About Age Calculator
Age Calculator finds your exact age in years, months, and days from a date of birth, correctly accounting for varying month lengths and leap years rather than just subtracting years. It also shows total days, weeks, and months lived, and counts down to your next birthday. Beyond personal curiosity, it's useful for age-based eligibility checks, filling out forms that need exact age rather than just birth year, or calculating someone's age as of a specific past or future date.
