About this tool
The Age Calculator turns a birth date into a complete age breakdown: years, months, and days, plus total days lived and a countdown to the next birthday. Because you can also set a custom target date, it doubles as a date-difference calculator for anniversaries, contracts, visa windows, and eligibility cut-offs.
Everything runs instantly in your browser. There is no form to submit and no account to create — change either date and the result updates as you type.
What people use it for
- Check exact age in years, months, and days for school enrollment, sports leagues, or visa and retirement eligibility rules that use precise cut-off dates.
- Work out someone's age on a specific past or future date, such as the first day of a school year or the date of a scheduled exam.
- Count the exact number of days between two dates for notice periods, probation windows, or medication schedules.
- Find out which weekday you were born on and how many days remain until your next birthday.
Tips for better results
- Set the target date to something other than today to answer questions like "how old will I be on June 1, 2030?"
- For eligibility rules phrased as "must be 18 by the start date", enter the start date as the target date rather than checking today's age.
- Total days lived is handy for 10,000-day and 20,000-day milestone celebrations — a fun alternative to birthdays.
