you don’t need to calculate anything.

0 months

The third step – check if there are any full days left. In our case the answer is yes, because you were born on 6th December, and today it is 16th December. So to know how many days are between these two days, you need to subtract 6 from 16. Have a look:

16 - 6 = 10

So there are 10 days left.

The fourth step – sum up all results from the previous steps. After making it, you will know the final result.

So you are 24 years and 10 days old.

As you can see, calculating age from two exact dates can be a little tiring. That’s why we prepared an online calculator for you.
