Formula
Age = Today's date − Date of birth, expressed as complete years, remaining months and remaining days.

Frequently Asked Questions
▶ How is exact age calculated?
Exact age counts completed years first, then completed months after your last birthday, then the remaining days. This calculator handles leap years automatically.
▶ Can I use this for official forms?
Yes — the years/months/days format matches what most government forms, job applications and exams ask for when they require age as on a specific date.
▶ Does it account for leap years?
Yes. The calculation is based on real calendar dates, so 29 February and varying month lengths are handled correctly.
▶ Can I calculate age for a future or past date?
This tool calculates age as of today. For the difference between any two dates, use our Date Difference calculator.

How age is actually calculated
Age is counted in completed years, then completed months, then remaining days — not as a decimal. Someone who is 31 years and 11 months is still 31, not 32.
The calculation walks the calendar rather than using an average year length, which is why leap years are handled correctly. A person born on 29 February has a birthday only in leap years; most systems, including this one, treat 1 March as the effective birthday in non-leap years.
Indian vs East Asian age reckoning
India uses the international system — you are zero on the day you are born and turn one on your first birthday. Traditional Korean age counting, by contrast, started at one and added a year at New Year, which is why the same person could be reckoned two years older there. That system has now largely been replaced by international reckoning in official use.
Where exact age matters in India
School admission — most states set a cut-off date, and a few days can decide the academic year.
Government job applications — upper age limits are checked against a specific reference date, not the application date.
Competitive exams — eligibility windows are strict and calculated to the day.
Senior citizen benefits — higher FD rates, higher tax exemption limits and railway concessions typically start at 60.
Insurance premiums — priced by completed age, so buying a term policy a week before a birthday can lock a lower rate for the whole term.
PAN, passport and driving licence — minimum age requirements are date-specific.
Retirement and pension — dates of superannuation are computed exactly.
Common mistakes
Treating age as a decimal. 31.9 years is still age 31 for every official purpose.
Assuming a year is 365 days when counting total days across leap years.
Confusing "age as on" a reference date with age today — government forms almost always specify a reference date.
Forgetting that 29 February birthdays need special handling in non-leap years.
Using approximate month lengths, which drifts by several days a year.
More questions
▶ How is age calculated exactly?
In completed years, then completed months, then remaining days, by walking the calendar rather than using an average year length. Leap years are handled automatically.
▶ What if I was born on 29 February?
Your birthday falls only in leap years. Most systems, including this calculator, treat 1 March as the effective birthday in non-leap years.
▶ What is 'age as on' a date?
Government forms and exams usually specify a reference date, and eligibility is judged against that date rather than the day you apply. Always check which date applies.
▶ At what age do senior citizen benefits start in India?
Generally 60 for higher fixed deposit rates and higher income tax exemption limits, with some benefits at 80 for very senior citizens.
▶ Does age affect insurance premiums?
Yes, term and health insurance are priced by completed age. Buying shortly before a birthday can lock in a lower premium for the whole policy term.
▶ How many days old am I?
Enter your date of birth above and the calculator gives your total days, months and hours alongside your age in years, months and days.
