Age Calculator

When this calculator is useful

An exact age is needed far more often than people realise, and an approximate one rarely suffices. Use this tool whenever a precise figure matters — completing an official form, checking that a young person has reached a legal threshold, confirming someone is over 18 for a contract, or working out exactly how many days old a newborn is for a clinic appointment. Because it returns years, months and days together, it answers questions that a single age number simply cannot.

It is just as good for everyday curiosity: discovering which day of the week you were born, settling who is the elder by how many days, or counting down to a landmark birthday. Enter the date in DD/MM/YYYY order as written across most of the euro area, and the calculator handles the calendar arithmetic — every leap year included — so you do not have to work it out by hand.

Understanding your result

The headline figure is your age in completed years, months and days. Read it as an exact interval rather than a rounded one: '34 years, 5 months and 2 days' means you have passed your 34th birthday and have been counting since. The years figure follows the standard Western convention of rounding down — you are 34 from your 34th birthday until the day before you turn 35.

You also see your total days alive, the weekday you were born on, and the time remaining until your next birthday. The days-alive count rises by one each day; only the years figure jumps, and it jumps on your birthday. If the number ever appears to skip, it is the years rolling over that drew your eye, not a break in the daily count.

A worked example

Imagine your date of birth is 15/01/1990 and today is 08/06/2026. The calculator returns 36 years, 4 months and 24 days: a full 36 years to 15/01/2026, then four whole months to 15/05/2026, then the remaining days to today. Your total days alive would be a little over 13,200, and 15 January 1990 fell on a Monday. Your next birthday, 15/01/2027, is around seven months away — handy when planning a celebration or organising a gift.

Points to be careful about

Most age-calculation mistakes come down to how the date is entered or to misreading what the figure represents.

• Typing the date in US MM/DD order by mistake — across most of the euro area the day comes first, so 03/04/1990 is 3 April, not 4 March.
• Expecting age in months to equal years times twelve; calendar months vary in length, so the months-and-days breakdown will not divide evenly.
• Forgetting that the years figure rounds down — you are not '35' until the actual day you turn 35, however close your birthday is.
• Assuming a 29 February birthday rolls over on a fixed date; the legal convention differs between member states, and this tool shows 28 February in non-leap years.

Euro-area legal-age and pension notes

Across the euro area, legal-age thresholds are broadly similar but not identical from one member state to the next. Eighteen is the age of majority and the usual voting age in most countries, though a few lower the voting age (Austria allows 16), and the drinking age ranges from 16 for beer and wine in some states such as Germany and Belgium to 18 elsewhere. This calculator only reports your exact age and applies none of these national rules, but the precise day count is exactly what you need when a threshold falls near a deadline.

Retirement ages also vary widely. Most member states set a statutory pension age between 65 and 67, and several — France, Italy, Germany and Spain among them — have recently raised theirs or scheduled increases. Use your exact age here as a starting point, then check your national social-security authority for the schedule tied to your birth year, since neither the retirement age nor the rules around early retirement are harmonised across the euro area.
