What Does Exact Age Mean?
Exact age is the elapsed time between your date of birth and today, expressed as complete years, months, and days. That is more precise than simply subtracting your birth year from the current year.
The calculator also shows your total number of days lived and the weekday on which you were born. Those are date calculations, while birthday rarity compares how frequently your month and day occurred in the site's historical birth dataset.
