What is the correct way to calculate age?

There are several ways to calculate age; the correct method depends on your information and what you want to use the age for.

For example, if you know the person’s date of birth and today’s date, you can subtract their birth year from the current year to get their age.

If you need a more precise age estimate, you can use the person’s date of birth and death (if known) or the person’s date of birth and a life expectancy table.

Remember that these methods will only give you an estimate of age, and the actual age may differ.
