Frequently asked questions
How does the age calculator work?
It compares your date of birth with today's date and counts the full years, then the remaining months, then the leftover days. It also totals every day between the two dates.
Does it account for leap years?
Yes. Because the total day count is based on the actual calendar dates, leap days are included automatically in the totals shown.
Why might my age look off by a day?
The calculation uses your device clock and local date. Around midnight, or if your time zone differs from where you were born, the day count can shift by one.
