When exact age matters
Most of the time "I am 29" is enough, but government exams, school admissions, visa forms and insurance policies often need age down to the day, calculated on a specific cutoff date. Getting it wrong by a single day can make an application invalid. This tool does the calendar math for you, correctly handling leap years and months of different lengths.
Frequently asked questions
How is exact age calculated?
The calculator counts full years from your birth date to today, then full months after your last birthday, then the remaining days. This matches how age is stated on official forms.
Why do forms ask for age as on a specific date?
Exam and job applications often set a cutoff date, for example age as on 1 January. Change the second date in this calculator to that cutoff to get the exact figure the form needs.
How many days old am I?
Enter your date of birth and the calculator shows your total days lived alongside your age in years, months and days.
