How It Works
Enter your birth date and the calculator instantly shows your exact age in multiple formats: years, months, days, hours, minutes, and seconds. It also calculates days until your next birthday, what day of the week you were born on, and determines your generation (Gen Z, Millennial, Gen X, etc.). The tool provides fun statistics like total days lived, total hours, and even heartbeats (estimated). All calculations happen instantly in your browser.
