About Use of Calculators

Find out how old a person, location, or thing is. Calculator can also be used to calculate the interval between two dates.

The age calculator determines the age range in years, months, and days as well as in total days.

How to Determine Age?

This age calculator determines age using two approaches that are similar yet slightly different. The alternative approach is only used to compute age very precisely in total days.

Months are the same as weeks. Parents wouldn't say their child is 7 months old if she is actually 4 months, 31 days long, plus 2 months, 30 days long, and 1 month, 28 days long. Typically, we make generalisations about months of various durations and count them all as general months.

The age calculator determines age by treating all years and months equally and using language that is universally understood. However, the calculator employs a formula to determine the precise number of days between dates when computing days.

The age calculator makes use of a function that counts the number of leap years in a given amount of time. It determines the precise number of days in a partial year as well.

Format dates

You can enter months and days with a single digit in the age calculator. You are not need to add a leading zero to them. However, you must enter the 4-digit year.

In the US, dates can be formatted with a forward slash, a period, or a dash:

mm.dd.yyyy.
mm-dd-yyyy

When formatting dates in Europe, you can use a forward slash, a period, or a dash:

dd/mm/yyyy
dd.mm.yyyy

How Does a Calculator for Age Work?

The chronological age calculator employs cutting-edge algorithms to assist users in determining the age between given time intervals. The dob age calculator is a tool that delivers outcomes very quickly. Using this programme, I was able to determine a building's age, and the findings came in just a few seconds.

You'll immediately understand how it operates by counting the number of years, months, and days that have passed since the beginning to the present day. Every time period, including leap years and 31-day months, is calculated. As a result, you can anticipate an accurate computation based on the information you provided.

how to calculate age – If you also want to calculate your age or age but do not know how to calculate it, then this post of ours is for you.

In today's post, I will tell you in detail through 4 examples that you can calculate your age from your date of birth. Friends, this is just a calculation of addition and subtraction.

Once you understand this well, you can easily calculate the age of any person easily.

How to calculate age?

Two dates are required to extract Age, one is today's date and the other is Date Of Birth. You can find out your current age by subtracting your date of birth from today's date.

-: That is, the formula for extracting age is: -

Today's Date - Date of Birth

To solve it

You have to subtract the day of your date of birth from the day of today's date.
You need to subtract the month of your date of birth from the month of today's date.
You have to subtract the year of your date of birth from the year of today's date.

I will show you how to calculate through some examples so keep reading the post till the end.

There are three units in a date:

Day
Month
Year

Whenever you go to calculate the age, you have to calculate through these 3 units.

By arranging the day, month and year, we get –

day < month < year

That is, day is the smallest unit, month is bigger than that and year is bigger than that.

Also you should know –

30 days = 1 month
12 months = 1 year

In the examples that I will show you to make you understand, I will calculate on this date of birth (14-07-1995).

I will show you four types of cases. If you understand these four types of problems very well, then you can calculate the age of any person on any given day.

Case – 1

Suppose today's date is 23-12-2022 and your date of birth is 14-07-1995. As I said above. Now you have to calculate your age. Let's see how you can do it.

Problem

	Day	Month	Year
today's date	23	12	2022
date of birth	14	07	1995
Age	?	?	?

In such a situation, you can do this calculation very easily without any difficulty. Above I had told you the formula for extracting age –

Today's Date - Date of Birth

Day count

First of all we will subtract the day of birth date from the day i of today's date. 23 – 14 = 9 days

Month count

Subtract the month of birth from the month of today's date. 12 – 07 = 5 months

Count of years

Subtract the year of birth from the year of today's date. 2022 – 1995 = 27 years

Solution

	Day	Month	Year
today's date	23	12	2022
date of birth	14	07	1995
Age	9 days	5 months	27 years

Means your age as on 23-12-2022 is 27 years 5 months 9 days.

Case-2

Suppose today's date is 10-12-2022 and your date of birth is 14-07-1995. Now you have to calculate your age according to this date. Let's see how you can do it.

problem

	Day	Month	Year
today's date	10	12	2022
date of birth	14	07	1995
Age	?	?	?

In such a situation, your problem will not be solved easily. Its calculation has to be done in a different way. That formula to extract age will remain the same –

Today's Date - Date of Birth

Day count

When we go to subtract the day of birth from the day of today's date, we can see that the day of today's date is less than the day of birth. We know that a larger number cannot be subtracted from a smaller number.

So we'll borrow one month from today's date for the day. Now we know that a month is equal to 30 days. So the calculation of the day will be something like this. (10 + 30) – 14 = 26 days

Month count

Now that we have taken a month, first we will subtract one month from the month of today's date and then subtract the month of the date of birth from it. So the calculation of the month will be something like this. (12 – 1) – 07 = 4 months

Count of years

Subtract the year of birth from the year of today's date. 2022 – 1995 = 27 years

Solutions

	Day	Month	Year
today's date	(10 + 30)	(12 – 1)	2022
date of birth	14	07	1995
Age	26 days	4 months	27 years

Means your age as on 10-12-2022 is 27 years 4 months 26 days.

Case – 3

Suppose today's date is 22-01-2023 and your date of birth is 14-07-1995. Now you have to calculate your age according to this date. Let's see how you can do it.

Problem

	Day	Month	Year
today's date	22	01	2023
date of birth	14	07	1995
Age	?	?	?

In such a situation, your problem will not be solved easily. Its calculation has to be done in a different way. That formula to extract age will remain the same –

Today's Date - Date of Birth

Day count

First of all we will subtract the day of birth date from the day i of today's date. 22 – 14 = 8 days

Month count

When we go to subtract the day of birth month from the month of today's date, we can see that the month of today's date is smaller than the month of birth date.

We know that a larger number cannot be subtracted from a smaller number. So we'll borrow a year from today's year for the month. Now we know that one year is equal to 12 months.

So the calculation of the month will be something like this. (01 + 12) – 07 = 6 months

Count of years

Now that we have borrowed one year, first we will subtract one year from the year of today's date and then subtract the year of the date of birth from it. So the calculation of the year will be something like this. (2023 – 1) – 1995 = 27 years

Solutions

	Day	Month	Year
today's date	22	(1 + 12)	(2023 – 1)
date of birth	14	07	1995
Age	8 days	6 months	27 years

Means your age as on 10-12-2022 is 27 years 4 months 26 days.

Case – 4

Suppose today's date is 08-05-2023 and your date of birth is 14-07-1995. Now you have to calculate your age according to this date. Let's see how you can do it.

Problem

	Day	Month	Year
today's date	08	05	2023
date of birth	14	07	1995
Age	?	?	?

In such a situation, your problem will not be solved easily. Its calculation has to be done in a different way. That formula to extract age will remain the same –

Today's Date - Date of Birth

Day count

So we will borrow for one month from today's date. Now we know that a month is equal to 30 days. So the calculation of the day will be something like this. (08 + 30) – 14 = 24 days

Month count

Now that we have taken a month, first we will subtract one month from the month of today's date and then subtract the month of the date of birth from it.

But after that when we go to subtract the day of birth month from the month of today's date, we can see that the month of today's date is less than the month of birth date.

We know that a larger number cannot be subtracted from a smaller number. So we'll borrow a year from today's year for the month. Now we know that one year is equal to 12 months.

So the calculation of the month will be something like this. (5 – 1 + 12) – 07 = 9 months

Count of years

Solutions

	Day	Month	Year
today's date	(8 + 30)	(5 – 1 + 12)	(2023 – 1)
date of birth	14	07	1995
Age	24 days	9 months	27 years

Means your age as on 10-12-2022 is 27 years 9 months 24 days.
