What is the Age Calculator?
This age calculator works out your exact age from your date of birth – in years, months and days – and also shows your age in total months, weeks, days and hours. It tells you which day of the week you were born on, your zodiac sign and exactly how many days are left until your next birthday.
You can also change the second date to find someone’s age on a specific day, for example on an exam date, a job application deadline or the date a document was issued.
How to use the Age Calculator
- Pick your date of birth.
- Keep today as the second date, or choose any other date.
- Read your exact age and your next-birthday countdown instantly.
How is age calculated?
The calculator counts full years first, then the remaining full months, then the leftover days, using the real length of each month and leap years. For example, someone born on 15 January 2001 is 25 years, 8 months and 10 days old on 25 September 2026.
Where is an exact age needed?
- School admissions and age-limit checks for exams and government jobs.
- Visa, passport and insurance forms.
- Sports categories and competitions with age brackets.
- Planning birthdays and milestone celebrations.
Frequently asked questions
Does it handle leap years?
Yes. It uses the real calendar, so 29 February birthdays and leap years are counted correctly.
How do I calculate age for a job application?
Set the second date to the application’s closing date – many forms ask for age on that date, not today.
Why does my age in days look so big?
A 25-year-old has lived more than 9,000 days! The total counts every day since birth.
Is my birth date stored?
No. The calculation happens only in your browser.
This age calculator is 100% free, needs no signup and works on phones, tablets and computers. Your data is processed in your browser and never uploaded.
