How do you calculate chronological age?


Chronological age is how long a person or thing has existed. For a person, this is based on that person's birthdate, compared to the current date (date used for the calculation. You need to include at least the month, date, and year in your calculation. A rough example of this is someone's birthdate is June 20, 1950. If today is June 10, 2010, then you would subtract the birth year from the current year, to get 60 years. Now, since this person's birthday has not yet occurred in the calculation year, you adjust the age by the number of days till the birthday (assuming a year is 365 days). So, this person is 59 years and 356 days.
