The following code snippet shows you a various way to get the quarter of a given date. Some methods that we use below are:

• Using the new java.time API of Java 8 IsoFields.QUARTER_OF_YEAR.
• Using Java 8 DateTimeFormatter pattern of Q or q. The length of “q” give us a different result.
• Using java.util.Date.
• Using java.util.Calendar.
• Get the quarter from an array of string.

Let’s see the code snippet in action.

package org.kodejava.datetime;

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.time.temporal.IsoFields;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;

public class DateQuarter {
    public static void main(String[] args) {
        // Using Java 8
        LocalDate now = LocalDate.now();
        int quarter = now.get(IsoFields.QUARTER_OF_YEAR);
        System.out.println("quarter  = " + quarter);

        // Using DateTimeFormatter Q / q, set the Locale to get value
        // in local format
        String quarter1 = LocalDate.of(2023, 8, 17)
                .format(DateTimeFormatter.ofPattern("q", Locale.US));
        String quarter2 = LocalDate.of(2023, 8, 17)
                .format(DateTimeFormatter.ofPattern("qq", Locale.US));
        String quarter3 = LocalDate.of(2023, 8, 17)
                .format(DateTimeFormatter.ofPattern("qqq", Locale.US));
        String quarter4 = LocalDate.of(2023, 8, 17)
                .format(DateTimeFormatter.ofPattern("qqqq", Locale.US));
        System.out.println("quarter1 = " + quarter1);
        System.out.println("quarter2 = " + quarter2);
        System.out.println("quarter3 = " + quarter3);
        System.out.println("quarter4 = " + quarter4);

        // Using older version of Java
        Date today = new Date();
        quarter = (today.getMonth() / 3) + 1;
        System.out.println("quarter = " + quarter);

        // Using java.util.Calendar object. For certain date
        // we can set the calendar date using setTime() method.
        Calendar calendar = Calendar.getInstance();
        quarter = (calendar.get(Calendar.MONTH) / 3) + 1;
        System.out.println("quarter = " + quarter);

        // Custom the quarter as text
        String[] quarters = new String[]{"Q1", "Q2", "Q3", "Q4"};
        String quarterString = quarters[quarter - 1];
        System.out.println("quarterString = " + quarterString);
    }
}

And here are the result of the code snippet above:

quarter  = 1
quarter1 = 3
quarter2 = 03
quarter3 = Q3
quarter4 = 3rd quarter
quarter = 1
quarter = 1
quarterString = Q1
