Frequently asked questions
How do I calculate my exact age?
Subtract your date of birth from today's date, borrowing months and days as needed. This calculator does it instantly and also shows total months, weeks, days and hours lived.
How many days old am I?
Enter your birth date above — the calculator shows your total days lived alongside your age in years, months and days.
Does it account for leap years?
Yes. Ages are computed with real calendar dates, so leap days (like Feb 29) are handled correctly.
How old will I be in 2030?
Enter your birth date and set "Calculate age as of" to any date in 2030 — the calculator works for past and future dates.
What day of the week was I born?
The calculator shows this automatically under "Born on a" — a fun detail for birthday trivia.
Why do some age calculators give different results?
Most differences come from whether the current day counts as "complete". This calculator counts full elapsed years, months and days from your birth date, the standard chronological method.
