Calculate your exact age in years, months, days, hours and seconds. Gregorian and Hijri calendars, with a live countdown to your next birthday.
Pick your date of birth to see your exact age.
Enter your date of birth by day, month, and year and instantly get your exact age broken down into full years, remaining months, and remaining days. The calculator handles leap years automatically so the result stays accurate whether the current year is 365 or 366 days long.
Beyond years and months, the tool converts your entire lifetime into total days, weeks, hours, minutes, and seconds. It is a quick way to check how many days you have lived and how many days remain until your next birthday.
Need to compare the age of two people? Calculate each birth date separately and subtract the totals in years, months, and days. The same method works for finding the age gap between siblings, spouses, or classmates.
Every calculation runs fully in your browser — no data is sent to a server. Once the page has loaded once, the age calculator keeps working even if your internet connection drops, so you can use it anywhere.

Free online age calculator — the fastest way to answer "how old am I exactly?" in seconds. Pick your date of birth from the day / month / year dropdowns in either the Gregorian or the Hijri (Umm al-Qura) calendar, and the tool instantly returns your precise age in complete years, months and days, plus the same age expressed in total months, weeks, days, hours, minutes and seconds. It also converts your date of birth between the Hijri and Gregorian calendars, shows the name of the birth month in both systems (Muharram, Safar, Rabi al-Awwal… / January, February, March…), tells you the day of the week you were born on and the season of your birth, and counts down the exact time remaining until your next birthday in months, days, hours and minutes, along with the weekday and full date it will fall on. A life-stages timeline lists your age year by year with the corresponding stage (infancy, childhood, adolescence, adulthood, middle age, old age), so you can see where you stand today and where you'll be in the years ahead — useful for retirement planning, school milestones or tracking a child's growth month by month. A fun-facts panel estimates how many times you have breathed, how many times your heart has beaten, how much time you have spent sleeping and how many hours you have spent eating over your entire life, based on standard daily rates for a healthy human body multiplied by the number of days you have lived. This age calculator is ideal for official forms that require an exact age, birthday cards, ID / passport applications, insurance forms, school and university enrollment, medical records, and anyone who simply wants to know their age in the Hijri calendar as well as the Gregorian one. Every calculation runs entirely in your browser — your date of birth is never uploaded or stored on any server.
Fill in the input fields — the age calculator accepts numbers, dates, or units depending on the mode.
Pick the operation or unit you want (add, subtract, percentage, convert) using the toggles above the inputs.
The answer updates instantly as you type; no need to click a "calculate" button.
Copy the result to your clipboard or take a screenshot for reports, invoices, or homework.
Doing this calculation by hand every time is a waste of your attention. Age Calculator keeps the math boring and correct so you can focus on the decision it feeds into. The formulas are transparent, the inputs are forgiving, and every result is deterministic — the same inputs always produce the same answer, which matters when you need to defend a number to a client or a manager. Toolzer's design philosophy is simple: privacy-first (no tracking, no accounts), performance-first (the page is interactive in under a second on a 3G connection), and honesty-first (no fake ratings, no dark patterns, no upsells). Age Calculator follows the same rules as every other utility on the site. You can bookmark this page, share the URL with a colleague, or pin it to your browser's toolbar — the experience will be identical every visit, and it will keep working even if you're on airplane Wi-Fi. Real people use this tool for real work — freelancers cleaning up client deliverables, sysadmins triaging tickets, students finishing assignments — and it is tuned for those workflows, not for demo videos.
We compute the difference between your date of birth and today's date in complete years, then adjust for the remaining months and days, so the result matches the legal, medical and administrative definition of age (completed years, months and days).
Yes. You can enter your date of birth as either Gregorian or Hijri using the day / month / year dropdowns. The tool converts between the two calendars using the standard Umm al-Qura tables and always shows both your Gregorian and your Hijri age in years, months and days, along with the Hijri month name.
The Hijri (lunar) year is about 11 days shorter than the Gregorian (solar) year, so every 33 Gregorian years you gain roughly one extra Hijri year. The gap grows with age, which is why the tool always displays both ages side by side.
As a live breakdown of the months, days, hours and minutes remaining until your next birthday, together with the exact weekday and date it will fall on, based on your local time zone.
Yes. As soon as you enter your date of birth, the tool tells you whether you were born on a Sunday, Monday, Tuesday, Wednesday, Thursday, Friday or Saturday, and in which season (spring, summer, autumn or winter).
They are estimates. We take the standard average daily rates for a healthy human body — heartbeats per minute, breaths per minute, recommended sleep hours, etc. — and multiply them by the number of days you have lived to give an approximate lifetime total.
Yes. The tool works from a few days after birth up to any age, so you can precisely track a baby or child's age in years, months and days for medical appointments, vaccinations, school enrollment and developmental milestones.
Leap years are handled correctly. People born on 29 February are considered one year older starting from 28 February in non-leap years.
No. Everything runs locally in your browser; your date of birth is never uploaded, stored or shared.
The Gregorian calendar is solar (365 or 366 days per year), while the Hijri calendar is lunar (354 or 355 days per year) — about 11 days shorter. Your Hijri age therefore comes out slightly higher than your Gregorian age, and the gap grows by roughly one full year every 33 Gregorian years. The calculator displays both ages side by side so you can quote the correct figure on any official form.
Enter the earlier date as the date of birth and the tool automatically computes the interval to today in complete years, months and days. To compare the age of two people, calculate each person's age separately and subtract the results to get the exact age difference between two people or two dates.
The calculator converts the interval between your date of birth and today's date into the total number of completed days, accounting for leap years. It also shows your age in weeks, hours, minutes and seconds — handy for medical forms, insurance paperwork and long-term project planning.
