Joda-Time: Get first/second/last sunday of month
public class Time {
public static void main(String[] args) {
System.out.println(getNthOfMonth(DateTimeConstants.SUNDAY, DateTimeConstants.SEP, 2012));
}
public static LocalDate getNthOfMonth(int day_of_week, int month, int year) {
LocalDate date = new LocalDate(year, month, 1).dayOfMonth()
.withMaximumValue()
.dayOfWeek()
.setCopy(day_of_week);
if(date.getMonthOfYear() != month) {
return date.dayOfWeek().addToCopy(-7);
}
return date;
}
}
You can try something like that:
public class Foo {
public static LocalDate getNthSundayOfMonth(final int n, final int month, final int year) {
final LocalDate firstSunday = new LocalDate(year, month, 1).withDayOfWeek(DateTimeConstants.SUNDAY);
if (n > 1) {
final LocalDate nThSunday = firstSunday.plusWeeks(n - 1);
final LocalDate lastDayInMonth = firstSunday.dayOfMonth().withMaximumValue();
if (nThSunday.isAfter(lastDayInMonth)) {
throw new IllegalArgumentException("There is no " + n + "th Sunday in this month!");
}
return nThSunday;
}
return firstSunday;
}
public static void main(final String[] args) {
System.out.println(getNthSundayOfMonth(1, DateTimeConstants.SEPTEMBER, 2012));
System.out.println(getNthSundayOfMonth(2, DateTimeConstants.SEPTEMBER, 2012));
System.out.println(getNthSundayOfMonth(3, DateTimeConstants.SEPTEMBER, 2012));
System.out.println(getNthSundayOfMonth(4, DateTimeConstants.SEPTEMBER, 2012));
System.out.println(getNthSundayOfMonth(5, DateTimeConstants.SEPTEMBER, 2012));
}
}
Output:
2012-09-02
2012-09-09
2012-09-16
2012-09-23
2012-09-30
This is quite an old post but possibly this answer will help someone. Use the java.time classes that replace Joda-Time.
private static LocalDate getNthOfMonth(int type, DayOfWeek dayOfWeek, int month, int year){
return LocalDate.now().withMonth(month).withYear(year).with(TemporalAdjusters.dayOfWeekInMonth(type, dayOfWeek));
}
