Frequently Asked Questions
How does the age calculator work?
Enter your birth date, and we calculate your exact age down to the second. We show: years, months, days, total hours, total minutes, and total seconds lived. We also tell you the day of the week you were born and your next birthday countdown.
What's the difference between chronological age and calendar age?
Chronological age is your exact age based on birth date (what we calculate). Calendar age is how old you appear or function. Some cultures also count 'nominal age' (counting the year you're born as age 1, common in Korea).
Can I calculate the age difference between two people?
Yes! Enter two birth dates, and we'll show the exact age difference in years, months, and days. Perfect for comparing ages with siblings, friends, or partners.
