Frequently Asked Questions
Is this age calculator officially provided by NDA?
No. FreeApplyTools is an independent utility platform. However, our engine is hardcoded to strictly follow the official NDA notification rules and cut-off dates for 2026.
What is the official Cut-off Date for age calculation?
For the 2026 cycle, NDA calculates your exact age as on July 1, 2026. Our calculator automatically uses this exact date.
Common NDA & NA (All Categories) Age Eligibility Errors
"Applying under wrong category relaxation"
Many candidates select General instead of their eligible reservation category, missing out on age relaxation of up to 5–10 years for OBC/SC/ST.
"Incorrect DOB entered during registration"
Even a single-day typo can render you ineligible. Always cross-check your DOB against your 10th certificate before submitting.
"Cut-off date confusion"
NDA calculates age as on July 1, 2026 — not the exam date or application date. Our calculator already uses this exact date.
