Why developed Age Calculator?

Age is a very important part of our life. Also, it's used in many places. Generally, we are using it in identity proof certificates. Such as Passport, Driving License, Library Card, etc.

So, when we apply for a passport or driving license then there is always a blank field that asks us to enter our age. Sometimes we need to enter our exact age(in years, months, and days) on the form. So, it's very hard to figure it out manually. That's why we created an Age Calculator or Birthday Calculator to know your exact age online.

It's a great tool that lets you know how old you are. Also, it's completely free to use with a super simple process. Moreover, you can use this tool to find ages for different dates too. So, use this free app and determine your exact age quickly.

How to Calculate Age?

Most importantly, the age calculator takes two inputs from users.

  1. Birth Date
  2. Today's Date

So, to calculate age manually, we have to subtract today's date with birth date. As a result, we get duration between two dates and that's your "Age".

Let's take some examples to understand it deeply. Also, in the example, we will calculate only the years, months, and days.

Example 1:

Suppose Jason's date of birth is 05 January, 1990. Today's date is 10 September, 2019. Find out how old Jason is?

Example 1

So, Jason is 29 years, 8 months, and 5 days old.

Now the question arises, what if today's date of month is smaller than DOB's month?

So, let's take one example for that type of case.

Example 2:

Find the age for:

  • DOB = 10 August, 1994
  • Today's Date = 24 March, 2020
Example 2

As you can see above, 03 is less than 08.

So, in this case we will take 1 year = 12 months from 2020 and add it to 03 months.

Now, months will be 03 + 12 = 15 and year will be 2020 - 1 = 2019.

After subtraction, we get 25 years, 7 months, and 14 days.

What if today's date of month and day both are smaller than DOB's month and day?

You will get this question's answer in next example.

Example 3:

Let's take

  • DOB = 15 May, 1985
  • Today's Date = 05 February, 2018
Example 3

In this case, Month 02 is less than 05 and Day 05 is less than 15.

So, firstly, we will take 1 year = 12 months from 2018 and add it to 02 months.

As a result, Months = 02 + 12 = 14, and Year = 2018 - 1 = 2017.

After that, we will take 1 month = 31 days from 14 months and add it to 05 days.

Therefore, Days = 05 + 31 = 36, and Months = 14 - 1 = 13.

Finally, Age = 32 years, 08 months, and 21 days.
