Accuracy of information
We work to keep the calculator and articles accurate and up to date, using the UPSC Annual Calendar and the standard rule that a candidate must be between 16.5 and 19.5 years old on the day the course commences. Even so, errors can occur and rules can change. Dates for exams that have not yet been notified, including all dates after NDA I 2027 on this site, are expected values and may differ from the final notification.
Not professional advice
Nothing on this site is legal, career or counselling advice. Your own eligibility depends on your documents and on the notification for the exam you apply to. If your date of birth is close to a cut-off, check it against the official notification before paying any fee.
