### What is Age?

Age is calculated by the number of years an individual has been alive.

The term "chronological age" refers to the number of years someone has lived. Chronological age is different than biological age, which is based on how old an individual's cells look under a microscope. The two types of ages are used for different purposes, such as when determining when to start school or how much an insurance company should charge for life insurance.

### How To Calculate Your Age in Hours and Minutes

1. Calculate the number of years that have elapsed since a given date (your birth date) by subtracting the current day from that date.

2. Multiply this number by 365, which is the total days that have elapsed in those years.

3. Multiply this number by 24 to get the number of hours spent on earth since birth.

4. Multiply those hours by 60 to get how many minutes you have been alive on earth since birth.

### What is an Age Calculator and Why do People Use Them

An age calculator is a website that calculates one's age. People use it to find out their present-day age in relation to past years.

For some age calculators, one doesn't need to know their birth date before using an age calculator. All they need are the days, months, or years since their birth, which can be tracked by looking at their calendars. They can also use the date of another person's birthday which they are sure about to calculate that personâ€™s age without knowing his/her birthdate.

The use of an age calculator is beneficial because it shows how many days, months, or years have passed since someone's birthday and how old he or she currently is in relation to the past year(s).
