Christmas Count-down Clock with Java

This tutorial will show how to make a simple java program that will count how many day there are till Christmas. The package being used to handle the dates is java.time . If you are unfamiliar with this package here is a quick intro on how to use the package.

The Christmas Count-down Clock code works like this. The today variable gets today’s date

Variable ChristmasDay is set to December 25 2020, which is this years Christmas.

Note that if Christmas has already past for this year, the Years() in java.time is given a 1 to represent Christmas being a Full year away from the current date.

Variable p gets the difference between today’s date and next years Christmas

import java.time.LocalDate;// importing LocalDate class
import java.time.Month;// importing Month class
import java.time.Period;// importing Period class
import java.time.temporal.ChronoUnit;// importing ChronoUnit class


public class aaa {
  public static void main(String[] args) {
	  
	  LocalDate today = LocalDate.now();//getting current date 
	 
	  LocalDate ChristmasDay = LocalDate.of(2020, Month.DECEMBER, 25);// setting Christmass day 

	  LocalDate nextXmas = ChristmasDay.withYear(today.getYear());// Next year Christmas 

	  //Add 1 if Christmas has past this year  
	  if (nextXmas.isBefore(today) || nextXmas.isEqual(today)) {
		  nextXmas = nextXmas.plusYears(1);
	  }

	  Period p = Period.between(today, nextXmas);
	  long p2 = ChronoUnit.DAYS.between(today, nextXmas);// nanoseconds in days till Christmas 
	  System.out.println("There are " + p.getMonths() + " months, and " +
	                     p.getDays() + " days until Christmas! (" +
	                     p2 + " total)");
  }
}

Output :

There are 0 months, and 19 days until Christmas! (19 total)
