The calculator computes the difference between your date of birth and the selected 'as of' date using precise calendar arithmetic — accounting for different month lengths and leap years. It first counts full years, then remaining full months, then remaining days.
Enter a date of birth and an 'as of' date (defaults to today) to get an exact age breakdown: years, months, days, total weeks, total days, total hours, days until your next birthday, and the day of the week you were born. Handles leap-year birthdays and shows a birthday message on the day itself.
