Age Calculator
Find your exact age in years, months, and days — or calculate the difference between any two dates. Instant results.
How to Use the Age Calculator
Enter your date of birth and click "Calculate My Age." Your exact age appears instantly — in years, total months, total weeks, total days, and total hours lived. The calculator also tells you how many days until your next birthday.
For the "Between Two Dates" mode, enter any start and end date to find the exact time difference — useful for calculating experience duration, contract periods, or any date gap.
What is the formula to calculate age?
Age = Current Date − Date of Birth. The calculator accounts for leap years and variable month lengths to give a precise result. For example, if you were born on 15 March 1990 and today is 27 June 2026, your age is 36 years, 3 months, and 12 days.
Why does age matter for Indian documents?
In India, age is required for school admissions (typically 6 years as of 1 June), Aadhaar, passport, PAN card, senior citizen benefits (60+ years), and many government schemes. This calculator gives you the exact age as on any specific date — simply set the "Age as on date" field.
