About NDA Calculator

Last updated

NDA Calculator exists to answer one question quickly and correctly: can I appear in the NDA exam with my date of birth?

Every year thousands of students and parents search for the NDA age limit and get a mix of conflicting answers. The rule is actually simple. UPSC checks your age on the day the course commences, and it publishes an exact date of birth window for each exam. The calculator applies that rule to your date of birth, shows your age on the course start date, and lists every NDA exam you can still take.

How we keep it accurate

  • Windows are worked out from the 16.5 to 19.5 year rule and checked against the date of birth ranges in UPSC notifications.
  • Exam and notification dates come from the UPSC Annual Calendar. Anything not yet notified is clearly marked as expected.
  • Every page links to the official source so you can confirm for yourself.

Private by design

The calculator runs in your browser. Your date of birth never leaves your device. Read the Privacy Policy for details.

Independent, not official
