ChronoLocalDate toEpochDay() method in Java with Examples Last Updated : 29 Apr, 2019 Comments Improve Suggest changes Like Article Like Report The toEpochDay() method of a ChronoLocalDate interface is used to get this date as a EpochDay. The EpochDay is the count of the day from the 0 EpochDay which is the 1970-01-01 (ISO). The output will be in the ISO-8601 format yyyy-MM-dd. Syntax: default long toEpochDay() Parameters: This method does not accepts any parameters. Return value: This method returns a long value which is the EpochDay count of this date, not null. Below programs illustrate the toEpochDay() method: Program 1: Java // Java program to demonstrate // ChronoLocalDate.toEpochDay() method import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] args) { // create a ChronoLocalDate object ChronoLocalDate localD = LocalDate.parse("2018-12-06"); // print ChronoLocalDate System.out.println("ChronoLocalDate as EpochDay: " + localD.toEpochDay()); } } Output: ChronoLocalDate as EpochDay: 17871 Program 2: Java // Java program to demonstrate // ChronoLocalDate.toEpochDay() method import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] args) { // create a ChronoLocalDate object ChronoLocalDate localD = LocalDate.parse("2021-06-30"); // print ChronoLocalDate System.out.println("ChronoLocalDate as EpochDay: " + localD.toEpochDay()); } } Output: ChronoLocalDate as EpochDay: 18808 Reference: https://docs.oracle.com/javase/9/docs/api/java/time/chrono/ChronoLocalDate.html#toEpochDay-- Comment More infoAdvertise with us K Kirti_Mangal Follow Improve Article Tags : Java Java-Functions Java-time package Java-ChronoLocalDate Practice Tags : Java Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
