What date, month, year, day-of-week, day-of-month, day-of-year is it today? If we want to answer these question we can use java.util.Calendar and java.util.GregorianCalendar which is the implementation of Calendar abstract class.

These classes can help us to get integer value such as date, month, year from a Date object. Let’s see the example code.

package org.kodejava.util;

import java.util.Calendar;

public class CalendarExample {
    public static void main(String[] args) {
        // Get various information from the Date object.
        Calendar cal = Calendar.getInstance();
        int day = cal.get(Calendar.DATE);
        int month = cal.get(Calendar.MONTH) + 1;
        int year = cal.get(Calendar.YEAR);
        int dow = cal.get(Calendar.DAY_OF_WEEK);
        int dom = cal.get(Calendar.DAY_OF_MONTH);
        int doy = cal.get(Calendar.DAY_OF_YEAR);

        System.out.println("Current Date: " + cal.getTime());
        System.out.println("Day         : " + day);
        System.out.println("Month       : " + month);
        System.out.println("Year        : " + year);
        System.out.println("Day of Week : " + dow);
        System.out.println("Day of Month: " + dom);
        System.out.println("Day of Year : " + doy);
    }
}

Here is the result of this example:

Current Date: Wed Sep 15 17:34:44 CST 2021
Day         : 15
Month       : 9
Year        : 2021
Day of Week : 4
Day of Month: 15
Day of Year : 258

You might also want to try to use the Joda Time library for this. Here another example for getting information about date and time using Joda: How do I get date / time fields of date in Joda?.
