Wondering how your final written exam marks stack up after applying negative marking rules?
Many CDS aspirants across India calculate their age incorrectly.
Not because they can't do the math. But because UPSC doesn't calculate age on the exam date, they calculate it on the course commencement date. That's a gap of several months. And that gap can change whether you're eligible or not.
This CDS age calculator for India fixes that. Enter your date of birth, pick your academy and exam cycle, and it tells you exactly where you stand — based on the official UPSC CDS notification.
How to Use This CDS Age Calculator
It takes six inputs and about ten seconds.
Step 1 — Exam cycle. Choose CDS 1 2026, CDS 2 2026, or any cycle up to CDS 2 2028.
Step 2 — Date of birth. Use the exact DOB from your Class 10 Matriculation certificate.
Step 3 — Gender. Women in India are eligible only for OTA.
Step 4 — Marital status. This directly affects your result. Fill this in honestly.
Step 5 — Target Academy. IMA, INA, AFA, or OTA.
Step 6 — DGCA CPL (AFA only). Applying for the Air Force Academy with a valid Commercial Pilot Licence from DGCA India? Tick this box. Your upper age limit extends from 24 to 26 years.
Hit Check Eligibility. You get three things instantly — your current age, your age on the actual course joining date, and a clear eligible or not eligible verdict with the reason.
CDS Age Limit 2026 & 2027 — Official DOB Windows
These dates come directly from the UPSC CDS II 2026 notification and projected data for 2027.
| Academy | Age Limit | CDS 2 2026 | CDS 1 2027 |
|---|---|---|---|
| IMA | 19–24 yrs | 1 Jul 2003 – 1 Jul 2008 | 2 Jan 2004 – 1 Jan 2009 |
| INA | 19–24 yrs | 1 Jul 2003 – 1 Jul 2008 | 2 Jan 2004 – 1 Jan 2009 |
| AFA | 20–24 yrs | 1 Jul 2003 – 1 Jul 2007 | 2 Jan 2004 – 1 Jan 2008 |
| OTA | 19–25 yrs | 1 Jul 2002 – 1 Jul 2008 | 2 Jan 2003 – 1 Jan 2009 |
AFA: upper limit is 26 years for valid DGCA CPL holders. CDS 1 & 2 2027 windows are projected from official UPSC historical patterns. Will be updated on notification release.
One thing that catches people off guard — OTA's course starts in October, not July. IMA, INA, and AFA all commence in July. Same exam cycle, different joining dates. The CDS 2 age calculator on this page accounts for that difference automatically for each academy.
Edge Cases This Tool Handles
The CDS age limit calculator on this page isn't just a basic date subtractor. It handles situations that a generic calculator would get wrong.
Boundary dates. Born exactly on 1 Jul 2003 for CDS 2 2026 IMA — eligible. Born on 30 Jun 2003 — not eligible. One day is the difference. The tool catches this.
The OTA age window is wider. You might be overage for IMA, INA, or AFA at 24 — but OTA goes up to 25. If you're in that gap year, the CDS age calculator for OTA will show you're still eligible for OTA even when IMA flags you as overage.
AFA's minimum age is 20, not 19. Unlike IMA and INA. A 19-year-old is ineligible for AFA specifically, and the tool flags this clearly.
Married candidates. Not eligible for any academy under any circumstances. The tool returns the exact reason, not a vague rejection.
Frequently Asked Questions
What is the age limit for the CDS exam in India?
Depends on which academy you're targeting. IMA and INA — 19 to 24 years. AFA — 20 to 24 years, though if you hold a DGCA CPL, that goes up to 26. OTA — 19 to 25 years. One thing most people get wrong: UPSC doesn't check your age on the exam date. They check it on the course joining date, which is months later.
Can I use this as a CDS 2 age calculator for the 2026 cycle?
Yes. Select CDS 2 2026 from the dropdown. The tool uses the exact DOB windows from the official UPSC CDS II 2026 notification — 1 Jul 2003 to 1 Jul 2008 for IMA and INA, and 1 Jul 2002 to 1 Jul 2008 for OTA.
I need an age calculator for CDS 2027 — does this cover that?
Both CDS 1 2027 and CDS 2 2027 are in the dropdown. The 2027 DOB windows are projected from UPSC's historical pattern — CDS 1 cycles have always started on January 2nd, CDS 2 on July 1st. The moment the official notification drops, these get updated.
Is there age relaxation for SC/ST/OBC in CDS?
No. Zero. CDS is one of the few UPSC exams where the age limit is identical for all categories — General, OBC, SC, ST, and EWS. No relaxation of any kind.
