Calculate exact age in years, months, and days from any date of birth, plus total days lived, the day of the week you were born, and days until your next birthday.
An age calculator precisely determines how old a person is based on their date of birth and the current date. Beyond the basic years-months-days breakdown, this calculator also shows the day of the week you were born, the total number of days you have been alive, how many hours and minutes that represents, and how many days remain until your next birthday. It is useful for checking age eligibility for travel visas, employment, driving licenses, pensions, and age-restricted events, as well as for celebrating milestones like a child's 1,000th day or an adult's 20,000th day of life.
Formula
Years / Months / Days = calendar-aware difference between DOB and today. Total Days = absolute millisecond difference ÷ 86,400,000.You usually need an age calculator at the most inconvenient moments — filling out a visa form at midnight, double-checking whether a cousin is old enough for the family Umrah package, or settling a sibling argument about who is exactly how many days older. The bit most people get wrong is doing the math in their head: subtract the years, ignore the months, hope nobody notices. Then a passport office clerk catches it. Punch the date of birth in here and you get years, months, days, the weekday you were born, and the total days you have been alive — the last one is fun in a slightly humbling way, because seeing that you have lived 11,000 days makes the next 5,000 feel suddenly precious. Pro tip: when you fill any Pakistani government form, always calculate age 'as of the closing date of the application', not today — embassies and FPSC routinely reject forms where someone was 17 years 11 months on the cutoff. And if you were born in Pakistan but live in the Gulf, remember your CNIC age and your residence-visa age can lag by a day either side of midnight Karachi time, depending on where you were when the date flipped.

Age calculation is calendar-aware, which means month boundaries are respected: from January 31 to February 28 is counted as 28 days, not 31 days, because February genuinely has only 28 days (or 29 in a leap year). The total-days figure is a pure timestamp subtraction and automatically accounts for leap days along the way. Years are incremented only after the same month-day in the target year has fully passed — a person born on March 5, 2000 becomes exactly 25 on March 5, 2025, not a day earlier.
