Frequently asked questions
Common questions about the Age Calculator.
How is my exact age calculated?
It counts the full years, months and days from your date of birth to today (or a target date you choose), and can also break it down into hours and minutes.
Does it account for leap years?
Yes. The day-by-day calculation correctly handles leap years and the differing lengths of each month, so the result is accurate rather than an approximation.
Can I calculate age on a future or past date instead of today?
Yes — set a target date and it will tell you how old you will be (or were) on that day, which is handy for eligibility cut-offs and milestones.
Why does the number of days look different from just subtracting the years?
Because months have different lengths and leap years add a day, your age in total days is not simply years times 365. The tool counts the actual calendar days between the two dates.
Can I use it to find days until a birthday or anniversary?
Yes. Choose a future date and it shows the precise time remaining down to days, hours and minutes.
