Calculate age in Groovy from today

Trying to figure out how old someone is based on their bday. The following code gives us the number of days

def now = new Date()
def dob = new Date('08/21/1982')

println now - dob

We could divide by 365 but that isn't entirely accurate. There has to be an easy way to do this but I just can't seem to find it. Any ideas?

def current = new Date()
println current
def dob = new Date ('06/27/2000')
println dob
def res = current - dob
def age = res/365
println age

For me joda was not available so I searched another, more groovy solution and found:

def duration = groovy.time.TimeCategory.minus(
  new Date(),//date1
  new Date(session.creationTime)//date2
);
println "seconds: " + dur2.seconds;
println "min: " + dur2.minutes;
println "hours: " + dur2.hours;

Or using Java 8 and Groovy 2.3 RC (if you want to be on the bleeding edge) ;-)

import java.time.*

LocalDate today    = LocalDate.now()
LocalDate birthday = LocalDate.of( 1982, Month.AUGUST, 8 )

Period period = Period.between( birthday, today )

println """$period.years years, 
          |$period.months months, 
          |$period.days days""".stripMargin()

Here is a sleek alternative using joda time :)

@Grab('joda-time:joda-time:2.3')
import org.joda.time.Period
import org.joda.time.DateTime

def now = new DateTime()
def dob = new DateTime(1982, 8, 21, 0, 0)

def period = new Period(dob, now)

println """$period.years years, 
         |$period.months months, 
         |$period.days days, 
         |$period.hours hours, 
         |$period.minutes minutes
        """.stripMargin()
