LocalDate ofEpochDay() method in Java with Examples

The ofEpochDay(long epochDay) method of LocalDate class in Java is used to obtain an instance of LocalDate from the epoch day count. Epoch day is 01-01-1970(DD-MM-YYYY). This is considered as a start of the epoch day. The method returns the LocalDate by adding the passed days into Epoch date i.e. 01-01-1970. Suppose 2 is passed as a parameter, the method will return 03-01-1970 (2 is added to '01' from the epoch day(DD)). Similarly, if 365 is passed then a whole new year will be added to the epoch date. Syntax:

public static LocalDate ofEpochDay(long epochDay)

Parameters: This method accepts one parameter epochDay which is the conversion base. Return Value: This method returns the localdate after conversion. Exceptions: This method throws DateTimeException if the epoch day exceeds the supported date range. Below programs illustrate the ofEpochDay(long epochDay) method in Java: Program 1:

Java

// Java program to demonstrate
// LocalDate.ofEpochDay(long epochDay) method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // Create LocalDate object
        LocalDate localdate
            = LocalDate.ofEpochDay(100);

        // Display full date
        System.out.println("Date: "
                           + localdate);
    }
}

Output:

Date: 1970-04-11

Program 2:

Java

// Java program to demonstrate
// LocalDate.ofEpochDay(long epochDay) method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // Create LocalDate object
        LocalDate localdate
            = LocalDate.ofEpochDay(365);

        // Display date
        System.out.println("Date: "
                           + localdate);
    }
}

Output:

Date: 1971-01-01
