import java.time.Month;
import java.time.Period;

public class Main {
  public static void main(String[] argv) {
    LocalDate today = LocalDate.now();
    LocalDate java8Release = LocalDate.of(2014, Month.MARCH, 14);
    Period period = Period.between(java8Release, today);
    System.out.println("Period between today and Java 8 release : " + period);
    System.out.println("Period between Java 8 release and today : " + Period.between(today, java8Release));

  }
}
