How old am I? Enter your date of birth above and this free age calculator answers instantly — your exact age today in years, months, and days, plus your age in weeks, hours, seconds, and heartbeats. It accounts for leap years automatically, works on any device, and needs no sign-up.
You'll also see your generation, the day of the week you were born, a live countdown to your next birthday, and milestones like your 10,000th day and 1 billionth second alive. Your birth date is processed entirely in your browser and never stored.
WhatIsMyAge.me is a free, focused age calculator that tells you exactly how old you are — not just in years, but in months, days, hours, minutes, and seconds. Enter your date of birth and your complete age appears instantly, no account required.
Most age calculator sites are built around general-purpose calculator hubs, where your question is one of hundreds competing for space. This site exists for one reason only: to give you a precise, accurate age from a date of birth, as fast as possible.
Your exact chronological age in years, months, days, hours, minutes, and seconds. All units appear together in one result — no dropdowns, no page switching.
Anyone who needs a precise age — parents filling in school admission forms, professionals verifying dates for documents, healthcare workers checking patient ages, or simply curious people who want to know how many seconds they have been alive.
The calculator accounts for leap years, varying month lengths, and end-of-month date boundaries. A person born on February 29 is handled correctly.
Your date of birth is processed entirely within your browser. Nothing is transmitted to a server. Nothing is stored or linked to you. The calculation happens locally.
Age is rarely just a number in the contexts where it truly counts. Here are the situations where people reach for a precise age calculator most often.
Many schools and districts require children to meet an age cutoff to the day. Being one day short of the threshold can mean waiting another full year. Exact age calculation removes all guesswork.
Working holiday visas, dependent child entries, and many immigration categories require age in years and months on the date of application — not just a birth year.
Doctors, nurses, and pharmacists use exact age for dosing calculations, developmental assessments, vaccine schedules, and screening eligibility — often to the month or day.
Many competitive exams, government roles, and age-gated job categories have strict minimum and maximum age limits calculated as of a specific date. One day past the cutoff can mean disqualification.
How many days have you been alive? When will you turn exactly 1 billion seconds old? What day of the week were you born? These questions make for surprisingly memorable birthday moments.
Courts, solicitors, insurance providers, and pension administrators all work with completed age — the number of full years elapsed — calculated from your exact date of birth to a specific reference date.
Age calculation looks simple. Subtract your birth year from the current year and you get a number. But that rough figure is wrong roughly half the time — because it does not account for whether your birthday has passed yet this year, how many days are in each month, or how leap years affect the total day count.
A precise age calculation works differently. It computes the number of full years elapsed, then the remaining months, then the remaining days — accounting for every calendar edge case along the way.
Select your day, month, and year of birth using the date picker above. The full date is required for precise results — year alone is not enough.
By default, the calculator uses today's date. You can change this to any past or future date — useful for forms that ask for your age as of a specific deadline.
Your age appears in all units simultaneously — years, months, days, hours, minutes, and seconds — in a single result screen. No dropdowns. No extra pages.
Curious about your age in days, what generation you belong to, or when you'll hit one billion seconds? The blog below covers these and dozens more age-related questions.
Most people think of age in years. Here is what those years look like in other units.
Beyond your exact age, there is a lot more to discover. The WhatIsMyAge.me blog covers age curiosities, calculation guides, and tools for specific use cases.
WhatIsMyAge.me was created because most age calculator sites bury the tool under advertising, require you to navigate between multiple pages for different units, or deliver a result surrounded by so much surrounding content that finding the actual answer takes longer than it should.
This site does one thing: it tells you how old you are, precisely, in every unit that matters, immediately. The blog adds educational context for people who want to understand the calculation, explore what their age means in different units, or learn when a precise age calculation is legally or clinically important.
Every calculation uses the Gregorian calendar standard and handles all known edge cases — leap years, month-end dates, and year-end boundaries — correctly. If you notice a result that seems wrong, use the contact page to let us know.
