🎂 Age Calculator
Find your exact age in years, months and days — plus total time lived and a countdown to your next birthday.
About Age Calculator
Enter your date of birth and this tool calculates your exact age in years, months, and days as of today (or any date you choose). It also breaks your life down into total months, weeks, days, and hours lived, tells you which day of the week you were born, and counts down the days to your next birthday.
Age is calculated calendar-accurately — months and leap years are handled properly, not approximated as "365.25 days". Useful for forms, eligibility checks, birthday planning, or just curiosity. Everything runs locally in your browser; no date is ever sent anywhere.
