Free online age calculator. Enter your date of birth to get your exact age in years, months and days, the total number of days you've lived, and how many days until your next birthday.
Working out 'exactly how many years, months and days old today', 'days lived' or 'how long until an anniversary' is easy to get wrong by hand (leap years and uneven months trip people up). Enter the start and end dates for a precise result — useful for sign-ups, insurance, retirement and planning.
