For a young aspirant, the National Defence Academy is the earliest route to a Permanent Commission in the Indian Army, Navy or Air Force, and the very first filter is your date of birth. NDA has one of the tightest age windows of any defence entry, only about three years wide, so a single day can decide whether you can apply. This guide explains the NDA 1 2027 age limit, the expected date of birth (DOB) window, the minimum and maximum age, the marital status rule, the rules for women candidates and Class 12 students, accepted DOB proof and worked examples.
Status as on 10 November 2026: The NDA & NA (I) 2027 notification has not been released yet. UPSC lists it as a forthcoming examination, and as per the UPSC Programme of Examinations for 2027, the notification is scheduled for 2 December 2026, the last date to apply is 22 December 2026 and the written exam is scheduled for 11 April 2027. The age limit below is based on the official NDA & NA (I) 2026 notification. The 2027 DOB window is an expected range worked out from that pattern, not an official figure. This article will be updated as soon as UPSC publishes the NDA & NA (I) 2027 notification.
NDA 1 2027 Age Limit at a Glance (Expected)
In the NDA (I) cycle, the exam is held in April and the course begins in January of the following year. NDA (I) 2026 was conducted for the 157th NDA Course and the 119th Indian Naval Academy Course (INAC) commencing 1 January 2027. NDA (II) 2026 was conducted for the 158th NDA Course and the 120th INAC commencing 1 July 2027. If the same sequence continues, NDA (I) 2027 is expected to be for the 159th NDA Course and the 121st INAC, commencing in January 2028, and the DOB window is expected to move forward by exactly one year.

