About this tool
Useful for exam and job age limits, which are usually counted on a fixed cut-off date. Change the 'age on' date to check eligibility for any date.
Getting an exact age for forms and plans
Working out age sounds trivial until you need it exactly. Application forms, school admissions, insurance proposals, exam eligibility and pension paperwork often ask for age in years, months and days on a specific date, not just today. Counting by hand is easy to get wrong because months have different lengths and leap years add an extra day every so often. This calculator handles those details for you.
The most useful feature is the option to change the reference date. Many eligibility rules say something like 'age as on 1 August' or 'age on the last date of application'. Set that date instead of today, and the result shows whether you meet the limit and by how much. Parents use the same approach to check whether a child meets the minimum age for school entry in a particular year.
You can also use the calculator in reverse for planning. Knowing your exact age helps when you are working out how many years remain until retirement, when a policy matures, or when you become eligible for senior citizen benefits on deposits and tax. The result also shows the weekday you were born on and how many days remain until your next birthday, which is handy for planning a celebration or a renewal. If a document shows a different date of birth from the one you remember, use the one in your official records, because that is what institutions will check. The result is only as accurate as the dates you enter, so double-check both before relying on it for an important deadline.
