Enter a date of birth above to check school admission eligibility.

Some states permit admission at 5+ or set a different cutoff date. Always verify with the school or the state education department notification.

Completed age vs running age — know the difference

India has two ways of stating age, and mixing them up on a form can cost you an application. Your completed age is the number of full years, months and days you have actually finished — if you were born on 15-05-2000, then on 11-07-2026 your completed age is 26 years, 1 month, 26 days. Your running age is the year of life you are currently in — the same person is "running 27". Grandparents and astrologers use running age; every official form, exam application and legal document uses completed age. This calculator shows both, clearly labelled, so you never write the wrong one.

Age as on a cutoff date — why exam forms ask this

Recruitment bodies do not check your age on the day you apply. They fix a single cutoff date and every candidate's minimum and maximum age is measured on that one day. That is why notifications say "candidate must have attained 18 years and must not have attained 30 years as on 01-08-2026". Being even one day over the limit on the cutoff date makes an application invalid — and every year candidates are rejected for exactly this.

RecruitmentCommonly used cutoff pattern
SSC (CGL, CHSL, MTS)Usually 01 January or 01 August of the exam year
UPSC Civil ServicesUsually 01 August of the exam year
Banking (IBPS, SBI)Usually the 1st of the notification month (often 01 July / 01 August)
State PSCs (TNPSC, BPSC etc.)Usually 01 July of the exam year
Class 1 school admission31 March of the admission year

These are typical patterns, not guarantees — the exact cutoff is printed in each notification. Use the preset chips above, or type the precise date from your notification into the "age as on" field.

How to write your age on government forms

Most Indian forms want age in the exact format "__ years, __ months, __ days as on DD-MM-YYYY". This calculator generates that sentence for you with a one-tap copy button, using the same completed-age method that recruitment bodies use. Double-check that the date of birth you enter matches your Class 10 certificate — for government purposes, the matriculation certificate DOB is final.

Born on 29 February?

If you are a "leapling", your birthday exists only once every four years. For age computation, the accepted convention — which this calculator follows — is that you complete your next year of age on 1 March in non-leap years. Your next-birthday countdown also lands on 1 March when 29 February does not exist that year, and returns to 29 February in leap years.

How this calculator counts

Method: completed years first, then completed months, then leftover days — with days borrowed from the actual length of the previous month (28, 29, 30 or 31 days). This is the standard borrow method used for official age computation, so a result like "17 years, 11 months, 30 days as on the cutoff" correctly means you have not attained 18.

Because real months have different lengths, the days figure can differ by a day from calculators that assume every month has 30 days. When a notification says "attained X years", only the completed-years figure matters — the months and days simply show how far past (or short of) the birthday you are.

Frequently asked questions

How do I calculate my age as on 01-08-2026 for an exam form?

Enter your date of birth, then tap the 01-08-2026 preset chip (or type any date in the "age as on" field). The calculator shows your completed age in years, months and days on that exact date, plus a ready-to-copy sentence in the format government forms expect.

Should I write completed age or running age on government forms?

Always write your completed age — the full years, months and days you have actually finished. Running age (the year you are currently in) is a colloquial Indian convention and is never used on official forms, exam applications or legal documents.

I was born on 29 February. When do I complete a year of age?

In non-leap years, a 29 February birthday is treated as completed on 1 March. This calculator follows that convention, which matches the general legal reading in India: you attain the next year of age on 1 March when there is no 29 February.

Why does my age in days differ slightly from another calculator?

Most differences come from how the days component borrows from months of different lengths (28, 29, 30 or 31 days). This calculator uses the standard borrow method — the same approach used by major international calculators and accepted for official age computation.

What is the minimum age for Class 1 school admission in 2026?

Under the NEP-aligned guideline followed by CBSE, a child should be 6 years or older as on 31 March of the admission year for Class 1. Some states apply slightly different cutoffs, so use the school admission checker on this page and verify with your state or school notification.

Can I calculate age as on a future date?

Yes. Set any future date in the "age as on" field — useful for checking whether you will meet a minimum or maximum age limit on an upcoming exam cutoff, joining date or retirement date.

Disclaimer: This is an educational computation aid. Age is computed by the standard borrow method (completed years, months and days). Exam cutoff patterns shown on this page are indicative — the exact cutoff date and age limits are those printed in the official notification, which always prevails. The Class 1 admission check follows the NEP-aligned 6-years-as-on-31-March guideline used by CBSE; state boards and individual schools may notify different cutoffs. For all government purposes, the date of birth recorded in your Class 10 (matriculation) certificate is authoritative. Always verify eligibility with the recruiting body or school before applying.
