Many government exams, scholarship applications, job notifications and admission forms specify a precise age criterion — for example, "must not exceed 25 years as on 1st July" — and even a few days' difference can decide eligibility. This calculator works out your exact age in years, months and days as of today, so you can quickly check where you stand against such cut-offs.

The calculation accounts for varying month lengths and leap years: it compares your birth date to today's date, borrows days from the previous month when needed, and borrows a year from the month count when the month difference goes negative — the same logic used in manual age calculation for official documents.
