HijrahDate toEpochDay() method in Java with Example

Last Updated : 27 Feb, 2020

The toEpochDay() method of java.time.chrono.HijrahDate class is used to get the number of epoch days present in between the current hijrah date and 1389-10-22.

Syntax:

public long toEpochDay()

Parameter: This method does not accept any argument as a parameter.

Return Value: This method returns the number of epoch days present in between the current Hijrah date and 1389-10-22.

Below are the examples to illustrate the toEpochDay() method:

Example 1:

Java

// Java program to demonstrate
// toEpochDay() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // HijrahDate Object
            HijrahDate hidate = HijrahDate.now();
  
            // Getting no of ephoch days present
            // by using toEpochDay() method
            long length = hidate.toEpochDay();
  
            // Display the result
            System.out.println("EpochDay : "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

EpochDay : 18311

Example 2:

Java

// Java program to demonstrate
// toEpochDay() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // HijrahDate Object
            HijrahDate hidate
                = HijrahDate.of(1389, 10, 22);
  
            // Getting no of ephoch days present
            // by using toEpochDay() method
            long length = hidate.toEpochDay();
  
            // Display the result
            System.out.println("EpochDay : "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

EpochDay : 0
