How to get a date by giving the week of the month and day of the week

How do i get a date by giving the week of the month and day of the week.

Example: If i need the third tuesday of November 2018.

Week of month : 3,
Day of Week : 3

Expected date is : Nov 20 2018

But the value we get is : Nov 13 2018. Since the start day of the month (thursday) is less than than the expected day(tuesday).

   Calendar calendar = Calendar.getInstance();  

   calendar.set(Calendar.YEAR,2018 );  

   calendar.set(Calendar.MONTH, 10);  

   calendar.set(Calendar.WEEK_OF_MONTH, 3);  

   calendar.set(Calendar.DAY_OF_WEEK, 3);  

   System.out.println("Time " + calendar.getTime());

How do i get the correct date??

If you just input the week of month and the day of week, then how do you determine which month it is?

WEEK_OF_MONTH should be 4. Since 20th falls on 4th week of Nov. Works fine with this value. Tested.

The Calendar class has design problems and is long outdated. Use java.time, the modern Java date and time API. Depending on your definition of week numbers in a month the WeekFields class may be useful.

If you are using Java 8, you can do this,

import java.time.DayOfWeek;

import java.time.LocalDate;

import java.time.temporal.TemporalAdjusters;



public class Main {

    public static void main(String args) {

        LocalDate input = LocalDate.now();

        int ordinal = 3;

        DayOfWeek weekday = DayOfWeek.THURSDAY;

        TemporalAdjuster ta = TemporalAdjusters.dayOfWeekInMonth(ordinal, weekday) ;

        LocalDate adjusted = input.with( ta );

        System.out.println(adjusted.toString());

    }



}

I have taken it from here, and there are more ways to do that in the given link.

You can use the following code :

LocalDate.now().with(TemporalAdjusters.dayOfWeekInMonth(3, DayOfWeek.TUESDAY));

This will output :

2018-11-20
