Frequently Asked Questions
What is an Age Calculator?
An Age Calculator is a tool that determines your exact age based on your date of birth. It calculates the number of years, months, and days you have lived, and can often determine your age in days, hours, or even minutes.
How do I use the Age Calculator?
Simply enter your date of birth into the input field. You can optionally enter a specific date to calculate your age 'as of' that date (this defaults to today if left blank). Click the 'Calculate' button to see your age breakdown.
Does this account for leap years?
Yes, the calculator automatically accounts for leap years and the varying number of days in each month to provide an accurate age down to the specific day.
Can I calculate my age in the future?
Yes. If you enter a target date in the 'Calculate Age At' field that is later than today, the calculator will tell you how old you will be on that future date.
Why does the result show months and days?
Stating age in years only is an approximation. The calculator provides a precise breakdown (e.g., 20 years, 3 months, and 12 days) to give you an exact measurement of time elapsed since birth.
What timezone is used for the calculation?
The calculator typically uses the current date and time of the device or browser you are using to determine 'today's' date. Age is calculated based on calendar days rather than specific hours.
