Age requirement: 16.5–19.5 years. No category relaxation for NDA — the window is the same for every category. Unmarried male and female candidates eligible; Class 12 appearing candidates may apply (Physics & Mathematics required for Navy and Air Force wings). Birth windows roll forward every cycle — always confirm against the current official notification PDF. Source: UPSC NDA & NA (I) 2026 and (II) 2026 Notifications.
Why the crucial date matters more than your age today
Commissions do not measure your age when you fill the form or sit the paper. They measure it on one fixed day — the crucial date printed in the notification. A birthday two weeks after the crucial date belongs to the next cycle, not this one. And they count completed years: turning the limit age on the crucial date itself puts you out unless the notification states the limit is inclusive.
How to check your eligibility
- Enter the date of birth printed on your Class 10 / Matriculation certificate — that is the only document commissions accept.
- Keep the crucial date as shown (change it only if you are testing a different notification cycle).
- Pick your category so the relaxation is added to the upper limit correctly.
- Read the verdict, then confirm it against the official notification before you apply.
