Usage

From source file:Main.java

public static void main(String[] args) {

    LocalDate today = LocalDate.now();
    LocalDate birthday = LocalDate.of(1960, Month.JANUARY, 1);

    LocalDate nextBDay = birthday.withYear(today.getYear());

    //If your birthday has occurred this year already, add 1 to the year.
    if (nextBDay.isBefore(today) || nextBDay.isEqual(today)) {
        nextBDay = nextBDay.plusYears(1);
    }//from  w w  w . jav  a  2s .  c om

    Period p = Period.between(today, nextBDay);
    long p2 = ChronoUnit.DAYS.between(today, nextBDay);
    System.out.println("There are " + p.getMonths() + " months, and " + p.getDays()
            + " days until your next birthday. (" + p2 + " total)");
