What is my age?

Age, in general, is the amount of time for which something existed.

A person's age is the time that has passed from the moment they were born. The time before birth is called the gestational age (age of a pregnancy is counted from conception).

In most parts of the world, a baby starts life at 0 and becomes 1 year old on the first anniversary of their birth. However, in some countries (notably in Korea) age is counted differently. In the text we'll use the most common system.

Let's see how to use the age calculator to help you answer the question - "what is my age?".

How many days/weeks/months/... old am I?

To check your age in different units, enter your date of birth, make sure you have today's date in the second field, and set the desired unit in the last field of the age calculator.