| Expected course commencement | January 2028 |

| Maximum age | About 19½ years on the date of course commencement |

Official Age Limit in the Latest NDA 1 Notification (NDA I 2026)
The expected 2027 window is based on the official rule in the NDA & NA (I) 2026 notification (Examination Notice No. 3/2026-NDA-I, dated 10 December 2025). Under the heading “Age Limits, Sex and Marital Status”, it said: only unmarried male/female candidates born not earlier than 1st July 2007 and not later than 1st July 2010 are eligible.
| Notification | Course | Course Commencing | Official DOB Range |
|---|---|---|---|
| NDA & NA (I) 2026 | 157th NDA Course and 119th INAC | 1 January 2027 | 1 July 2007 to 1 July 2010 |
| NDA & NA (II) 2026 | 158th NDA Course and 120th INAC | 1 July 2027 | 1 January 2008 to 1 January 2011 |
| NDA & NA (I) 2027 (expected) | 159th NDA Course and 121st INAC (expected) | January 2028 (expected) | 1 July 2008 to 1 July 2011 (expected) |
Notice the pattern. Each NDA cycle moves the window forward by six months, and each NDA (I) window is exactly one year later than the previous NDA (I) window. That is how the expected 2027 range is derived. Only the official 2027 notification can confirm it.
Minimum and Maximum Age for NDA 1 2027 Explained
The NDA notification does not print an age in years. It gives a DOB range, and the commonly quoted 16½ to 19½ years comes from comparing that range with the course start date. For a course starting in January 2028, a candidate born on 1 July 2011 will be exactly 16½, and a candidate born on 1 July 2008 will be exactly 19½.
- Minimum age (expected): you must be born on or before 1 July 2011. If you are born on 2 July 2011 or later, you are too young for NDA 1 2027.
- Maximum age (expected): you must be born on or after 1 July 2008. If you are born on 30 June 2008 or earlier, you are over-age for NDA 1 2027.
- Both boundary dates are inclusive, so candidates born exactly on 1 July 2008 or 1 July 2011 are eligible as per the expected range.
Same Age Limit for Army, Navy and Air Force Wings
Unlike CDS, where every academy has its own age band, NDA has one common DOB range for all its entries. The same window applies whether you choose the Army, Navy or Air Force wing of NDA, or the 10+2 Cadet Entry Scheme at the Indian Naval Academy. What changes between wings is the educational condition, not the age:
| Entry | Age Limit | Educational Qualification (as per NDA I 2026) |
|---|---|---|
| Army wing of NDA | Common DOB range | Class 12 pass (10+2 pattern) or equivalent, in any stream |
| Air Force wing of NDA | Common DOB range | Class 12 pass with Physics, Chemistry and Mathematics |
| Naval wing of NDA | Common DOB range | Class 12 pass with Physics, Chemistry and Mathematics |
| 10+2 Cadet Entry Scheme, Indian Naval Academy | Common DOB range | Class 12 pass with Physics, Chemistry and Mathematics |
NDA 1 2027 Age Limit for Women Candidates
Women have been able to apply for NDA since 2021, and the latest notification is open to unmarried male and female candidates. There is no separate age limit for women. Female candidates must fall in the same DOB window as male candidates, which is expected to be 1 July 2008 to 1 July 2011 for NDA 1 2027.
In NDA (I) 2026, 24 of the 394 approximate vacancies were for women, across the Army, Navy and Air Force wings and the Naval Academy. The written results and final merit lists for men and women are prepared separately as per the vacancies notified. The 2027 vacancy figures will be known only when the notification is released.
Marital Status Rule
Age and marital status are checked together. As per the latest notification:
- Only unmarried candidates, male or female, can apply.
- Candidates must undertake not to marry until they complete their full training.
- A candidate who marries after the date of application will not be selected for training, even if successful in this or any later examination.
- A candidate who marries during training is discharged and is liable to refund all the expenditure incurred on him or her by the Government.
Can Class 12 Students Apply for NDA 1 2027?
Yes. Candidates who are appearing in Class 12 under the 10+2 pattern, or an equivalent examination, can apply, provided their date of birth falls within the window. Under the NDA (I) 2026 rules, such candidates had to submit proof of passing Class 12 by a fixed date (10 December 2026 for that cycle), and no extension was allowed on grounds such as late board exams or delayed results. The deadline for the 2027 cycle will be given in the new notification.
However, candidates appearing in the Class 11 exam are not eligible, even if their age is within the range. This matters for younger aspirants: a student born close to 1 July 2011 may be age-eligible but still in Class 11, and in that case cannot apply for NDA 1 2027.
NDA 1 2027 DOB Examples (Based on the Expected Range)
| Candidate’s DOB | NDA 1 2027 (Expected) | Comment |
|---|---|---|
| 30 June 2008 | Not eligible | Over-age by one day |
| 1 July 2008 | Eligible | First valid date; likely the last NDA (I) chance |
| 10 December 2008 | Eligible | Expected to be over-age for NDA (II) 2027, so NDA 1 2027 may be the final attempt |
| 15 March 2010 | Eligible | Comfortably inside the window; also expected to be eligible for later cycles |
| 1 July 2011 | Eligible (age) | Last valid date; must also be in or past Class 12 |
| 2 July 2011 | Not eligible | Under-age by one day; wait for the next cycle |
If NDA (II) 2027 follows the same six-month shift, its window would be expected around 1 January 2009 to 1 January 2012. Treat this only as a planning guide, because UPSC confirms each window in its own notification. Since the window is about three years wide and NDA is held twice a year, most candidates get around six chances to appear, depending on their exact DOB and Class 12 timing.
Is There Any Age Relaxation in NDA 1 2027?
No. The NDA notification does not give any age relaxation for SC, ST, OBC, EWS, wards of defence personnel or any other category. The same DOB range applies to every candidate. Category status affects only the application fee: in NDA (I) 2026, SC/ST candidates, female candidates and certain wards of JCOs/NCOs/ORs were exempted from the Rs 100 fee, but there was no relaxation in age.
Which Date of Birth Does UPSC Accept?
- UPSC accepts only the DOB entered in the Matriculation or Secondary School Leaving Certificate, or in a certificate recognised by an Indian university as equivalent to Matriculation, or in a certified extract from a university’s Register of Matriculates.
- Horoscopes, affidavits, birth extracts from a Municipal Corporation, service records and similar documents are not accepted.
- Only the DOB recorded in your Class 10 or equivalent certificate on the date you apply will be accepted, and no later request to change it will be considered.
- Once you claim a DOB in the online application, no change is allowed later, at this or any subsequent examination. Any variation found at a later stage can lead to disciplinary action, so enter the date in your Universal Registration Number (URN) profile with care.
- Candidates called for the SSB interview must carry their original Matriculation or equivalent certificate as proof of date of birth.
