Age calculator
Give it a date of birth and it returns an exact age split into years, months and days, alongside the total days lived and a countdown to the next birthday. People reach for it when a form demands an age in a precise format, when checking eligibility for a pension, licence or membership, or just to satisfy curiosity about a milestone. You can measure age as of today or pin it to any other date, which is handy for working out how old someone will be on a future event.
How it works
- Type in the date of birth.
- Leave the second date empty to measure against today, or set a specific date to find the age on that day.
- The answer counts complete years first, then the remaining months, then the leftover days.
- Alongside that breakdown it shows the running total in plain days and in weeks, plus the days left until the next birthday.
age = whole years, then leftover months, then leftover days
The calculator subtracts the birth date from the target date one unit at a time. It counts the complete calendar years that have passed, then the whole months since the last birthday, then the days since the last month boundary. When a day or month has not fully elapsed it borrows from the unit above, exactly as a clerk would when filling in a form by hand.
- Y
- complete years elapsed since birth
- M
- whole months after the last full year
- D
- remaining days after the last full month

Worked example
Born on 1 January 2000, measured on 1 June 2026: that is 26 years, 5 months and 0 days. The tool also reports the cumulative days lived, the same figure in weeks, and that the next birthday falls 7 months out.
Key facts
- A year of life is on average 365.25 days, which is why a precise count needs real calendar dates rather than a flat multiplier.
- Someone born on 29 February has a true birthday only once every four years, though their day count keeps ticking the same as anyone else.
- Two people born minutes apart on either side of midnight can show a one-day difference in total days lived.
- The next-birthday countdown shortens by one each day and resets to roughly 365 the morning after the birthday.
Tips
- For an age on a passport or visa form, set the second date to the exact day the form is assessed, not today, so the figure matches.
- To find an age at a future event such as a wedding, put the event date in the second field and read the years and months back.
- If you only need whole years, ignore the months and days and read the first number; forms that ask for completed age want exactly that.
- Double-check the day and month order when typing a date of birth, since a 03/04 and 04/03 mix-up shifts the result by weeks.
Frequently asked questions
How are the months and days figured out?+
It takes the whole years first, then counts the extra months, then the remaining days, borrowing from the previous month where a month has not fully elapsed. This matches how most official forms expect an age to be written.
Are leap years handled?+
Yes. Every count works from real calendar dates, so 29 February, varying month lengths and leap years are all accounted for automatically.
Can I find an age for a future date?+
Yes. Set the second date to any day, past or future, and the result is the age as of that day rather than today.
How is someone born on 29 February treated?+
Their day count is exact regardless. In common years the calculator rolls the anniversary to the nearest valid date when displaying months and days.
