Chronological Age Overview
The concept of age in each country is very different. Some places believe that any newborn baby is one year old at birth time.
In contrast, other areas in most western countries begin to calculate a person's age from when one was born, which is closely linked to an individual's traditional culture, values, and accumulated knowledge.
The specific date of the birth calculator allows you or any creature, such as a tree, building, animal, or person, to calculate the required and chronological order. It usually displays each person's date of birth in European or American style.
So what is chronological age? Are there any effective time formulas that determine the exact age? The following content is all you need to answer these questions:
Chronological ages overview
It is a parameter representing the total amount of time you have lived from birth to modern times. Its general principle is based on determining the years, months, days, hours, and minutes spent in each person's life. On the other hand, it also refers to a definite period for you to count your days most accurately.
The truth is that the aging rate varies from person to person. Some people age very quickly, while others slow down. Hence, when you come across someone, you think they seem younger or older than they are.
Many studies have shown that starting date is unreliable and does not fully reflect the human age. Many factors affect the aging process beyond our control, such as genetics, diet, and lifestyle habits.
The formula of chronological age
All that is in the formula for calculating an age for a day, month, and year. Here is a concrete example to help you better understand this formula.
Date of birth  Current day, month, year  Chronological age 
21  12  01 
08  11  02 
1996  2022  26 
For detailed explanation:

To calculate the date, add the current date and the birth date, then borrow 30 days from the following months. Specifically: 21 + 12 = 33 and 33  31 = 1 day

The number of months will be the subtraction's result: 10  8 = 2 months.

Subtract the current year from the birth year to get the final result: 2022  1996 = 26 years.
Thus, the exact age calculated by age is 26 years, 02 months, and 01 day.
How To Calculate My Birthdate?
As mentioned, age calculation is different in some cultures and countries. Many places calculate age or birth date by counting years with or without the current year. For example, even though it's their 21st year now, they're only in their 20s by convention.
In China, everyone assumes they are one year old from birth and add a year on the traditional New Year's day. Simply put, a baby will turn one year old on New Year's Day even though he was only born four days ago.
Calculating the birth date is a complex task. It is very complicated and confusing at different times in a month. Specifically, in the same month, you will be older than the person born after you.
Let's dive into the birthday calculation examples with the current day, month, year of birth, and age data.
Example 1: How to calculate the birthday of a person who is 32 years old and 12 days on 11/12/2022 (for the current date)?
Implementation steps:

Calculate the year: The result of the calculation "2022  32 = 1990" is the years you need to find.

Calculating age days and months: Subtract 12 days from 11/12/1990, and we get the result: 1/11/1990
So this person's birthday is 11/1/1990
Example 2: On January 8, 2021, a person's age is 27 years, two months, and one day. So, when was he born?
Implementation steps:

Calculate the year: Similar to the example above, you must subtract 2021 from 27 to get the result "1993".

Calculating days and months: Continue subtracting two months and one day from January 8, 1993. And we have 7/11 as the final result.
Thus, this person was born on November 7, 1993.
How to calculate the upcoming birthday?
Calculating upcoming birthdays is quite simple as long as you have a solid foundation for estimating age. Specifically, you subtract the age of the current year from the birth year and then count the days until your next birthday.
For example, if you were 20 years and four months old on May 3, 2020, your next birthday will be on January 3, 2021, 9 months later.
The calculation is as follows:

Take the current year, 2020, minus the age of 20; we get the result 2000.

Continue to take 5  4, and we have the number of months as 1

Accordingly, you know that you were born on January 3, 2000, and your next birthday will be January 3, 2021. You will need to wait another nine months to celebrate your next birthday.
