Exact time, measured properly: your age to the day between any two dates, working days counted without weekends, and two exam eligibility checkers, for the NDA and the UPSC civil services, built on the official age windows and attempt rules.
Every result on these pages comes from the real calendar, leap years included, and the eligibility tools state their cut-off logic in plain words on the page. Exam rules do change between notifications, so treat the checker as a fast first answer and confirm against the current official notice before you act on it.
