How exact age is calculated
Your age is computed by walking the real calendar: count full years from your birthday, then full months, then the days left over — the same way age is counted on official documents. That means no approximation errors from assuming 30-day months or 365-day years, and leap-year birthdays are handled correctly. The table converts the same age into total months, weeks, days and hours.
