The Vietnam Draft Lottery Calculator is a powerful tool designed to help users estimate their potential draft risk based on historic Vietnam War lottery data from 1970 to 1972. During the Vietnam War, the U.S. military held lotteries to determine the order in which young men would be drafted for service. Each lottery assigned numbers to birthdates, creating a historical record of draft risk for every eligible individual. This calculator brings that historical data to life, allowing users to see their draft number, risk level, and percentile based on their birthdate and selected lottery year.

Whether you’re a history enthusiast, a student researching military history, or simply curious about your place in this historic lottery, the Vietnam Draft Lottery Calculator provides a clear, user-friendly interface for exploring draft outcomes.
