 * or


 * Examples :
 * returns "13"

 * When using this template to calculate a person's age at death or a person's age on a specified date (rather than the person's current age), please substitute it into the page (see Help:Substitution).
 * Example:


 * When entering dates before the Common Era, use astronomical year numbering: 1 BCE is represented by 0, 2 BCE by -1, 3 BCE by -2 etc. For example, the following expression returns the number of full years elapsed since the battle of Cannae, which took place on August 2, 216 BCE:
 * returns "1810"
 * (BCE is exactly the same as BC, so August 2, 216 BCE is also August 2, 216 BC)


 * Note :
 * This template does not check for incorrect input:
 * returns "0" (surplus days do not count as extra months)
 * returns "0" (surplus months do not count as extra years)
