Age Calculator

An online age calculator is a digital application available on the Internet. There are several different types of age calculators freely available online. However, people mostly prefer using an age calculator online by date of birth to calculate a person’s age quickly. In addition, a complex digital age calculator tool can also determine the age of significant historical places from the day they were first constructed.

The age calculator evaluates their age based on their given birth date from an individual’s perspective. The calculator inputs the date of birth in a specific format and outputs the individual’s age in years, months and days. Advanced calculators further drill down the results into weeks, hours, minutes, and seconds.

In olden times, different cultures monitored the rotation of celestial objects like the Sun and the moon to calculate how old a person was. These methods were adequate but not accurate. Later on, with the help of Gregorian and Lunar calendars, people started calculating their age based on the days that evolved from their birthdays. The same concept is now implemented in an online age calculator.

How does an age calculator work?

The process of computing the age of a person is relatively simple. The application subtracts your date of birth from the current date or any other date of your choice in the future. As a rule, the date of birth and the current date follow a specific format to provide correct results. Invalid dates or values before your date of birth are not allowed. Let us now understand how to calculate age using an online age calculator. 

The application is designed to calculate your current age by taking in your date of birth as input. The tool then subtracts the date of birth from the present date value or any other provided data. The application uses the Gregorian calendar as a reference for calculations. People first used it in 1582. It divides the year into 365 days and 366 days in case of a leap year. The age calculator considers an individual’s age starting from and increasing each year after the passing of twelve months. These calculators also consider the user’s time zone and output the results accordingly.

Below is an overview of the operation of an age calculator:

  • Provide your date of birth in the input field. It generally accepts values in DDMMYYYY format.

  • Next, fill the current date field with the relevant date of your choice for which you wish to calculate your age. 

  • Click on the SUBMIT button to calculate the age and check the results. From the results, you can verify your age, which is usually displayed in a format of years, months, and days.

  • For proceeding with more calculations, you can clear the present values and re-enter new values of your choice. It is advisable not to enter invalid data formats.

For example, let us consider the below scenario to understand the working of an age calculator better.

Scenario: A person’s date of birth is October 25, 1985 (25/10/1985 in DDMMYYYY format). What will be his age as of January 28, 2022? 

Using the above-given steps:

Date of Birth = October 25, 1985, or 25/10/1985

Given date = January 28, 2022, or 28/01/2022

Total difference in years = 2021 – 1985 = 36 years.

Total remaining months from October 25, 2021 to January 25, 2022 = 4 months.

Total remaining days from January 25, 2022 to January 28, 2022 = 3 days.

Therefore, the person’s present age is 36 years, 4 months, and 3 days.

Conclusion

The process of an online age calculator is relatively quick and straightforward to evaluate a person’s age. Knowing the exact age of a person is exciting information for understanding issues related to health disorders. In addition, online tools have numerous practical uses, like measuring your blood pressure by age calculator.
