Age & Date Calculator

Calculate your exact age, find the difference between any two dates, see what day you'll turn a milestone age, and estimate your retirement date — all instantly.

How It Works

  1. Enter your birthdate to instantly see your exact age in years, months, days, weeks, and hours.
  2. Use the Between Dates tab to calculate the precise gap between any two dates.
  3. The Milestone tab tells you what day of the week you'll turn any age.
  4. The Retirement tab estimates your retirement date based on your desired retirement age.
