## How to Calculate Age?

The Oxford dictionary defines “Age” as the length of time that a person has lived or a thing has existed. The method of calculating age involves the comparison of a person's date of birth with the date on which the age needs to be calculated. The date of birth is subtracted from the present date, which gives the age of the person. Age = Present date - Date of birth

Let us understand this with the help of the following example.

### Solved Example:

The date of birth of Ron is July 25, 1985 (25/07/1985). Find his age.

### Solution:

Using the formula to calculate Ron's age:

Age of a Person =  Present date - Date of birth

Ron's Date of Birth =  July 25, 1985

Present Date = January 28, 2021 (Taking this as the current date)

Subtract the numbers starting from the days, followed by months and then the year.

= (1st of January to 28th of January 2021) + (25th of July to 31st of December 1985)

= 35 year  + (28 days) + (6 + 31 + 30 + 31 + 30 + 31) days.

= 35 years + 28 days + 159 days

= 35 years + 187 days

= 35 years + 180 days + 7 days

= 35 years + (6 × 30) days + 7 days

= 35 years + 6 months + 7 days

= 35 years, 6 months, 7 days

Therefore, Ron's age is 35 years, 6 months, 7 days.

Now, try the calculator to find the age of the people with the following of births.
