Age Calculator


The exact age calculator is the tool you need if you want to measure your own or someone else’s age with pinpoint accuracy. However, it’s not just limited to calculating people’s age.

As the name suggests, it is used to simply calculate age, generally of anything or anyone. You can measure your own age, your dog’s age, your car’s age and of anything.

How to know “How Old AM I”?

People often wonder “how old am I!” or even “how many days old am I!” Well, you can have a rough estimate of the age of an object or a person if you know their date of manufacture and date of birth respectively. However, one can’t have a precise measurement of the data up to fractional accuracy.

We humans, unlike computers and calculators, are very bad at doing complex calculations and information processing in our minds especially ones involving numbers and the larger the computations, the larger the potential for human error.


Stuck with finding age on a job form?

Consider this, you apply for a job in a company that requires you to fill out a form where you have to mention your age with fractional precision including the number of days, hours and minutes in addition to years and months. Now you’d find yourself in the middle of a problem.

It is a special case where you know at what time you were born in addition to the date and day. Now calculating all the way from the date and time of your birth to the present day and time with each minute that you spend calculating it manually is only adding to your age.

It makes it nearly impossible to calculate your age manually. We developed how old am I calculator exactly for reasons so that you can get the precise answer and that too, without taking more than 3 seconds or so.


How to calculate my age?

First we’d like to mention that to maximize user convenience, our tool is free to use and does not require user registration or subscription in any form. This calculator has been developed solely for the purpose of facilitating accurate birthday countdown.

Although there are other methods out there as well that you can use to calculate age with reasonable accuracy for instance, by using Excel’s DATEDIF and TODAY function and typescript language with and without MomentJS library.

However, those methods require certain level of technical knowledge of using MS Excel and certain programming skills for typescript. Our how old calculator on the other hand, stands out for its user friendliness and brutal accuracy. you won’t find the combination anywhere else.

Our Birthday Calculator is ridiculously easy to use and quick. With that said, let’s now move and explore the actual process. All you have to do is follow the simple steps below to know “what is my age”.

  • Input the date of birth of a person or date of manufacture of an object with day of the month, month and year.
  • Then optionally (For higher accuracy) input the exact time of inception of an object or the time of a person’s birth.
  • And then press ‘Calculate’ and you’re done.

Following the above steps, you’d get the output in less than 3 seconds that would outline your age in years, months, days, hours, minutes and seconds. You can know how many years old you are, or how many months or hours or even minutes and seconds.


To give you an idea, consider that a person was born on 27th of November 1999 at 4:00 PM.

Putting these inputs and calculating the age, we get the age in days, months, years, and seconds.

Years 19 years 11 months 7 days

Months          239 months 7 days

Days   7281 Days

Hours 174751 Hours 32 Minutes 3 Seconds

Minutes         10485092 Minutes

Seconds         629105523 Seconds

So with age difference calculator you can easily calculate age from date of birth. It will also give you answer of the simple query “how old will I be” or “how many months old am I” or “how old was I” on this date.


Additional Features

The chronological age calculator has an additional advanced option which you can use to determine how old a person or an object would be at a particular date and time in the future given that the person’s date of birth or the object’s date of manufacture is provided for.

Staying true to its precision, the advanced option will calculate the age of the person or object at a given time in the future in the same fashion. This feature can be helpful to the students of mathematics in their assignments with such queries.
