How is the exact age calculated?
It counts full years, then full remaining months, then the leftover days - the same way legal and civil age is normally stated. This differs slightly from simply dividing total days by 365.
Can I use it for a past date?
Yes - set the "as of" date to any earlier or current date to find the age at that point in time.
Does it count a baby under one year correctly?
Yes. For someone under one year old the years figure is 0 and the age is shown in months and days.
