Chronological Age Calculator [Easy Calculate Person's Age] - Calculators.io (2024)

Your chronological age represents how old you are. By definition, this is the number of years you’ve lived starting from the time of your birth. A person’s chronological age would determine his eligibility for school, for work, and for retirement. To find your chronological age, subtract your date of birth from the current date. When you subtract dates, it’s similar to when you subtract numbers. The only difference is that when you subtract months, you only use numbers 1-12 and for days, you only use numbers 1-29, 30 or 31. To get a more specific chronological age down to the number of seconds, you can use this chronological age calculator.

How to use the chronological age calculator?

Using an age calculator online is an easier and convenient way for you to get your exact chronological age. Unless you want to perform the calculation manually, this online tool can save you a lot of time and money. Here are some steps to use this calculator:

• First, enter your Date of Birth starting with the day, the month, then the year.
• The Age on this Date is already entered for you, but you can also change this date if you want.
• After entering the dates, the chronological age calculator will automatically generate your chronological age giving you the Years, Months, Weeks, Days, Hours, Minutes, and Seconds.

How to calculate chronological age

Before you use a Pearson age calculator or an age calculator online, it’s important to understand what your chronological age is first. Your chronological age refers to the exact amount of time you’ve lived. In other words, it’s how many days, months, and years you’ve lived no matter what type of lifestyle you have. Whether you follow a healthy diet and exercise regularly or you live a sedentary lifestyle, your chronological age will only change as time goes on.

The rate at which we age differs from one person to another. While some people age at a very rapid rate, the luckier ones age at a more gradual rate. That’s why some people look older than they are while others look really young even though they’re already chronologically old.

Most people confuse their chronological age with their biological age, but these are two very different things. Your chronological age refers to the amount of time you’ve lived from the time of your birth. But your biological age refers to how long it would be before you would start to suffer decline related to your age and your body would start to die. Let’s explain this by using an example.

For instance, we have two 45-year-old women. One of them is very lazy, doesn’t have any motivation to exercise, drinks a lot of alcohol, eats unhealthy foods, and smokes a lot. But the other one follows a healthy diet, exercises regularly, has a positive disposition, and looks after her overall health and wellbeing. The second woman may drink but only on occasion, and she doesn’t stress herself about things she cannot control. If these women had the same date of birth, that would mean that they have the same chronological age. However, they would have a very different biological age. Because of the way she lives her life, the first woman would have a very weak physique which means that she may already be about 57-years-old biologically.

For the second woman who takes better care of her body, her biological age could only be at 34-years-old or so. The first would be 12 years older than her chronological age while the second woman would be 11 years younger biologically.

This chronological age calculator will calculate your age all the way down to the second from your testing date. It does this by subtracting your date of birth from the test date. It’s a very convenient tool for you to use, especially when you need to get your chronological age in a pinch.

However, there may also be times when you won’t have access to a Pearson age calculator or any other type of online tool. In such a case, you can manually calculate your chronological age. To do this, let’s have another example.

For instance, a person wants to get his chronological age, and his date of birth was November 30, 1996. For this example, let’s say that he checked his chronological age on August 7, 2013. To get his chronological age, you should first create a subtraction problem by laying out all the information numerically.

For August 7, 2013, the numerical values would be 8, 7, and 2013

For November 30, 1996, the numerical values would be 11, 30, and 1996

First, start by subtracting the numerical values of the days. But in this case, the number for the test date is less than the number for the date of birth. Therefore, you need to borrow 30 days (1 whole month) from the numerical value of the month. This means that for the test day, the number of days would be 37 while the number of months would be 7. After borrowing, you can now get the value for the days:

37 – 30 = 7 days

The next values to subtract are the months. Again, the number for the test date is less than the number for the date of birth. So you can borrow 12 months (1 whole year) from the numerical value of the years. Then the number of months would be 19 while the number of years would be 2012 for the test day. Now you can get the value for the months:

19 – 11 = 8 months

Finally, you can subtract the numerical values of the years without having to borrow any numbers:

2012 – 1996 = 16 years

After subtracting all of the numerical values, we now have the age of the person in our example which is 16 years, 8 months, and 7 days. Of course, if you compute manually, you won’t get your chronological age all the way down to the number of seconds. That’s why it’s a lot easier and more convenient to use our chronological age calculator to get the exact value you’re looking for.
