How your age is calculated
Age is your date of birth to the reference date, broken into completed years, whole remaining months, and leftover days.

How is age calculated?
We subtract your birth date from the reference date while accounting for varying month lengths and leap years. Year-month-day breakdown matches the standard civil age used on documents.
Worked example: age by date of birth
If you were born on 14 August 1996 and today is 15 August 2026, your completed age is 30 years, 0 months and 1 day — exactly the figure a government form asks for. The same span is about 10,957 days or 1,565 weeks. Set the 'age as on' date to any cutoff (say, 1 January 2027 for an exam notification) to see your age precisely on that date.
Age for government job and exam eligibility
Most Indian government exams (UPSC, SSC, banking, railways) state an age cutoff 'as on' a specific date, and only completed years count — being 30 years and 11 months on the cutoff date still reads as 30. This calculator's year-month-day breakdown plus the 'as on' field gives you the exact number for eligibility checks. Reserved categories (OBC/SC/ST/PwBD) get relaxation on upper age — always verify against the specific notification.
How this calculator works
Age is computed by calendar subtraction that respects unequal month lengths and leap years (Feb 29 birthdays roll to 1 March in common years, per standard civil practice). Results include years-months-days, total months, weeks, days and hours. All maths runs in your browser — nothing is stored or uploaded. Content reviewed and updated for 2026.
Frequently asked questions
How do I calculate my exact age from my date of birth?
Enter your birth date above — the calculator counts completed years, months and days between your date of birth and the reference date ('as on' today unless you change it). Example: born 14 August 1996 means age 30 years, 0 months, 1 day on 15 August 2026.
Why does this differ from my informal age?
Informal age often rounds up at half-birthdays or counts the year you're 'running.' Civil age strictly counts completed years — this is the standard used for visas, government forms and pension/senior-citizen benefits.
How do I check age eligibility for a government job?
Set the 'age as on' field to the cutoff date in the notification (e.g., 1 August of the exam year). Only completed years count — 30 years 11 months reads as 30. Category-wise relaxation then applies per the notification.
Does this handle leap years?
Yes. Indian civil age rules count leap day (Feb 29) birthdays on March 1 in non-leap years. Total day counts implicitly include leap years (365 vs 366 days).
Can I check someone else's age on a past date?
Yes — set the 'Age as on' field to any date. Useful for checking eligibility cutoffs (e.g., exam age as on 1 Aug of a given year).
What's the difference between total days and years?
Total days is the raw calendar difference. Years-months-days breaks it into readable blocks. Days ÷ 365.2425 is approximate years; for legal matters always use calendar years.
