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 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 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
