 How NDA Eligibility Is Calculated

The NDA eligibility is based on your age between 16.5 to 19.5 years at the time of joining the National Defence Academy. Here’s how it works:

• NDA 1 generally requires DOB between 2nd July 2006 – 1st July 2009 (for 2025).

• NDA 2 requires DOB between 2nd January 2007 – 1st January 2010 (for 2025).

• These cut-off dates are auto-updated every year by the tool logic. So you don’t need to calculate manually
