“How old are you?” is easy. “How old are you in years, months and days on a specific date?” is harder, especially when forms, visas, exams or job applications have strict age limits. An age calculator gives you the exact answer in seconds.
When you need your exact age
- Checking eligibility for exams, jobs or scholarships with an age cut-off date.
- Filling in visa, passport and insurance forms.
- Working out a child’s age in months for school admission or health records.
- Fun facts: how many days you have been alive.
How to use the Age Calculator
- Open the Age Calculator.
- Enter your date of birth.
- See your age in years, months and days, the total days you have lived, and the days left until your next birthday.

Why manual calculation goes wrong
Months have different lengths (28, 29, 30 or 31 days) and leap years add an extra day. Counting by hand, it is easy to be off by a day or a month, which can matter when you are close to an official age limit.
Calculating age on a specific date
Many applications ask for your age “as of” a particular date, such as 1 January or the closing date of an application. Always read the exact wording, because being one day short of an age limit can affect eligibility.
Fun facts to try
- You reach 10,000 days old at roughly 27 years and 4 months.
- People born on 29 February celebrate their exact birthday only in leap years.
