How is age calculated?
The age calculator counts full years first, then full months, then the remaining days between your date of birth and the chosen date, correctly handling months with 28, 29, 30 or 31 days and leap years. This is the same method used on government, school and job application forms.
Age on a specific date (for exams and jobs)
Recruitment notifications and entrance exams often set an age limit “as on” a cut-off date, for example 1 January or 1 August. Change the Age on date field to that cut-off to check your eligibility in seconds. Always confirm the rules in the official notification, as relaxations may apply.
Fun facts about your age
Besides years, months and days, you will see your age in total months, weeks, days and hours, the weekday you were born and a countdown to your next birthday. Want to count days between any two dates? Try the date difference calculator.
