What is an Age Calculator?
An age calculator works out your exact age from your date of birth - not just the year count, but the precise years, months and days, plus fun totals like how many days and hours you have lived and how many days are left until your next birthday. Pick your birth date above, leave the second date as today (or change it), and press the button. Everything runs in your browser; when you are done, you might enjoy turning a birthday message into speech with our free text to speech generator.
How to Use the Age Calculator
- Enter the date of birth. Use the first date box. If you are checking for someone else - a child, a parent - enter their birth date instead.
- Check the second date. It is already set to today. For a form that asks for age as on a specific date, change it to that date.
- Press Calculate My Age. You will see the exact age in years, months and days, the total months, weeks, days and hours lived, the weekday of the birth, the zodiac sign, and a countdown to the next birthday.
How the Calculation Works
The calculator uses the same method a careful person uses on paper. It counts full years first, then full months, then the leftover days. If the leftover days come out negative, it borrows the real number of days from the previous month - 31 from January, 28 or 29 from February - which is why two people born in the same year can show slightly different month and day counts. Total days are counted on the real calendar, so every leap day (29 February) you have lived through is included. That is why the totals here can differ by a few days from a rough years-times-365 estimate.
Where an Exact Age Matters
Most of the time, knowing you are 24 is enough. But some moments count age to the day. School admissions often require a child to be a certain age on a cutoff date like 31 March or 30 September. Government job and exam forms set minimum and maximum ages as on the application date - being a few days over the limit can close the door, so it is worth checking before you apply. Retirement and pension planning, insurance policies and sports age-group categories work the same way. Set the second date above to the date that matters, and you will know exactly where you stand.
