While you might know your age in years, knowing your exact age in days, minutes, or even seconds offers a unique perspective on your life's journey. Here are common reasons why people use our tool:
Our tool uses the Gregorian calendar, the most widely used calendar system in the world. It accounts for:
Did you know your age can be different depending on where you are in the world?
This is the most common system. You start at age 0 and turn 1 on your first birthday. Our calculator primarily uses this standard.
In this traditional system, you are 1 year old the moment you are born, and you gain a year on New Year's Day, not your birthday. This means you could be 1-2 years older in Korea!
Ever wondered about the numbers behind your life?
By age 30, your heart has likely beaten over 1.1 billion times.
An average 20-year-old has spent approximately 6-7 years just sleeping.
By age 18, you have taken roughly 150 million breaths.
This happens when your age matches the day of the month you were born (e.g., turning 25 on the 25th).
To calculate your age manually, subtract your birth year from the current year. If the current month is less than your birth month, subtract 1 from the result. For days, use the number of days in the previous months. It's complex to get right with leap years—our calculator handles this instantly!
Absolutely. This tool is perfect for parents wanting to know their baby's age in weeks or days, which is often tracked for developmental milestones (e.g., "12 weeks old").
The most accurate method is using the Date-Time difference. By including the specific time of birth, we can calculate your age down to the exact second, accounting for every leap year and time zone shift since you were born.
Currently, this page defaults to "today," but you can use our Date Difference Calculator to find out how old you will be on a specific future date like your graduation or retirement.
Chronological age is simply the time elapsed since birth. Biological age is a medical concept describing how fast your body is aging based on biomarkers. This calculator provides your precise chronological age.
